Definitions
- the present invention relates to a device, method, and/or system for alleviating pressure, soreness, or pain to a person's foot resulting from the person wearing a high-heeled shoe.
- high-heels A woman's high-heeled shoe, commonly known as “high-heels” or just “heels”, is a vital part of any woman's shoe collection.
- Traditional high-heels are virtually the only accepted form of footwear for a woman attending a formal or professional event.
- high-heels have evolved and become more popular as a fashion statement, “pumps”, “stilettos”, “wedges”, and other types of casual high-heeled shoes have also achieved significant success in the marketplace.
- high-heeled shoes In contrast to flat-soled shoes such as sneakers or sandals where the weight of a woman's body is spread out over the entire foot, high-heeled shoes require that a woman carry more or most of her weight on the balls of her foot, thereby focusing significant pressure on the front area of the foot. For example, for flat, non-high-heeled shoes, less than 50% of the person's weight is distributed over the balls of the person's foot. However, for high-heeled shoes having at least a two-inch heel, over 70% of the person's weight may be borne by the balls of the person's foot, which is an increase of over 20%.
- Such discomfort may be further exacerbated as a result of the height of the heels, which elevate the person in the heel or calcaneus area of the foot. As heel height increases, the percentage of a person's weight borne by the balls of the foot also increases.
- the medical issues that may arise from wearing high-heels are not limited to pain in the front area of the foot, but may extend to other areas of the foot, ankle, knee, hip, and even the person's back.
- high-heels may significantly alter a person's natural stance, posture, and/or gait.
- flat-heeled shoes such as sneakers allow greater flexibility and movement so that the wearer can pronate her feet.
- high-heels are designed to increase a woman's height by slanting the foot forward and down while elevating the heel away from the ground, high-heels that are too flexible and unsupported may pose a risk of injury. Accordingly, a rigid structure may be beneficial to reduce foot, ankle, and other injuries.
- Devices, methods, and systems discussed herein relate to a high-heeled shoe and more particularly, for providing improved comfort and/or to alleviate foot pain related to the wearing of a high-heeled shoe.
- a high-heeled shoe may include an insole or a top outer layer and a bottom rigid structure.
- the bottom rigid structure may include a front portion, a mid portion and an end portion.
- the front portion of the bottom rigid structure may include a cavity or cut-out portion for insertion of an encapsulated member.
- the encapsulated member When the shoe is worn, the encapsulated member may expand laterally in response to an introduction of pressure on a top surface of the encapsulated member thereby dispersing pressure on the balls of the foot.
- the cavity for the encapsulated member may be configured to contact one side of a foam layer, while the other side of the foam layer contacts a bottom surface of the encapsulated member.
- the foam layer may separate the surface of the cavity from a surface of the encapsulated member.
- a high-heeled shoe may include a top rigid structure and a bottom layer.
- the top rigid structure may be shaped to have a raised end portion, a sloped mid portion and a substantially flat front portion.
- the top rigid structure may further include an embedded encapsulated member located within a cut-out or cavity of the top rigid structure.
- the bottom layer may include a flexible flat portion and a heel portion attached to a heel stake. The bottom layer may be attached to the top rigid structure such that the flexible flat portion may take the shape of the top rigid structure.

- FIG. 6 illustrates a view of a high-heeled shoe showing the different geometric planes therein in accordance with one or more embodiments described herein.
- the terms “front portion”, “mid portion” and “end portion” are used to describe different portions of the shoe.
- the front portion may correspond to the area of the shoe which contacts or corresponds with a “ball of the foot” or an area between the arch and the end of the toes—which may or might not include the toes themselves.
- the mid portion may correspond to the area of the shoe which contacts or corresponds with an arch of the foot.
- the end portion may correspond to the area of the shoe which contacts or corresponds with a heel of the foot. Accordingly, “front portion” may be used interchangeably with “ball portion”, “mid portion” may be used interchangeably with “arch portion” and “end portion” may be used interchangeably with “heel portion”.
- the term “rigid” includes, but is not limited to, different degrees of rigidity from semi-rigid (e.g., a durometer of 80) to very rigid (e.g., a durometer of 115), but preferably is within a durometer range of between about 80-115, and more preferably is within a durometer range of between about 90-105.
- FIG. 1A illustrates a platform high-heeled shoe 100 with a front portion 105 , a mid portion 110 , an end portion 115 and a heel portion 120 .
- Other portions of the shoe that hold the foot to the shoe e.g., shoe straps
- the shoe 100 is illustrated to have a heel length of over two inches, the heel length may vary.
- the heel length may be defined as the difference between the height of the heel raised above the ground and the height of the toes raised above the ground.
- the slope of the mid portion 110 and the end portion 115 may also increase.
- FIG. 1B illustrates a deconstructed view of the shoe 100 .
