Abstract

An outsole component for use in an article of footwear is manufactured using a molding process that incorporates a second polymeric material with a film component including a first layer formed of a polymeric hydrogel material. The first layer forms the external or ground-facing layer of the outsole. Methods of manufacturing the outsole component, as well as articles of footwear including outsole component and methods of manufacturing such articles of footwear are also described.

First claim

What is claimed is:

1. An outsole component for an article of footwear, the outsole component comprising:
a ground-contacting surface;
at least one flat film component having a consistent thickness, the at least one flat film component having a first surface, a second surface opposed to the first surface, and an external perimeter, the at least one flat film component compositionally comprising a polymeric hydrogel material, the polymeric hydrogel material defining at least a portion of the first surface of the at least one flat film component and at least a portion of the ground-contacting surface of the outsole component;
a second polymeric material operably connected to the second surface of the at least one flat film component and to the entire external perimeter of each of the one or more flat film components; and
one or more traction elements;
wherein the at least one flat film component fits between or around the one or more traction elements.

2. The outsole component of claim 1 , wherein the one or more traction elements comprise a ground-contacting surface, and the ground-contacting surface of the one or more traction elements does not comprise the polymeric hydrogel material of the at least one flat film component.

3. The outsole component of claim 1 , wherein the at least one flat film component further comprises a backing layer operably connected to the first layer, the backing layer compositionally comprising a third polymeric material.

4. The outsole component of claim 1 , wherein the at least one flat film component further comprises: a layered film comprising a first layer of polymeric hydrogel material and a backing layer comprising a third polymeric material.

5. The outsole component of claim 1 , wherein the one or more traction elements are formed integrally with or operably coupled with a molded outsole component.

6. The outsole component of claim 1 , wherein the second polymeric material is a thermoplastic polymeric material.

7. The outsole component of claim 3 , wherein the third polymeric material is a thermoplastic polymeric material.

8. The outsole component of claim 7 , wherein the second polymeric material and the third polymeric material are of substantially the same composition.

9. The outsole component of claim 7 , wherein the second polymeric material and the third polymeric material are of substantially different compositions.

10. The outsole component of claim 1 , wherein the one or more traction elements are made of a fourth polymeric material.

11. The outsole component of claim 7 , wherein the second polymeric material and the second polymeric material are of substantially the same composition.

12. The outsole component of claim 10 , wherein the fourth polymeric material has a greater level of abrasion resistance than the second polymeric material.

13. The outsole component of claim 1 , wherein traction elements are lugs, cleats, studs, spikes, or a combination thereof.

14. The outsole component of claim 1 , wherein the polymeric hydrogel material is a thermoplastic hydrogel material.

15. The outsole component of claim 1 , wherein the polymeric hydrogel material comprises one or more polymers selected from a polyurethane, a polyamide homopolymer, a polyamide copolymer, and any combination thereof.

16. The outsole component of claim 15 , wherein the polymeric hydrogel material comprises a polyurethane.

17. The outsole component of claim 16 , wherein the polyurethane is a thermoplastic polyurethane.

18. The outsole component of claim 1 , wherein the polymeric hydrogel material comprises polymers or copolymers of polyurethane, polyurea, polyester, polycarbonate, polyetheramide, addition polymers of ethylenically unsaturated monomers, and any combination thereof.

19. An article of footwear comprising the outsole component according to claim 1 .
