Abstract

An article of footwear in which certain regions of the upper may be slippery, such that it is more difficult for a person to firmly grasp the article of footwear. The eyestays in the article of footwear are biased towards the lateral side of the footwear. The article of footwear also has an outer sole with ridges at, for example, the back of the heel, the ball-of-the foot regions on the lateral and medial sides, respectively, of the article of footwear, and at the toe region. The ridges are angled downward, such that the wearer of the footwear may have increased traction by digging the ridges into the ground or into a playing surface.

First claim

What is claimed is:

1. An article of footwear comprising an upper and a sole attached to the upper,
wherein the upper comprises:
a toe region, a forefoot region, a midfoot region, and a heel region;
a lateral side and a medial side;
a first portion made of a first material with a first surface that has a first coefficient of friction;
a second portion made of a second material with a second surface that has a second coefficient of friction, wherein the second coefficient of friction is substantially greater than the first coefficient of friction;
a third portion made of a third material with a third surface that has a third coefficient of friction, wherein the second coefficient of friction is greater than the third coefficient of friction, wherein the third coefficient of friction is different than the first coefficient of friction;
an eyestay region comprising a plurality of eyelets, wherein the eyestay region is substantially biased towards the lateral side of the upper;
wherein the second portion is disposed between the first portion and the sole on the medial side;
wherein the third portion is a base layer that extends from the forefoot region to the eyestay region;

wherein the sole comprises:
a first elastomeric pad comprising a plurality of substantially concentric ridges that encircle a central region;
a textile material with a plurality of pads attached to the textile material, wherein the pads comprise downwardly-angled ridges at their outer edges; and
wherein the first elastomeric pad comprises a first aperture located in the central region for allowing moisture generated within the article of footwear to escape through the textile material and wherein a portion of the textile material is exposed through the first aperture.

2. The article of footwear of claim 1 , wherein the sole further comprises:
a heel region comprising a side portion and a lower portion, the lower portion being associated with a bottom surface of the sole, and the side portion being substantially perpendicular relative to the lower portion;
wherein an upwardly oriented surface includes a surface with a normal component that is oriented at least partially in an upwardly vertical direction, wherein a downwardly oriented surface includes a surface with a normal component that is oriented at least partially in a vertically downward direction; and
wherein the first elastomeric pad is disposed partially along the side portion, each of the plurality of substantially concentric ridges located on the side portion including a downwardly oriented surface and an upwardly oriented surface that meet at a peak portion, wherein the peak portion extends outward from the side portion in a substantially horizontal direction.

3. The article of footwear of claim 2 , wherein the sole further comprises a forefoot region and wherein the forefoot region of the sole includes a second elastomeric pad.

4. The article of footwear of claim 3 , wherein the second elastomeric pad is disposed under a big toe region of the article of footwear.

5. The article of footwear of claim 1 , wherein the second material is a polymer overlay over the first material.

6. The article of footwear of claim 1 , wherein the second portion is disposed directly adjacent to at least a portion of the sole on both the medial side and the lateral side.

7. The article of footwear of claim 3 , wherein the second elastomeric pad comprises a second aperture located in the central region for allowing moisture generated within the article of footwear to escape through the textile layer.

8. The article of footwear of claim 2 , wherein the lower portion of the sole is substantially smooth relative to the side portion of the sole.

9. An article of footwear comprising:
a sole comprising a textile layer and a plurality of elastomeric pads;
an upper comprising a first material and a second material,
wherein the upper is attached to the sole;
wherein the second material is disposed at a periphery of the upper and wherein the second material is tacky relative to the first material;
wherein at least one of the plurality of elastomeric pads comprises two or more substantially concentric ridges that encircle a central region;
wherein a geometry of each ridge includes a downwardly oriented surface and an upwardly oriented surface that meet at a peak portion of the ridge; and
wherein at least one of the plurality of elastomeric pads comprises an aperture located in the central region for allowing moisture generated within the article of footwear to escape through the textile layer, wherein a portion of the textile layer is exposed through the aperture.

10. The article of footwear of claim 9 , wherein the sole comprises a heel region and a toe region, and wherein the plurality of elastomeric pads includes an elastomeric pad in the heel region of the sole and an elastomeric pad in the toe region of the sole.

11. The article of footwear of claim 10 , wherein the elastomeric pad in the heel region comprises a heel aperture and the elastomeric pad in the toe region comprises a toe aperture.

12. The article of footwear of claim 11 , wherein the sole comprises a forefoot region, and wherein the forefoot region further comprises at least one elastomeric pad with ridges angled downwards in the forefoot region of the sole, and wherein a geometry of each of the ridges is configured to provide unidirectional traction to the article of footwear.

13. The article of footwear of claim 9 , wherein the upper comprises an ankle opening and an eyestay region extending down from the ankle opening towards a lateral side of the upper, and wherein one or more reinforcing strips extend between the eyestay region and a lower periphery of the upper, wherein each reinforcing strip is configured to resist stretching in a longitudinal direction, wherein the longitudinal direction extends lengthwise between a heel region and a forefoot region of the wrestling shoe.

14. The article of footwear of claim 9 , wherein the textile layer comprises spacer mesh material.

15. A wrestling shoe comprising:
an upper comprised of a first material and a second material, the second material being tacky compared to the first material;
a sole comprised of a textile strobel and a plurality of pads, the plurality of pads including a toe pad in a toe region of the sole and a heel pad in a heel region of the sole;
wherein the toe pad comprises a plurality of substantially concentric ridges that encircle a central region;
wherein the toe region includes a lower portion and a side portion, wherein the lower portion is substantially perpendicular relative to the side portion, wherein the lower portion and the side portion are substantially continuous;
wherein the toe pad comprises a toe pad aperture located in the central region for allowing moisture generated within the article of footwear to escape through the textile layer;
wherein a coefficient of friction of the second material is at least ten times greater than a coefficient of friction of the first material;
wherein the upper also comprises an eyestay region biased towards the lateral side of the upper; and
wherein the toe pad comprises a first plurality of downwardly-angled ridges, and wherein the heel pad comprises a second plurality of downwardly-angled ridges, wherein the first plurality of downwardly-angled ridges are associated with the side portion of the big toe region.

16. The wrestling shoe of claim 15 , wherein the heel pad comprises a heel pad aperture.

17. The wrestling shoe of claim 16 , further comprising an ankle str