- the shoe 100 may include a top outer layer 130 which may be a flat, thin platform for the foot to rest upon.
- the top outer layer 130 may include a front portion 135 for placement of the toes and the balls of the foot, a mid portion 140 for placement of the arch or “middle” of the foot, and an end portion 145 for placement of the heel of the foot.
- the top outer layer 130 may be attached on top of a bottom rigid structure 150 when the shoe 100 is fully constructed.
- the bottom rigid structure 150 may include a front portion 155 , a mid portion 160 , and an end portion 165 which correspond directly and may be in physical contact with the front portion 135 , the mid portion 140 , and the end portion 145 of the top outer layer 130 , respectively.
- the bottom rigid structure 150 may include a rigid base 175 constructed out of a hard polymer or plastic and may be configured to support and withstand several hundred pounds of human weight without breaking.
- the rigid base 175 may be non-flexible (e.g., not capable of bending).
- the rigid base 175 may span the front portion 155 , the mid portion 160 and the end portion 165 of the bottom rigid structure 150 .
- An encapsulated member 170 may be inserted into the rigid base 175 .
- the rigid base 175 may be configured to form a continuous, rigid border around the edges of the encapsulated member 170 .
- the rigid base 175 may form a border of at least three-sixteenth of an inch, but the border may increase to over half an inch in some embodiments.
- the border might not be uniform in width surrounding the encapsulated member 170 .
- the border may be formed by cutting out a portion of the rigid base 175 or forming the rigid base 175 with a cavity for the encapsulated member 170 . In this manner, the encapsulated member 170 may be held in place and localized only in the front portion 155 of the bottom rigid structure 150 .
- an outer layer 180 may surround the outside edges of the rigid base 175 .
- holes 185 and 190 may be drilled or formed into the rigid base 175 which may allow the shoe 100 to minimally flex, thereby preventing the shoe 100 from cracking when a large amount of pressure is exerted on the shoe 100 by the wearer's weight.
- the holes 185 and 190 may be differently sized, and may range from 2-3 millimeters to 5-6 millimeters in diameter.
- the holes 185 and 190 may be drilled in the mid portion 160 and the end portion 165 and may be orthogonal to the surface upon which the shoe 100 is resting. As the mid portion 160 and the end portion 165 may be sloped, the holes 185 and 190 may be non-orthogonal to the mid portion 160 and the end portion 165 .
- FIG. 1C illustrates a further deconstructed view of the bottom rigid structure 150 of the shoe 100 .
- the encapsulated member 170 has been removed to better illustrate the cavity 197 .
- an optional thin foam layer 195 is shown in the cavity 197 .
- the cavity 197 may be formed by a continuous smooth wall substantially similar in shape as the thin foam layer 195 and the encapsulated member 170 .
- the cavity 197 may have a depth slightly less than the thickness of a combination of the thin foam layer 195 and the encapsulated member 170 .
- the top of the encapsulated member 170 may protrude out of the cavity 197 . Accordingly, when the top layer 130 is affixed to the bottom rigid structure 150 , the encapsulated member 170 may slightly bulge and press into the top layer 130 .
- FIG. 1D illustrates an exploded view of the shoe 100 .
- the top outer layer 130 may cover the bottom rigid structure 150 when the encapsulated member 170 is inserted into the cavity 197 of the bottom rigid structure 150 .
- FIG. 1E illustrates a side view of the shoe 100 with a cross sectional view of the front portion 155 .
- the encapsulated member 170 may be located in and/or fixed to one or more walls of the bottom rigid structure 150 forming the cavity 197 .
- the top of the encapsulated member 170 may protrude out of the cavity 197 .
- FIG. 2A illustrates a perspective view of the encapsulated member 200 , as isolated from the shoe 100 .
- pressure caused by walking on a high-heeled shoe is mostly re-absorbed by the balls of the foot since the structure of a high-heeled shoe is typically rigid and non-compliant, even if other layers or materials are included to cushion the foot.
- the inclusion of the encapsulated member 200 operates to disperse pressure placed on the foot.
- the encapsulated member 200 may be constructed of an elastic membrane (e.g., a plastic) infused with a viscous fluid or gel.
- the encapsulated member 200 may be filled with air, water and/or any other appropriate substance. While any non-rigid substance may be utilized, a gel may be preferred.
- the encapsulated member 200 when a force is exerted on the filled portion 230 of the encapsulated member 200 (e.g., by a person stepping on the shoe), lateral displacement of the substance within the filled portion 230 may result. In so doing, the encapsulated member 200 enlarges the point of pressure on the balls of the foot. Pressure caused by walking on the high-heeled shoe is thereby dispersed over a larger area (i.e., over the surface area of the encapsulated member 200 ) instead of being focused and directed on one small point. As a result, the foot may feel reduced pressure and the wearer may be able to walk a longer duration before feeling any discomfort. In one embodiment, by having the encapsulated member 200 at the front portion of the shoe 100 , the encapsulated member 200 does not suffer from increased internal pressure resulting from too large of a surface area.
