DETAILED DESCRIPTION

Reference now will be made to the embodiments of the invention, one or more examples of which are set forth below. Each example is provided by way of explanation of the invention, not as a limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in this invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used on another embodiment to yield a still further embodiment. Thus, it is intended that the present invention cover such modifications and variations as come within the scope of the appended claims and their equivalents. Other objects, features, and aspects of the present invention are disclosed in or are apparent from the following detailed description.
The present invention is directed to an athletic shoe with a uniquely effective cleat configuration. The present invention provides improved traction and support for athletic activities. While the present invention is particularly well suited for a baseball shoe, it could be utilized for athletic shoes in football, rugby, golf, and many other sports.
The present invention is adapted to advantageously provide traction for forward and lateral movement by focusing on areas of the foot where such movement originates and is supported. The bone structure of the foot is important in determining the pressure points of the shoe where the wearer's weight is applied. Very generally, weight is projected between the forefoot, midfoot and heel regions of the foot. The forefoot includes the toe region of the foot. As used herein, medial refers to the inside of the wearer's foot and lateral refers to the outside of the wearer's foot. The present invention achieves greatly improved traction and support by focusing cleat placement to the regions of the foot where forward and lateral movement originate and are supported.
Generally, a cleat is a projection from the bottom of a shoe (or outsole) that provides added traction. The cleats of the present invention can be made of thermoplastic polyurethane (TPU), metal, rubber or any other material as will be understood by one of ordinary skill in the art using the teachings disclosed herein. The cleats may be molded from the same material as the sole of the athletic shoe or may be secured to the sole by glue or some other method known to one of ordinary skill in the art. Cleats vary greatly in height and width depending on their location and their intended purpose. Cleats may also have one or more colors that are the same as or differ from one another. Cleat color may also differ from the color of the outsole and/or soleplate. In addition, a textured surface or other features may be added to provide a non-slip surface on the ground-engaging portion of the cleat.
With reference to FIG. 1 and FIG. 2, an exemplary embodiment of a cleat configuration for an athletic shoe is provided. The athletic shoe 100 has an outsole 10 with a unique cleat configuration. The outsole 10 is made up of a forefoot region 20, a midfoot region 40, and a heel region 60. The outsole 10 of the present invention can be made of thermoplastic polyurethane (TPU), rubber, polyurethane (PU) or any other material as will be understood by one of ordinary skill in the art using the teachings disclosed herein. The outsole may either be the same color or a different color from the cleats and/or soleplate. The outsole 10 has a front end 12, a rear end 13, a medial side 14, a lateral side 16, and a centerline 24. In addition, the outsole is defined by a perimeter 18.
In one exemplary embodiment, one or more forefoot cleats 22 are positioned in the forefoot region 20 of the outsole 10. The forefoot cleats 22 are positioned to optimize take off and braking power by utilizing the weight on the forefoot region 20 during these actions. As illustrated in FIG. 1 and FIG. 2, the forefoot cleats 22 are positioned along the shared area of the perimeter 18 of the outsole 10 and the forefoot region 20. However, in some embodiments, the forefoot cleats 22 may also be located closer to the centerline 24. The forefoot cleats 22 are approximately equal in size and have a base 38 with a length that is greater than the width and a front end 28 and a rear end 30 (FIG. 1). In other exemplary embodiments, the forefoot cleats 22 may have varying size and shape.
As illustrated in FIG. 1 and FIG. 2, for each forefoot cleat 22 positioned on the medial side 14 of the outsole 10, there is a corresponding forefoot cleat 32 that is adjacently located on the lateral side 16 of the outsole 10. The front ends 28 of adjacently located forefoot cleats 22 and 32 are angled towards one another in a manner such that the distance between the front ends 28 is less than the distance between the rear ends 30. In addition, the adjacently located forefoot cleats 22, 32 are each approximately the same distance from the front end 12 of the outsole 10. In other exemplary embodiments, the adjacently located forefoot cleats 22, 32 may be at greater or lesser angles to one another than as shown in FIG. 1 and FIG. 2.
A toe cleat 21 is positioned in the forefoot region 20 of the outsole 10. As illustrated in FIG. 1 and FIG. 2, the toe cleat 21 is positioned along the front end 12 of the outsole 10 in the forefoot region 20.
One or more midfoot cleats 42 are positioned in the midfoot region 40 of the outsole 10. The midfoot cleats 42 are located to provide for improved side-to-side control during lateral movements. The midfoot cleats 42 are positioned along the shared area of the perimeter 18 of the outsole 10 and the midfoot region 40. The midfoot cleats 42 are approximately equal in size and have a base 58 with a length that is greater than the width and a front end 48 and a rear end 50. In other exemplary embodiments, the midfoot cleats 42 may have varying size and shape.
