Abstract

An article of footwear includes a sole, an upper defining a foot cavity, and a brace member. The brace member is comprised of a non-elastic resilient material. The brace member is positioned within a pocket in the upper and extends from a heel portion to above an ankle portion of the upper. The brace member may be provided with a top plate member and a base plate member with a central shaft extending between the top plate member and the base plate member. The central shaft may have a C-shape that curves around an ankle of a human foot positioned within the foot cavity.

First claim

What is claimed is:

1. An article of footwear comprising: a sole defining a rearward heel section and a forward toe section of the article of footwear; an upper coupled to the sole, the upper defining a foot cavity, and a brace system comprising: a first brace member including an inflection point located at an intermediate location along a length of the brace member, wherein the first brace is configured to bend to a greater degree in a forward direction about the inflection point than at other locations along the length of the brace member, and a second brace member including an inflection point located at an intermediate location along a length of the second brace member, wherein the second brace is configured to bend in a forward direction about the inflection point, wherein the first brace member is configured to bend independently of the second brace member, and wherein each brace is positioned within the heel section and is configured to bend toward the toe section of the article of footwear.

2. The article of footwear of claim 1 , wherein:
the sole defines a medial side and a lateral side;
the first resilient brace member is disposed on the medial sole side within the heel section; and
the second resilient brace member is disposed on the lateral sole side within the heel section.

3. The article of footwear of claim 1 , wherein each brace member possesses a curvature including the inflection point operable to permit forward flexure of the brace member.

4. The article of footwear of claim 1 , wherein:
the sole possesses a longitudinal dimension and a transverse dimension;
the brace member moves along the longitudinal dimension of the sole as the brace member moves forward; and
the brace member resists movement along the sole transverse dimension.

5. The article of footwear of claim 1 , wherein a portion of each brace is positioned within the sole.

6. The article of footwear of claim 1 , wherein each brace member is formed of a resilient polymer.

7. The article of footwear of claim 1 , wherein each brace member forms a single integral component.

8. The article of footwear of claim 7 , wherein each brace member is formed of a resilient polymer.

9. The article of footwear of claim 1 , wherein each brace member bends about the inflection point from a normal position to a flexed position upon the application of force, and resiliently returning to the normal position once the applied force is removed.

10. The article of footwear of claim 1 , wherein each brace member is configured to deform from an original shape upon application of force and return to the original shape when the applied force is removed.

11. An article of footwear comprising: a shoe sole defining a rearward heel section and a forward toe section of the article of footwear; an upper coupled to the sole, the upper defining a foot cavity configured to receive a foot; and a brace system including: a first brace member extending distally from the sole and into the upper, and a second brace member extending distally from the sole and into the upper, wherein, in the distal direction, each brace member extends rearward from the sole to an inflection point, and then extends forward from the inflection point such that each brace member extends from a position below an ankle of the wearer, travels around a dorsal side of the ankle, and extends upward above the ankle, wherein each brace member comprises a resilient polymer material, wherein each brace member is more flexible at the inflection point than at other locations on the brace member, and wherein each brace is positioned within the heel section and is configured to bend toward the toe section of the article of footwear.

12. The article of footwear of claim 11 , wherein:
the sole defines a medial side and a lateral side;
the first brace member is disposed on the medial side; and
the second brace member is disposed on the lateral side.

13. The article of footwear of claim 12 , wherein the brace members are oriented on the sole such that the first brace member is positioned directly across from the second brace member.

14. The article of footwear of claim 11 , wherein each brace member comprises:
a top portion,
a bottom portion, and
a shaft portion oriented between the top portion and the bottom portion.

15. The article of footwear of claim 11 , wherein a portion of each brace member is disposed within the sole.

16. The article of footwear of claim 11 wherein each brace member is resilient, bending about the inflection point from a normal position to a flexed position upon the application of force, and resiliently returning to the normal position once the applied force is removed.

17. The article of footwear of claim 11 , wherein each brace member is resilient, deforming from an original shape upon application of force and returning to the original shape when the applied force is removed.

18. The article of footwear of claim 11 , wherein the article of footwear is an athletic shoe with a cleated sole.

19. The article of footwear of claim 11 , wherein the first brace member operates independently of the second brace member.

20. The article of footwear of claim 11 , wherein the first brace member is configured to bend independently of the second brace member.

21. The article of footwear of claim 11 , wherein each brace member forms a single integral component.

22. An article of footwear comprising: a sole defining a rearward heel section and a forward toe section of the article of footwear, wherein the sole further defines a medial side and a lateral side of the article of footwear; an upper coupled to the sole, the upper defining a foot cavity configured to receive a foot; and a brace system including: a first brace member disposed on the lateral side of the sole, the first brace member extending distally from the sole and into the upper, wherein the first brace member comprises a top portion, a bottom portion, and an arcuate shaft portion oriented between the top portion and the bottom portion, the arcuate shaft portion including an inflection point configured to permit a greater degree of flexure at the arcuate shaft portion than the top portion and the bottom portion of the first brace member, and a second brace member disposed on the medial side of the sole, the second brace member extending distally from the sole and into the upper, wherein the second brace member comprises a top portion, a bottom portion, and an arcuate shaft portion oriented between the top portion and the bottom portion, the arcuate shaft portion including an inflection point configured to permit a greater degree of flexure at the arcuate shaft portion than the top portion and the bottom portion of the second brace member, wherein each brace member forms a single integral component comprising polymer material, wherein each brace member is resilient, deforming from an original shape upon application of force an returning to the original shape when the applied force is removed, and wherein each brace is positioned within the heel section and configured to bend toward the toe section of the article of footwear.

23. The article of footwear of claim 22 , wherein the brace members are oriented on the sole such that the first brace member is positioned directly across from the second brace member.

24. The article of footwear of claim 23 , wherein the first brace member is configured to bend independently of the second brace member.