- the encapsulated member 200 may be asymmetrically formed.
- the encapsulated member 200 may be configured to be symmetrical and may be a geometric (e.g., square, rectangular, triangular, trapezoidal, etc.) or non-geometric shape (e.g., shaped to mimic the footprint of a typical foot).
- the encapsulated member 200 may have an enlarged flat base 205 including a continuous flange portion 225 about the perimeter.
- the continuous flange portion 225 is about one-eighths of an inch wide. However, any width (e.g., between one-sixteenth of an inch to a half of an inch) may be possible. As viewed in FIG.
- the continuous flange portion 225 is relatively thin compared to the actual thickness of the filled portion 230 .
- the continuous flange portion 225 may function to create a space between the encapsulated member 200 and the cavity in which the encapsulated member 200 sits. This space allows the encapsulated member 200 to laterally expand without leaking or otherwise losing efficacy when pressure is exerted on a top surface of the encapsulated member 200 .
- the continuous flange portion 225 may also serve to ensure that the encapsulated member 200 is fixed to one position and does not move about the cavity (e.g., cavity 197 ).
- An optional adhesive may be used to further fix the encapsulated member 200 to the cavity 197 .
- the encapsulated member 200 may further include a top portion 210 and a bottom portion 215 separated by an indented portion 220 .
- the encapsulated member 200 may have a flat base without any flanges (not shown). In other words, the surface area of the top surface and the surface area of the bottom surface may be equal.
- FIG. 2C is a side view of the encapsulated member 200 .
- the height of the indented divider 220 is shown to be approximately half the height of the other filled portions 230 , other height ratios are possible. In one embodiment, the ratio of the height of the indented divider 220 to the height of the other filled portions 230 may decrease proportionally as the height of the heel increases.
- the indented portion 220 may allow for a portion of an attached layer to protrude into the indented portion 220 , thereby reducing slippage and increasing the effectiveness of the encapsulated member 200 . In one embodiment, the indented portion 220 may be removed or omitted resulting in an encapsulated member 200 having a continuous volume of gel.
- FIG. 3A illustrates a classic high-heeled shoe 300 with a front portion 305 , a mid portion 310 , an end portion 315 , and a heel stake 320 .
- the mid portion 310 may be raised off the ground by the heel stake 320 , the latter of which may vary in height.
- Other portions of the shoe 300 which may hold the foot to the shoe e.g., shoe straps have been omitted for clarity.
- FIG. 3B illustrates a deconstructed view of the shoe 300 .
- the shoe 300 may include a top outer layer 330 which may be configured to rest upon a bottom structure 350 .
- the top outer layer 330 may include a front portion 335 for placement of the toes and the balls of the foot, a mid portion 340 for placement of the arch or “middle” of the foot, and an end portion 345 for placement of the heel of the foot.
- the top outer layer 330 may be attached on top of the bottom structure 350 when the shoe 300 is fully constructed.
- the bottom structure 350 may include a front portion 355 , a mid portion 360 , and an end portion 365 which correspond directly and may be in physical contact with the front portion 335 , the mid portion 340 , and the end portion 345 of the top outer layer 330 , respectively.
- the bottom structure 350 may include a thick, rigid base 375 at the front portion 355 .
- the rigid base 375 may include a front lip 380 about the perimeter of the front portion 355 .
- the front lip 380 may be configured to hold the front portion 335 of the top outer layer 330 in place when the shoe 300 is fully constructed.
- the rigid base 375 may also include a cavity towards the center of the rigid base 375 for holding the encapsulated member 370 .
- the rigid base 375 may be constructed out of a hard polymer or plastic and may be configured to support and withstand several hundred pounds of human weight without breaking.
- the rigid base 375 may be configured to form a continuous, rigid border around the edges of the encapsulated member 370 .
- the rigid base 375 may form a border of at least three-sixteenth of an inch, but the border may increase to over half an inch in some embodiments.
- the border might not be uniform in width surrounding the encapsulated member 370 .
- the border may be formed by cutting out a portion of the rigid base 375 or forming the rigid base 375 with a cavity for the encapsulated member 370 . In this manner, the encapsulated member 370 may be held in place and localized in the front portion 355 of the bottom structure 350 .
- the mid portion 360 may be a thin, flexible structure for supporting the mid portion 340 of the top outer layer 330 .
- the mid portion 360 may be a thin piece of wood.
- Attached to the mid portion 360 is the end portion 365 of the bottom structure 350 .
- the heel stake 320 may be attached towards the center of the end portion 365 and raise the foot off the ground.
- FIG. 3C illustrates a further deconstructed view of the bottom structure 350 of shoe 300 .
