Abstract

A golf shoe includes a sole member integrally formed with a molding material, a structural member, and a plurality of receptacles in the bottom of the sole member. The structural member extends along at least a portion of the length of the sole member and is configured to not vertically overlap with any of the receptacles. A method of manufacturing a shoe with a sole member that has a structural member formed integrally therewith is also provided.

Claims

1. A golf shoe comprising:

a sole member having a length and which is integrally formed with a molding material, an integrated structural member formed within the molding material and which is completely covered by the molding material other than openings at the locations of a plurality of receptacles in the bottom of the sole member, each receptacle being configured to receive a cleat member,

wherein the structural member extends substantially the length of the sole member and is configured to not vertically overlap with any of the receptacles, and wherein the structural member comprises carbon fiber or a thermoplastic polyamide elastomer.

2. The golf shoe of claim 1, wherein the structural member comprises a plurality of openings that extend therethrough, each opening being aligned with at least one receptacle.

3. The golf shoe of claim 1, wherein the structural member comprises a plurality of cut-away portions, each cut-away portions being adjacent to, but not covering, at least one receptacle.

4. The golf shoe of claim 1, wherein the structural member comprises one or more grooved portions that extend longitudinally along at least a portion of the length of the shoe, the one or more grooved portions causing the structural member to have a 3-dimensional cross-sectional profile along its width at the areas of the one or more grooved portions.

5. The golf shoe of claim 4, wherein the golf shoe comprises at least two grooved portions that extend longitudinally along at least a portion of the length of the shoe.

6. The golf shoe of claim 1, wherein the structural member curves upwards at its lateral and medial edges.

7. The golf shoe of claim 1, wherein the structural member comprises at least one upwardly extending member, the upwardly extending member extending above an insole of the shoe to at least partially surround a foot of a person wearing the shoe.

8. The golf shoe of claim 1, wherein the structural member extends less than 75% of the length of the sole member.

9. The golf shoe of claim 1, further comprising an upper secured to a top portion of the sole member.

10. The golf shoe of claim 1, wherein at least a portion of the structural member is exposed at the bottom of the sole member.

11. The golf shoe of claim 1, wherein the structural member comprises a bridging portion that extends between a heel portion and a forefoot portion.

12. The golf shoe of claim 1, wherein the structural member varies in thickness along its length.

13. The golf shoe of claim 1, wherein the structural member is substantially constant in thickness along its length.

14. The golf shoe of claim 1, wherein the structural member bends or curves along at least a portion of its length.

15. The golf shoe of claim 1, wherein the molding material is a thermoplastic polyurethane.

16. A sole member having a length formed and for use with a golf shoe comprising:

an integrated structural member which is completely covered by a molding material, the structural member extending along at least a portion of the length of the sole member and providing rigidity to the sole member; and

the molding material completely surrounding the structural member, the molding material forming a heel portion and a forefoot portion of the sole member,

wherein the structural member extends substantially the length of the sole member and between the heel and forefoot portions to couple the heel and forefoot portions together, and wherein the structural member comprises carbon fiber or a thermoplastic polyamide elastomer.

17. The sole member of claim 16, further comprising:

a plurality of receptacles positioned on a bottom of the sole member, each receptacle being configured for receiving a cleat member,

wherein the structural member comprises a plurality of openings that extend therethrough, each opening being vertically aligned with at least one receptacle.

18. The sole member of claim 16, wherein the structural member comprises a plurality of cut-away portions, each cut-away portions being adjacent to, but not vertically overlapping, at least one receptacle.

19. The sole member of claim 16, wherein the structural member comprises one or more grooved portions that extend longitudinally along at least a portion of the length of the shoe, the one or more grooved portions causing the structural member to have a 3-dimensional cross-sectional profile along its width at the areas of the one or more grooved portions.

20. The sole member of claim 16, wherein the structural member curves upwards at its lateral and medial edges.

21. The sole member of claim 16, wherein the structural member comprises at least one upwardly extending member, the upwardly extending member extending above an upper surface of the molding material.

22. The sole member of claim 16, wherein the structural member extends less than 75% of the length of the sole member.

23. The sole member of claim 16, wherein at least a portion of the structural member is exposed at the bottom of the sole member.

24. The sole member of claim 16, wherein the structural member varies in thickness along its length.

25. The sole member of claim 16, wherein the structural member is substantially constant in thickness along its length.

26. The sole member of claim 16, wherein the structural member bends or curves along at least a portion of its length.

27. The sole member of claim 16, wherein the molding material is a thermoplastic polyurethane.