As shown in FIG. 1 and FIG. 2, for each midfoot cleat 42 positioned on the medial side 14 of the outsole 10, there is a corresponding midfoot cleat 52 that is adjacently located on the lateral side 16 of the outsole 10. The front ends 48 of the adjacently located midfoot cleats 42, 52 are angled towards one another in a manner such that the distance between the front ends 48 is less than the distance between the rear ends 50. However, the adjacently located midfoot cleat 42, 52 are angled towards one another less than the adjacently located forefoot cleats 22, 32. In other exemplary embodiments, the adjacently located forefoot cleats 42, 52 may be at greater or lesser angles.
Also as illustrated in FIG. 1 and FIG. 2, additional adjacently located midfoot cleats 44, 45 are located closer to the centerline 24 in the midfoot region 40 of the outsole 10. Similar to the adjacently located midfoot cleats 42, 52, they are angled towards one another less than the adjacently located forefoot cleats 22, 32.
Thus, the adjacently located forefoot cleats 22, 32 function more effectively during acceleration and braking due to their greater angle towards one another. Similarly, the adjacently located midfoot cleats 42, 52, are angled towards one another less and are therefore more effective for lateral control.
Combined, the forefoot cleats 22 and midfoot cleats 42 make up perimeter cleats 80. The perimeter cleats 80 allow for optimal heel to toe transition and cleat pressure distribution. The perimeter cleats 80 benefit from the combined advantages of advanced take-off and breaking of the forefoot cleats 22 and improved lateral control of the midfoot cleats 42.
During the play of certain sports activities, it is not uncommon to encounter muddy, slippery surfaces. Mud separator cleats 82 help to increase traction as well as improve maneuverability during play. In yet another exemplary embodiment as illustrated in FIG. 1 and FIG. 2, one or more mud separator cleats 82 are positioned in the forefoot region 20 as well as the midfoot region 40. The mud separator cleats 82 are spaced so as to prevent or minimize mud from sticking on the outsole 10.
A pair of heel cleats 62 is positioned in the heel region 62 of the outsole 10. The heel cleats 62 are located to allow for superior take off and braking power by utilizing the weight on the heel region 60 during these actions. The heel cleats 62 are positioned along the shared area of the perimeter 18 of the outsole 10 and the heel region 60. The heel cleats 62 are equal in size and have a base 78 with a length that is greater than the width and a front end 68 and a rear end 70. In other exemplary embodiments, the heel cleats 62 may have varying size and shape.
As depicted in FIG. 1 and FIG. 2, one heel cleat 63 is positioned on the medial side 14 of the outsole 10, and there is a corresponding heel cleat 65 that is adjacently located on the lateral side 16 of the outsole 10. The front ends 68 are angled away from one another in a manner such that the distance between the front ends 68 is greater than the distance between the rear ends 70.
Another pair of heel cleats 66 is positioned at the portion of the heel region 60 closest to the front end 12 of the outsole 10 along the shared area of the perimeter 18 of the outsole 10 and the heel region 60. The second pair of heel cleats 66 is similar to the first pair 62, except it is arranged so that the distance between the front ends is less than the distance between the rear ends.
Each forefoot cleat 22, midfoot cleat 42, heel cleet 60, and mud separator cleat 82 has a ground-engaging surface 54 as illustrated in FIG. 1 and FIG. 2. The ground-engaging surface 54 (FIG. 1) is substantially flat and parallelogram shaped. However, the ground-engaging surface could also be textured and have varying shapes and sizes as would be known in the art. Also, each individual cleat may have a different type of ground-engaging surface. In some embodiments, notches 56 may be removed at the intersection of the two sides of the parallelogram shaped ground-engaging surface 34. At these notches 56, the ground-engaging surface 54 is not flat. In addition, in other exemplary embodiments, other suitable shapes and features may be added to the ground-engaging surface 54.
A sole plate 84 is illustrated in FIG. 1 and FIG. 2. The sole plate 84 is a layer of material above the outsole 10 and may be formed from thermoplastic polyurethane (TPU), rubber, polyurethane (PU) or any other material as will be understood by one of ordinary skill in the art using the teachings disclosed herein. The sole plate 84 provides additional support to the wearer of the shoe by enhancing the stability of the outsole. As illustrated in FIG. 1 and FIG. 2, the sole plate 84 is positioned along the heel region 60, as well as the midfoot region 40 and the forefoot region 20. The sole plate 84 is at the base of the heel cleats 62 and perimeter cleats 80. The sole plate may be a different color from the cleats and/or outsole. In addition, in other exemplary embodiments, the sole plate 84 may have other suitable shapes and features.
As illustrated in FIG. 1 and FIG. 2, the sole plate 84 also surrounds a clear bubble 86. The bubble 86 is formed from PU or any other suitable material and is the substantially level with the outsole 10. The bubble 86 may contain information about the footwear or other indicia.
While exemplary embodiments of the present invention have been described utilizing various cleat configurations, it should be understood that the present invention is not limited to only these configurations as will be understood by one of ordinary skill in the art using the teaching disclosed herein. It should be appreciated by those skilled in the art that modifications and variations can be made to the exemplary embodiment of athletic shoe 10 as described herein, without departing from the scope and spirit of the claims. It is intended that the invention include such modifications and variations as come within the scope of the appended claims and their equivalents.