- the encapsulated member 370 has been removed to better illustrate the cavity 397 .

- the top of the encapsulated member 370 may protrude out of the cavity 397 .
- a high-heeled shoe 400 is illustrated with a front portion 405 , a mid portion 410 , an end portion 415 , and a heel stake 420 .
- the mid portion 410 may be raised off the ground by the heel stake 420 , the latter of which may vary in height.
- Other portions of the shoe that hold the foot to the shoe e.g., shoe straps have been omitted for clarity.
- FIG. 4B is a deconstructed view of the shoe 400 , and in particular, the top rigid layer 430 of the shoe 400 .
- the top rigid layer 430 may sit on top of (and be attached to) bottom liner layer 450 of FIG. 4C .
- the top rigid layer 430 may include a front portion 435 for placement of the toes and the balls of the foot, a mid portion 440 for placement of the arch or “middle” of the foot, and an end portion 445 for placement of the heel of the foot.

- the top rigid layer 430 may be a polymer wrapped with a soft vinyl or leather outer surface.
- the top rigid layer 430 may also include an encapsulated member 470 (e.g., encapsulated member 200 ) embedded inside of the front portion 435 of the top rigid layer 430 . While not shown, the encapsulated member 470 may sit within a cavity (e.g., similarly to encapsulated member 170 and 370 ). As shown by the dotted border, the encapsulated member 470 may be located within a central portion of the front portion 435 , and may be surrounded laterally and underneath by a rigid structure having a durometer rating higher than the encapsulated member 470 . In addition, the encapsulated member 470 may be covered with soft vinyl or leather.

Abstract
Devices, methods, and systems discussed herein relate to a high-heeled shoe; and more particularly, for providing improved comfort and/or to alleviate foot pain related to the wearing of a high-heeled shoe. For example, a high-heeled shoe may include an insole or a top outer layer and a bottom rigid structure. The bottom rigid structure may include a front portion, a mid portion, and an end portion. The front portion of the bottom rigid structure may include a cavity or cut-out portion for insertion of an encapsulated gel. When the shoe is worn, the encapsulated gel may expand laterally in response to an introduction of pressure on a top surface of the encapsulated gel thereby dispersing pressure on the balls of the foot.

- The present invention relates to a device, method, and/or system for alleviating pressure, soreness, or pain to a person's foot resulting from the person wearing a high-heeled shoe.
- 2. Description of Related Art
- A woman's high-heeled shoe, commonly known as “high-heels” or just “heels”, is a vital part of any woman's shoe collection. Traditional high-heels are virtually the only accepted form of footwear for a woman attending a formal or professional event. However, because high-heels have evolved and become more popular as a fashion statement, “pumps”, “stilettos”, “wedges”, and other types of casual high-heeled shoes have also achieved significant success in the marketplace.
- Despite the increased popularity of high-heels and variations thereof, at least one major drawback remains. In contrast to flat-soled shoes such as sneakers or sandals where the weight of a woman's body is spread out over the entire foot, high-heeled shoes require that a woman carry more or most of her weight on the balls of her foot, thereby focusing significant pressure on the front area of the foot. For example, for flat, non-high-heeled shoes, less than 50% of the person's weight is distributed over the balls of the person's foot. However, for high-heeled shoes having at least a two-inch heel, over 70% of the person's weight may be borne by the balls of the person's foot, which is an increase of over 20%. Such discomfort may be further exacerbated as a result of the height of the heels, which elevate the person in the heel or calcaneus area of the foot. As heel height increases, the percentage of a person's weight borne by the balls of the foot also increases. The medical issues that may arise from wearing high-heels are not limited to pain in the front area of the foot, but may extend to other areas of the foot, ankle, knee, hip, and even the person's back. Moreover, high-heels may significantly alter a person's natural stance, posture, and/or gait. Not surprisingly, women commonly report pain or discomfort after walking in high-heels. However, for most women, the price of discomfort is still worth the benefits of wearing high-heels.
- The structural differences between flat-heeled and high-heeled shoes are also very significant. For example, flat-heeled shoes such as sneakers allow greater flexibility and movement so that the wearer can pronate her feet. However, because high-heels are designed to increase a woman's height by slanting the foot forward and down while elevating the heel away from the ground, high-heels that are too flexible and unsupported may pose a risk of injury. Accordingly, a rigid structure may be beneficial to reduce foot, ankle, and other injuries.
- Because aesthetic appeal is typically the primary driving factor in the sale of high-heeled shoes, any advancement in high-heeled shoes must be designed with aesthetic appeal in mind. Moreover, because of the structural and stylistic elements peculiar to high-heels, advancements developed for other types of footwear (e.g., sneakers) cannot simply be imported and applied to high-heels. What is needed is a high-heeled shoe that minimizes discomfort without significantly restricting the design attributes of the high-heeled shoe.
