The present invention is directed to an athletic shoe with a uniquely effective cleat arrangement. 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 to the foot between the rearfoot and the forefoot. The forefoot is comprised of the lesser tarsus and five major bones referred to as the first, second, third, fourth, and fifth metatarsal. Of the weight carried by the forefoot, much of the weight is transferred to the first and fifth metatarsal areas 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 first and fifth metatarsal areas of the foot.
With reference to
In one exemplary embodiment of the present invention, cleats are positioned at the first metatarsal region 12 of the athletic shoe 10. Cleats 6 and 7 are configured to form a v-shape and comprise a v-cleat 14, also referred to as an acute angled cleat. It should be understood that the present invention is not limited to the precise v-shape shown in the figures; instead, multiple cleat configurations fall within the claims as set forth below and as will be understood by one of ordinary skill in the art. The v-cleat 14 has generally oval-shaped ground-engaging surfaces 16. The ground-engaging surfaces 20 have a front end 8 and a rear end 5. In the exemplary embodiment of
The v-cleat 14 improves traction and directional response for the wearer of the athletic shoe 10. The initial movement from a stationary position involves establishing traction for pushing off with the foot. To maximize the amount of traction, it is important to position cleats on the shoe based, in part, upon the bone structure of the foot. The unique shape of the v-cleat 14 surrounds the bottom portion 13 of the first metatarsal region 12 allowing the wearer more traction and stability. The v-cleat 14 allows optimal traction for the wearer during both forward pushoff, as the wearer begins running or fielding, and also at slowdown as the wearer comes to a stop or breaks his run. As the wearer's weight is largely retained over the first metatarsal region of the shoe, the v-cleat 14 provides optimal control. In addition, the v-cleat 14 allows for better cutting or direction of run change to the wearer. These advantages are provided because of the shape and orientation of the v-cleat 14, which acts as a wedge against the ground or other surface.
A first toe cleat 22 and second toe cleat 26 are positioned proximate to one another near the top portion 21 of the first metatarsal region 12 of the athletic shoe 10. The toe cleats increase traction for forward movement for the wearer of the athletic shoe 10. The first toe cleat 22 and second toe cleat 26 each have a generally oval-shaped ground-engaging surfaces 24 and 28. The ground-engaging surface 24 of the first toe cleat 22 has a front 27 and rear 29. The ground-engaging surface 28 of the second toe cleat 26 has a front 23 and rear 25. The second toe cleat ground-engaging surface 28 is positioned closer to the top portion 21 of the first metatarsal region 12 of the athletic shoe 10 than the second toe cleat ground-engaging surface 28 and the first toe cleat ground-engaging surface 24 and the second toe cleat ground-engaging surface 28 are angled towards one another in a manner such that the front ends 27, 23 of the ground-engaging surfaces are closer together than the rear ends 29, 25. The toe cleats 22, 26 provide the wearer with quicker and more positive starting power. Maximum traction for an initial burst of acceleration by the wearer is optimally achieved by the added resistance provided by the toe cleats 22, 26 during the rearward push with the athletic shoe 10.
A medial cleat 18 is positioned between the top portion 21 and bottom portion 13 of the first metatarsal region 12 of the athletic shoe 10, adjacent to the medial side 9 of the athletic shoe 10. The medial cleat 18 is positioned to provide optimal support and cornering for the wearer of the athletic shoe 10. The medial cleat 18 provides optimum traction for the variation of directional movements of the wearer. During sideward movement, the medial cleat 18 helps prevent the wearer's foot from rolling and allows full sideward movement by utilizing the shifting weight pattern of the foot. The medial cleat 18 has a generally triangular shaped ground-engaging surface 20.
The athletic shoe 10 includes a plurality of center-line cleats 75 positioned between the first metatarsal region 12 and the fifth metatarsal region 48 of the athletic shoe 10. The cleats 75 are generally positioned along a line extending from the middle portion 74 to the forefoot portion 39 of the athletic shoe 10 and are generally centered between the medial side 9 and lateral side 11 of the shoe.

Two cleats 51, 52 may be arranged in a manner to form an obtuse angle and to create an obtuse angled cleat 50. The obtuse angled cleat 50 has generally oval-shaped ground-engaging surfaces 53. The obtuse angled cleat 50 is positioned near the bottom portion 49 of the fifth metatarsal region 48 of the athletic shoe 10 with the open side 47 of the obtuse angled cleat 50 opening towards the medial side 9 of the athletic shoe 10. The obtuse angled cleat 50 is positioned to provide optimal support and cornering for the wearer of the athletic shoe 10. More specifically, obtuse angled cleat 50 is particularly beneficial in providing traction for lateral movement by the wearer.
A third toe cleat 40 is positioned near the top portion 37 of the fifth metatarsal region 48 of the athletic shoe 10. The third toe cleat 40 has a generally oval-shaped ground-engaging surface 42. The ground-engaging surface has a front 41 and rear 43. A lateral cleat 44 is positioned between the top portion 39 and bottom portion 49 of the fifth metatarsal region 48 of the athletic shoe 10 adjacent to the lateral side 11 athletic shoe 10. The front 41 of the ground-engaging surface 42 of the third toe cleat 40 is angled toward the lateral cleat 44. The lateral cleat 44 has a generally triangular shaped ground-engaging surface 45.
A fourth toe cleat 36 and fifth toe cleat 30 are positioned proximate to one another near the forefoot portion 39 of the athletic shoe 10. The fourth toe cleat 36 has a ground-engaging surface 38 and the fifth toe cleat 30 has a ground-engaging surface 32. A first heel cleat 54 and second heel cleat 60 are positioned near the heel portion 58 of the athletic shoe 10. The first heel cleat 54 has a ground-engaging surface 56 and the second heel cleat 60 has a ground-engaging surface 62. The ground-engaging surface 56 of the first heel cleat 54 has a front 55 and rear 57 and the ground-engaging surface 62 of the second heel cleat 60 has a front 61 and rear 63. The first heel cleat 54 and second heel cleat 60 are substantially symmetrically placed opposite one another with the first heel cleat 54 positioned at the lateral side 11 of the athletic shoe 10 and the second heel cleat 60 is positioned at the medial side 9 of the athletic shoe. The first heel cleat ground-engaging surface 56 and the second toe cleat ground-engaging surface 62 are angled towards one another in a manner such that the front ends 55, 61 of the ground-engaging surfaces 56,62 are farther apart than the rear ends 57,63.
A third heel cleat 66 and fourth heel cleat 64 are positioned near the heel portion 58 of the athletic shoe 10 between the middle portion 74 and heel portion 58 of the athletic shoe. The third heel cleat 66 has a ground-engaging surface 70 and the fourth heel cleat 64 has a ground-engaging surface 68. The ground-engaging surface 70 of the third heel cleat 66 has a front 67 and rear 69 and the ground-engaging surface 68 of the fourth heel cleat 64 has a front 71 and rear 73.
