Abstract

An article of footwear includes a sole assembly, an upper secured to the sole assembly, a heel counter secured to the upper, and a heel pad removably attached to an inner surface of the heel counter.

Claims

1. An article of footwear comprising, in combination:

a sole assembly;

an upper secured to the sole assembly;

a heel counter secured to the upper; and

a heel pad removably attached to an inner surface of the heel counter.

2. The article of footwear of claim 1, wherein the heel pad includes at least one projection and the heel counter includes at least one recess, each recess receiving a corresponding projection.

3. The article of footwear of claim 2, wherein a peripheral edge of each projection is undercut so as to engage a corresponding recess in snap-fit fashion.

4. The article of footwear of claim 2, further comprising at least one fastener, each fastener configured to secure a projection within a corresponding recess.

5. The article of footwear of claim 4, wherein the fastener comprises a hook and loop fastener.

6. The article of footwear of claim 5, wherein a first portion of the hook and loop fastener is secured to the projection and a second portion of the hook and loop fastener is secured to the recess.

7. The article of footwear of claim 2, wherein each projection is of unitary construction with the heel pad.

8. The article of footwear of claim 1, wherein the heel pad includes at least one projection and the heel counter includes at least one aperture, each aperture receiving a corresponding projection.

9. The article of footwear of claim 8, wherein a peripheral edge of each projection is undercut so as to engage a corresponding aperture in snap-fit fashion.

10. The article of footwear of claim 8, wherein each projection is of unitary construction with the heel pad.

11. The article of footwear of claim 1, further comprising a collar secured to an interior surface of the heel counter, a lower edge of the collar positioned adjacent an upper edge of the heel pad.

12. The article of footwear of claim 11, wherein a rib is formed along an exterior surface of the collar proximate an upper edge of the collar, the rib extending along an upper edge of an upper of the sole assembly.

13. The article of footwear of claim 11, wherein the collar is formed of foam with a fabric lining.

14. The article of footwear of claim 1, wherein the heel counter includes a first recess on a medial side thereof and a second recess on a lateral side thereof, and the heel pad includes a first projection on a medial side thereof and a second projection on a lateral side thereof, the first recess receiving the first projection and the second recess receiving the second projection.

15. The article of footwear of claim 14, further comprising a first fastener securing the first projection within the first recess and a second fastener securing the second projection within the second recess.

16. The article of footwear of claim 1, wherein the heel counter is formed of plastic.

17. The article of footwear of claim 1, wherein the heel pad is formed of polyurethane.

18. The article of footwear of claim 1, wherein the heel pad is formed of EVA.

19. The article of footwear of claim 1, wherein the heel pad is formed of a plurality of layers laminated together.

20. The article of footwear of claim 1, further comprising a liner secured to an interior surface of the heel pad.

21. The article of footwear of claim 1, wherein one portion of the heel pad is formed of a first material and a second portion of the heel pad is formed of a second material.

22. The article of footwear of claim 21, wherein an outer portion of the heel pad has a hardness greater than a hardness of an inner portion of the heel pad.

23. The article of footwear of claim 1, wherein the heel pad has a varying thickness.

24. An article of footwear comprising, in combination:

a sole assembly;

an upper secured to the sole assembly;

a heel counter secured to the upper and having a plurality of recesses; and

a heel pad having a plurality of projections extending outwardly from an exterior surface thereof, each projection received by a corresponding recess to removably attach the heel pad to the heel counter.

25. The article of footwear of claim 24, further comprising at least one fastener, each fastener configured to secure a projection within a corresponding recess.

26. The article of footwear of claim 25, wherein the fastener comprises a hook and loop fastener, a first portion of the hook and loop fastener secured to the projection and a second portion of the hook and loop fastener secured to the recess.

27. The article of footwear of claim 24, further comprising a collar secured to an interior surface of the heel counter, a lower edge of the collar positioned adjacent an upper edge of the heel pad.

28. An article of footwear comprising, in combination:

a sole assembly comprising an outsole, a midsole and an insole;

an upper secured to the midsole;

a heel counter secured to the upper and having a first recess on a medial side thereof and a second recess on a lateral side thereof;

a heel pad having a first projection on a medial side thereof and a second projection on a lateral side thereof, the first recess receiving the first projection and the second recess receiving the second projection;

a first fastener securing the first projection within the first recess;

a second fastener securing the second projection within the second recess; and

a collar secured to an interior surface of the upper, a lower surface of the collar adjacent an upper edge of the heel pad.

29. The article of footwear of claim 28, wherein each fastener comprises a hook and loop fastener, a first portion of each hook and loop fastener secured to a projection and a second portion of each hook and loop fastener secured to a recess.

30. An article of footwear comprising, in combination:

a sole assembly comprising an outsole, a midsole and an insole;

an upper secured to the midsole;