- This Summary is included as to introduce, in an abbreviated form, various topics to be elaborated upon below in the Detailed Description. This Summary is not intended to identify key or essential aspects of the claimed invention. This Summary is similarly not intended for use as an aid in determining the scope of the claims.
- Devices, methods, and systems discussed herein relate to a high-heeled shoe and more particularly, for providing improved comfort and/or to alleviate foot pain related to the wearing of a high-heeled shoe.
- In one embodiment, a high-heeled shoe may include an insole or a top outer layer and a bottom rigid structure. The bottom rigid structure may include a front portion, a mid portion and an end portion. The front portion of the bottom rigid structure may include a cavity or cut-out portion for insertion of an encapsulated member. When the shoe is worn, the encapsulated member may expand laterally in response to an introduction of pressure on a top surface of the encapsulated member thereby dispersing pressure on the balls of the foot.
- In one embodiment, the cavity for the encapsulated member may be configured to contact one side of a foam layer, while the other side of the foam layer contacts a bottom surface of the encapsulated member. In other words, the foam layer may separate the surface of the cavity from a surface of the encapsulated member.
- In one embodiment, a high-heeled shoe may include a top rigid structure and a bottom layer. The top rigid structure may be shaped to have a raised end portion, a sloped mid portion and a substantially flat front portion. The top rigid structure may further include an embedded encapsulated member located within a cut-out or cavity of the top rigid structure. The bottom layer may include a flexible flat portion and a heel portion attached to a heel stake. The bottom layer may be attached to the top rigid structure such that the flexible flat portion may take the shape of the top rigid structure.

Throughout the drawings, reference numbers are re-used to indicate correspondence between referenced elements.
- As used herein, the terms “front portion”, “mid portion” and “end portion” are used to describe different portions of the shoe. In some embodiments, the front portion may correspond to the area of the shoe which contacts or corresponds with a “ball of the foot” or an area between the arch and the end of the toes—which may or might not include the toes themselves. In some embodiments, the mid portion may correspond to the area of the shoe which contacts or corresponds with an arch of the foot. In some embodiments, the end portion may correspond to the area of the shoe which contacts or corresponds with a heel of the foot. Accordingly, “front portion” may be used interchangeably with “ball portion”, “mid portion” may be used interchangeably with “arch portion” and “end portion” may be used interchangeably with “heel portion”. Furthermore, as used herein, the term “rigid” includes, but is not limited to, different degrees of rigidity from semi-rigid (e.g., a durometer of 80) to very rigid (e.g., a durometer of 115), but preferably is within a durometer range of between about 80-115, and more preferably is within a durometer range of between about 90-105.

FIG. 1A illustrates a platform high-heeled shoe 100 with afront portion 105, amid portion 110, anend portion 115 and aheel portion 120. Other portions of the shoe that hold the foot to the shoe (e.g., shoe straps) have been omitted for clarity. While theshoe 100 is illustrated to have a heel length of over two inches, the heel length may vary. The heel length may be defined as the difference between the height of the heel raised above the ground and the height of the toes raised above the ground. As the heel length increases, the slope of themid portion 110 and theend portion 115 may also increase. -
FIG. 1B illustrates a deconstructed view of theshoe 100. Theshoe 100 may include a topouter layer 130 which may be a flat, thin platform for the foot to rest upon. The topouter layer 130 may include afront portion 135 for placement of the toes and the balls of the foot, amid portion 140 for placement of the arch or “middle” of the foot, and anend portion 145 for placement of the heel of the foot. The topouter layer 130 may be attached on top of a bottomrigid structure 150 when theshoe 100 is fully constructed. The bottomrigid structure 150 may include afront portion 155, amid portion 160, and anend portion 165 which correspond directly and may be in physical contact with thefront portion 135, themid portion 140, and theend portion 145 of the topouter layer 130, respectively. The bottomrigid structure 150 may include arigid base 175 constructed out of a hard polymer or plastic and may be configured to support and withstand several hundred pounds of human weight without breaking. In one embodiment, therigid base 175 may be non-flexible (e.g., not capable of bending). Therigid base 175 may span thefront portion 155, themid portion 160 and theend portion 165 of the bottomrigid structure 150. An encapsulatedmember 170 may be inserted into therigid base 175. Therigid base 175 may be configured to form a continuous, rigid border around the edges of the encapsulatedmember 170. For example, therigid base 175 may form a border of at least three-sixteenth of an inch, but the border may increase to over half an inch in some embodiments. The border