DETAILED DESCRIPTION

Heel grip inserts and related methods are disclosed herein. In some embodiments, a heel grip insert may include first and second receptacles. The first receptacle may be to receive a heel of a foot, and may be defined by an under-foot portion, a back portion extending away from the under-foot portion, and opposing side portions joining the under-foot and back portions. The second receptacle may be to receive a heel collar of a shoe, and may be defined by the back portion and a lip portion, the lip portion angled away from the first receptacle.
Some embodiments of the heel grip inserts disclosed herein may provide an adhesive-free, anti-slip, molded fashion accessory heel grip. Some embodiments may be used in any of a number of different types of footwear, and may improve foot care by reducing foot slippage or other injury due to ill-fitting or slippery shoe interiors.
In the following detailed description, reference is made to the accompanying drawings that form a part hereof wherein like numerals designate like parts throughout, and in which is shown by way of illustration embodiments that may be practiced. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present disclosure.

FIGS. 1-3 are perspective views of a heel grip insert 100, in accordance with various embodiments. The heel grip insert 100 may include a first receptacle 102 and a second receptacle 104. The first receptacle 102 may be configured to receive a heel of a foot, and may be dimensioned appropriately. For example, the first receptacle 102 may be dimensioned to fit within an interior heel portion of a women's dress shoe (e.g., a flat or a pump). The first receptacle 102 may be defined by an under-foot portion 106, a back portion 110, and opposing side portions 108 a and 108 b joining the under-foot portion 106 and the back portion 110. The back portion 110 may extend away from the under-foot portion 106. The first receptacle 102 may have a first surface 124 oriented towards the wearer's heel when the wearer's heel is received in the first receptacle 102. The back portion 110 may include a reinforced portion 112, which may be thicker than the surrounding areas of the back portion 110 and/or may include an additional material to provide stiffening and/or cushioning. In some embodiments, the heel grip insert 100 may not offer additional support or cushion for a wearer's heel.
The second receptacle 104 may be configured to receive a heel collar of a shoe, and may be dimensioned appropriately. For example, the second receptacle 104 may be dimensioned to receive a heel collar of a women's dress shoe (e.g., a flat or a pump). The second receptacle 104 may be dimensioned to snugly secure a heel collar in the second receptacle 104. The second receptacle 104 may be defined by the back portion 110 and a lip portion 114. The lip portion 114 may be angled away from the first receptacle 102. In some embodiments, the lip portion 114 may be angled away from a wearer's leg when the wearer's heel is received in the first receptacle 102. The lip portion 114 may have a distal end 116, which may extend below the heel collar when the heel collar is received within the second receptacle 104. In some embodiments, the distal end 116 may extend less than one inch or less than one-half inch below the heel collar when the heel collar is received within the second receptacle 104.
The dimensions of the first receptacle 102 and the second receptacle 104 may be selected to conform to a wearer's heel and to the shape of the interior of a shoe. For example, in some embodiments, the side portions 108 a and 108 b and/or the back portion 110 may have regions of greater thickness that are positioned on either side of the wearer's heel below the ankle bone and at the back of the heel, where extra space often occurs in shoes that are slightly too large. In some embodiments, the dimensions of the heel grip insert 100 may be selected to conform to a wearer of a women's dress shoe, such as a pump or flat. In some embodiments, the first receptacle 102 may have a thickness of approximately 0.25 inches. In some embodiments, various portions of the first receptacle 102 (e.g., the back portion 110) may have a thickness between approximately 0.25 inches and 0.625 inches.
In some embodiments, the first receptacle 102 and the second receptacle 104 may be integrally formed as a single piece. For example, in some embodiments, the heel grip insert 100 may be injection molded. In some embodiments, the heel grip insert 100 may be formed from two or more materials. Examples of materials that may be used in the heel grip insert 100 may include, but are not limited to, rubber and/or rubber-like materials, neoprene, a rubber spray coating, foam molding compounds, plastic, nylon, and fiberglass. In some embodiments, the first receptacle 102 may be formed from two different materials. For example, the under-foot portion 106 may have a shoe facing surface 126 that may include neoprene or another especially non-slip or “grippy” material. The back portion 110 and/or the side portions 108 a and 108 b, which may embrace a wearer's heel, may be formed of a material similar to neoprene, though in some embodiments, a material that enhances “stickiness” may be preferred to maintain and improve contact with the wearer's skin for an extended duration. The lip portion 114 (and/or the embellishment object, discussed below) may be formed from one of the materials listed above, and may be coated, colored, dyed, or otherwise altered to enhance the appearance and detail. The lip portion 114 (and/or the embellishment object) may also consist of an alternative material, such as plastic, metal, wood, etc. In some embodiments, the materials selected for the first receptacle 102 and/or the second receptacle 104 may provide some flexibility so as to conform to a wearer's heel and/or the shape of the heel portion of a shoe.
In some embodiments, the first receptacle 102 and/or the second receptacle 104 may be formed from a rubber or rubber-like material. For example, one or more of the first receptacle 102 and the second receptacle 104 may be formed from neoprene. In some embodiments, the first surface 124 may have a “stickiness” to help secure the first receptacle 102 against the heel when the heel is received in the first receptacle 102. This stickiness may arise, for example, from a grip-providing texture (e.g., natural to the material of the first surface 124). In some embodiments, the heel grip insert 100 does not include an adhesive. In particular, some embodiments of the heel grip insert 100 may not use or rely on any adhesive to keep the heel grip insert 100 in place. Instead, the shape and thickness of the heel grip insert 100 may surround some or all (e.g., the majority) of a wearer's heel (e.g., including the sides, back, and under-foot area) and may fill in the extra space between a wearer's heel and the shoe, thereby reducing or avoiding foot slippage and/or blisters. When the first surface 124 of the first receptacle 102 is formed from a material with gripping properties, contact between the first surface 124 and the wearer's heel may create friction and reduce slipping. Thus, in some embodiments, no adhesive may be necessary or helpful to secure the heel grip insert 100 to a shoe, or to secure the heel grip insert 100 to the wearer's foot. Additionally, because the under-foot portion 106 of the heel grip insert 100 is positioned underneath a wearer's heel, the wearer's body weight and foot pressure also help secure the heel grip insert 100 within a shoe and against the wearer's foot.