might not be uniform in width surrounding the encapsulatedmember 170. In one embodiment, the border may be formed by cutting out a portion of therigid base 175 or forming therigid base 175 with a cavity for the encapsulatedmember 170. In this manner, the encapsulatedmember 170 may be held in place and localized only in thefront portion 155 of the bottomrigid structure 150. For design purposes, anouter layer 180 may surround the outside edges of therigid base 175. In one embodiment,several holes rigid base 175 which may allow theshoe 100 to minimally flex, thereby preventing theshoe 100 from cracking when a large amount of pressure is exerted on theshoe 100 by the wearer's weight. Theholes holes mid portion 160 and theend portion 165 and may be orthogonal to the surface upon which theshoe 100 is resting. As themid portion 160 and theend portion 165 may be sloped, theholes mid portion 160 and theend portion 165. -
FIG. 1C illustrates a further deconstructed view of the bottomrigid structure 150 of theshoe 100. As shown, the encapsulatedmember 170 has been removed to better illustrate thecavity 197. In addition, an optionalthin foam layer 195 is shown in thecavity 197. Thecavity 197 may be formed by a continuous smooth wall substantially similar in shape as thethin foam layer 195 and the encapsulatedmember 170. Thecavity 197 may have a depth slightly less than the thickness of a combination of thethin foam layer 195 and the encapsulatedmember 170. In other words, when the encapsulatedmember 170 is positioned inside thecavity 197, the top of the encapsulatedmember 170 may protrude out of thecavity 197. Accordingly, when thetop layer 130 is affixed to the bottomrigid structure 150, the encapsulatedmember 170 may slightly bulge and press into thetop layer 130. -
FIG. 1D illustrates an exploded view of theshoe 100. As shown, the topouter layer 130 may cover the bottomrigid structure 150 when the encapsulatedmember 170 is inserted into thecavity 197 of the bottomrigid structure 150. -
FIG. 1E illustrates a side view of theshoe 100 with a cross sectional view of thefront portion 155. As shown, the encapsulatedmember 170 may be located in and/or fixed to one or more walls of the bottomrigid structure 150 forming thecavity 197. As shown, the top of the encapsulatedmember 170 may protrude out of thecavity 197. -
FIG. 2A illustrates a perspective view of the encapsulatedmember 200, as isolated from theshoe 100. In the absence of an encapsulatedmember 200, pressure caused by walking on a high-heeled shoe is mostly re-absorbed by the balls of the foot since the structure of a high-heeled shoe is typically rigid and non-compliant, even if other layers or materials are included to cushion the foot. In contrast, the inclusion of the encapsulatedmember 200 operates to disperse pressure placed on the foot. The encapsulatedmember 200 may be constructed of an elastic membrane (e.g., a plastic) infused with a viscous fluid or gel. Alternatively, the encapsulatedmember 200 may be filled with air, water and/or any other appropriate substance. While any non-rigid substance may be utilized, a gel may be preferred. - As shown in
FIG. 2B , when a force is exerted on the filledportion 230 of the encapsulated member 200 (e.g., by a person stepping on the shoe), lateral displacement of the substance within the filledportion 230 may result. In so doing, the encapsulatedmember 200 enlarges the point of pressure on the balls of the foot. Pressure caused by walking on the high-heeled shoe is thereby dispersed over a larger area (i.e., over the surface area of the encapsulated member 200) instead of being focused and directed on one small point. As a result, the foot may feel reduced pressure and the wearer may be able to walk a longer duration before feeling any discomfort. In one embodiment, by having the encapsulatedmember 200 at the front portion of theshoe 100, the encapsulatedmember 200 does not suffer from increased internal pressure resulting from too large of a surface area. - In one embodiment, the encapsulated
member 200 may be asymmetrically formed. Alternatively, the encapsulatedmember 200 may be configured to be symmetrical and may be a geometric (e.g., square, rectangular, triangular, trapezoidal, etc.) or non-geometric shape (e.g., shaped to mimic the footprint of a typical foot). In one embodiment, the encapsulatedmember 200 may have an enlargedflat base 205 including acontinuous flange portion 225 about the perimeter. Thecontinuous flange portion 225 is about one-eighths of an inch wide. However, any width (e.g., between one-sixteenth of an inch to a half of an inch) may be possible. As viewed inFIG. 2B , thecontinuous flange portion 225 is relatively thin compared to the actual thickness of the filledportion 230. Thecontinuous flange portion 225 may function to create a space between the encapsulatedmember 200 and the cavity in which the encapsulatedmember 200 sits. This space allows the encapsulatedmember 200 to laterally expand without leaking or otherwise losing efficacy when pressure is exerted on a top surface of the encapsulatedmember 200. Thecontinuous flange portion 225 may also serve to ensure that the encapsulatedmember 200 is fixed to one position and does not move about the cavity (e.g., cavity 197). An optional adhesive may be used to further fix the encapsulatedmember 200 to thecavity 197. However, an adhesive alone might not be as effective without thecontinuous flange portion 225 or might not function for a long enough duration. In one embodiment, the encapsulatedmember 200 may further include atop portion 210 and abottom portion 215 separated by anindented portion 220. - In one embodiment, the encapsulated
member 200 may have a flat base without any flanges (not shown). In other words, the surface area of the top surface and the surface area of the bottom surface may be equal. -
FIG. 2C is a side view of the encapsulatedmember 200. Although the height of theindented divider 220 is shown to be approximately half the height of the other filledportions 230, other height ratios are possible. In one embodiment, the ratio of the height of theindented divider 220 to the height of the other filledportions 230 may decrease proportionally as the height of the heel increases. Theindented portion 220 may allow for a portion of an attached layer to protrude into theindented portion 220, thereby reducing slippage and increasing the effectiveness of the encapsulatedmember 200. In one embodiment, theindented portion 220 may be removed or omitted resulting in an encapsulatedmember 200 having a continuous volume of gel. -
FIG. 3A illustrates a classic high-heeled shoe 300 with afront portion 305, amid portion 310, anend portion 315, and aheel stake 320. As shown, themid portion 310 may be raised off the ground by theheel stake 320, the latter of which may vary in height. Other portions of theshoe 300 which may hold the foot to the shoe (e.g., shoe straps) have been omitted for clarity. -
FIG. 3B illustrates a deconstructed view of theshoe 300. Theshoe 300 may include a topouter layer 330 which may be configured to rest upon abottom structure 350. The topouter layer 330 may include afront portion 335 for placement of the toes and the balls of the foot, amid portion 340 for placement of the arch or “middle” of the foot, and anend portion 345 for placement of the heel of the foot. The topouter layer 330 may be attached on top of thebottom structure 350 when theshoe 300 is fully constructed. Thebottom structure 350 may include afront portion 355, amid portion 360, and anend portion 365 which correspond directly and may be in physical contact with thefront portion 335, themid portion 340, and theend portion 345 of the topouter layer 330, respectively. Thebottom structure 350 may include a thick,rigid base 375 at thefront portion 355. Therigid base 375 may include afront lip 380 about the perimeter of thefront portion 355. Thefront lip 380 may be configured to hold thefront portion 335 of the topouter layer 330 in place when theshoe 300 is fully constructed. Therigid base 375 may also include a cavity towards the center of therigid base 375 for holding the encapsulatedmember 370. In one embodiment, therigid base 375 may be constructed out of a hard polymer or plastic and may be configured to support and withstand several hundred pounds of human weight without breaking. Therigid base 375 may be configured to form a continuous, rigid border around the edges of the encapsulatedmember 370. For example, therigid base 375 may form a border of at least three-sixteenth of an inch, but the border may increase to over half an inch in some embodiments. The border might not be uniform in width surrounding the encapsulatedmember 370. In one embodiment, the border may be formed by cutting out a portion of therigid base 375 or forming therigid base 375 with a cavity for the encapsulatedmember 370. In this manner, the encapsulatedmember 370 may be held in place and localized in thefront portion 355 of thebottom structure 350. - Attached to the
rigid base 375 is themid portion 360. Themid portion 360 may be a thin, flexible structure for supporting themid portion 340 of the topouter layer 330. In one embodiment, themid portion 360 may be a thin piece of wood. Attached to themid portion 360 is theend portion 365 of thebottom structure 350. Theheel stake 320 may be attached towards the center of theend portion 365 and raise the foot off the ground. -
FIG. 3C illustrates a further deconstructed view of thebottom structure 350 ofshoe 300. As shown, the encapsulatedmember 370 has been removed to better illustrate thecavity 397. In addition, anoptional foam layer 395 is shown remaining in thecavity 397. Thecavity 397 may be formed by a continuous smooth wall substantially similar in shape as thefoam layer 395 and the encapsulatedmember 370. Thecavity 397 may have a depth slightly smaller than a thickness of the combination of thethin foam layer 395 and the encapsulatedmember 370. In other words, when the encapsulatedmember 370 is positioned inside thecavity 397, the top of the encapsulatedmember 370 may protrude out of thecavity 397. In one embodiment, encapsulatedmember 370 may be the encapsulatedmember 200 as discussed above with respect toFIGS. 2A-2C . -
FIG. 3D illustrates an exploded view of theshoe 300. As shown, the topouter layer 330 may cover thebottom structure 350 when encapsulatedmember 370 is inserted into thecavity 397 of thebottom structure 350. -
FIG. 3E illustrates a side view of theshoe 300 with a cross sectional view of thefront portion 355. As shown, the encapsulatedmember 370 may be located in and/or fixed to one or more walls of the bottomrigid structure 350 forming thecavity 397. As shown, the top of the encapsulatedmember 370 may protrude out of thecavity 397. - Turning to