FIGS. 4 and 5 are perspective views of the heel grip insert 100 of FIGS. 1-3 seated in a shoe 300, in accordance with various embodiments. As shown, the heel collar 302 of the shoe 300 may be received in the second receptacle 104 so that the heel collar 302 may be positioned between the lip portion 114 and the back portion 110. The back portion 110 may be positioned adjacent to a back heel surface of the shoe 300, the under-foot portion 106 may be positioned adjacent to a bottom surface of the shoe 300, and the side portions 108 a and 108 b may be positioned adjacent to side surfaces of the shoe 300. In use, the under-foot portion 106 may extend under a portion of a wearer's heel. In various embodiments, the under-foot portion 106 may extend under a portion of a wearer's heel for less than one inch, less than one-half inch, or less than one-quarter inch. In use, the side portions 108 a and 108 b may extend along the sides of a wearer's heel. In various embodiments, the side portions 108 a and 108 b may each extend along respective sides of a wearer's heel for less than two inches, less than one inch, less than one-half inch, or less than one-quarter inch.
In some embodiments, the lip portion 114 may include an embellishment object. An embellishment object may take the form of many different shapes or themes for different fashion styles. The embellishment object may include a variety of colors and textures to coordinate with a wearer's shoes or wardrobe (e.g., leather, plastic, metal, fabrics, etc.).
FIG. 6 is a perspective view of an embodiment of the heel grip insert 100 with a first embellishment object 118, and FIGS. 7 and 8 are perspective views of the heel grip insert 100 of FIG. 6 seated in the shoe 300, in accordance with various embodiments. In some embodiments, the embellishment object 118 may be positioned at least in part above the wearer's heel when the heel is received in the first receptacle 102. In some embodiments, the embellishment object 118 may be positioned at least in part above the heel collar 302 when the heel collar 302 is received in the second receptacle 104.
In some embodiments, the embellishment object 118 may be formed integrally with the lip portion 114. In some embodiments, the embellishment object 118 may be formed integrally with the back portion 110. In other embodiments, the embellishment object may be removably coupled, such as by a snap, hook-and-loop fastener, etc., such that it can be removed and replaced with another embellishment object and/or used on other footwear.
In some embodiments, an embellishment object may be a representation of a heart shape, wings, flower, bow, jewel, studs, spike, any sculptural shape that adds visual fashion embellishment, or any other decorative object, design, or pattern. For example, the embellishment object 118 may be a representation of a heart shape. In some embodiments, an embellishment object may be three-dimensional, and/or have three-dimensional detail.
In some embodiments, the heel grip insert 100 may have a coating (not shown) on the embellishment object 118. Such a coating may include paint, glitter, leather, fur, jewels, feathers, or one or more metallic elements, for example, but any suitable materials may be used for a coating on an embellishment object.
Any suitable decorative elements may be included in or provide the shape of an embellishment object. For example, FIG. 9 is a perspective view of an embodiment of the heel grip insert 100 with a second embellishment object 120, and FIGS. 10 and 11 are perspective views of the heel grip insert 100 of FIG. 9 seated in the shoe 300, in accordance with various embodiments. The embellishment object 120 may be a representation of a ribbon bow. FIGS. 12 and 13 are perspective views of an embodiment of the heel grip insert 100, with a third embellishment object 122, seated in the shoe 300, in accordance with various embodiments. The embellishment object 122 may be a representation of a patterned leaf. Any of the embodiments discussed above with reference to FIGS. 6-8 and/or to the embellishment object 118 may be applied to the embodiments of FIGS. 9-13 and the embellishment objects 120 and/or 122.
In some embodiments, the heel grip insert 100 may provide a fashion accessory that may be used and re-used by a wearer in a number of different shoes. Various embodiments of the heel grip insert 100 may provide the functionality of a molded, non-adhesive insert, the anti-slip ability of a heel grip, and the visual element of a fashion accessory (e.g., via the lip portion 114 and/or an embellishment object). In particular, some embodiments of the heel grip insert 100 may act as a heel grip by conforming to the shape of a wearer's heel and also the interior heel portion of a shoe (e.g., a pump or flat). Some embodiments of the heel grip insert 100 may act as a fashion accessory due to the heel grip insert 100 extending up the back of the wearer's heel and over the heel collar of the shoe, thereby providing a visible fashion element.
Various embodiments of the heel grip insert 100 (e.g., those that do not use an adhesive to secure the heel grip insert 100 to the shoe) may be easily removed from a shoe and used in multiple pairs of shoes to improve fit and comfort while adding a visible fashion element to change the look of any pair of shoes. This may provide wearers with more options and a more durable approach to improving the fit of shoes. A removable, reusable heel grip insert that provides heel gripping functionality and a visible fashion accessory may allow wearers to comfortably wear any pair of shoes and alter or enhance the appearance and style of their shoes.
Any suitable method may be used to manufacture the heel grip inserts disclosed herein (e.g., any of the embodiments of the heel grip insert 100).