FIG. 4A , a high-heeled shoe 400 is illustrated with afront portion 405, amid portion 410, anend portion 415, and aheel stake 420. As shown, themid portion 410 may be raised off the ground by theheel stake 420, the latter of which may vary in height. Other portions of the shoe that hold the foot to the shoe (e.g., shoe straps) have been omitted for clarity. -
FIG. 4B is a deconstructed view of theshoe 400, and in particular, the toprigid layer 430 of theshoe 400. The toprigid layer 430 may sit on top of (and be attached to)bottom liner layer 450 ofFIG. 4C . The toprigid layer 430 may include afront portion 435 for placement of the toes and the balls of the foot, amid portion 440 for placement of the arch or “middle” of the foot, and anend portion 445 for placement of the heel of the foot. As shown, the structure of the toprigid layer 430 may be flat at thefront portion 435 and slope upwards when moving from thefront portion 435 to theend portion 445. The toprigid layer 430 may be a polymer wrapped with a soft vinyl or leather outer surface. Additional inserts such as a suede lining may be added. The toprigid layer 430 may also include an encapsulated member 470 (e.g., encapsulated member 200) embedded inside of thefront portion 435 of the toprigid layer 430. While not shown, the encapsulatedmember 470 may sit within a cavity (e.g., similarly to encapsulatedmember 170 and 370). As shown by the dotted border, the encapsulatedmember 470 may be located within a central portion of thefront portion 435, and may be surrounded laterally and underneath by a rigid structure having a durometer rating higher than the encapsulatedmember 470. In addition, the encapsulatedmember 470 may be covered with soft vinyl or leather. Because the soft vinyl or leather covering is not rigid, the encapsulatedmember 470 may absorb and disperse pressure when the balls of the foot press against the toprigid layer 430. -
FIG. 4C illustrates thebottom liner layer 450. Thebottom liner layer 450 may include aflexible portion 455, arigid portion 460, and aheel stake 420. Theflexible portion 455 may be thin and constructed out of a dense foam or elastic polymer. Theflexible portion 455 may correspond with and span thefront portion 435 of the toprigid layer 430 and themid portion 440 of the toprigid layer 430. Theflexible portion 455 may also be attached to theheel stake 420 in a tapered manner along side a flat length of theheel stake 420. Theflexible portion 455 may be configured to take the shape of the toprigid layer 430 when attached to the toprigid layer 430 and further support the attachment of theheel stake 420 to theend portion 445 of the toprigid layer 430. -
FIG. 4D illustrates an exploded view of the shoe ofFIG. 4A-4C . As shown, toprigid layer 430 may include an encapsulatedmember 470 embedded within a top layer and a bottomrigid layer 495 fixed to or sitting within acavity 497 of the bottomrigid layer 495. The toprigid layer 430 may be attached to theheel stake 420 and theflexible portion 455. -
FIG. 4E illustrates a side view of theshoe 400 with a cross sectional view of thefront portion 455. As shown, the encapsulatedmember 470 may be located in and/or fixed to one or more walls of the toprigid layer 430 forming thecavity 497. -
FIG. 5A illustrates an embodiment of a high-heeled boot 500 having afront portion 505, amid portion 510, anend portion 515, and aheel stake 520.FIG. 5B illustrates a close-up, cross-sectional view of afront portion 505 of the high-heeled boot 500 ofFIG. 5A . As shown, the insole of thefront portion 505 may include a first lining layer 530 followed by afoam layer 535, and then a rigidstructural layer 575 with an encapsulatedmember 570. The first lining layer 530 may be configured to be a thin upper membrane configured to contact the foot (or sock). The membrane may be any suitable material including suede, vinyl, leather, and the like. Thefoam 535 may be configured to take the form of the user's foot when pressure from the foot is transferred to the foam 535 (e.g., “memory” foam). The rigidstructural layer 575 may be similar to therigid base member 570. As the layers of material between the foot and the encapsulatedmember 570 are all compliant and relatively thin, the pressure (and force) from the foot is still transferred to the encapsulatedmember 570 for dispersal. -
FIG. 6 illustrates a view of a high-heeled shoe 600 showing the different geometric planes therein in accordance with one or more embodiments described herein. The geometric planes illustrated with respect to theshoe 600 may be applicable to any high heeled shoe discussed herein. As shown, theshoe 600 may be divided into a front or “balls”portion 605 being defined by or lying along afirst plane 655, a mid orarch portion 610 being defined by or lying along asecond plane 660 and an end orheel portion 615 being defined by or lying along athird plane 665. Thefirst plane 655 may lie along a substantially flat surface of thefront portion 605 and have a slope of zero or close to zero. Thesecond plane 660 may lie along a substantially flat surface of themid portion 610 and have a slope greater than the slope of thefirst plane 655. In one embodiment, the angle created between thefirst plane 655 and thesecond plane 660 is between 90 degrees and 150 degrees, but preferably between 115 degrees and 135 degrees. Thethird plane 665 may lie along a substantial flat surface of theend portion 615 and may have a slope equal to or less than thesecond plane 660.
