Abstract

Disclosed herein are articles of manufacture, methods of manufacturing articles, and methods of using articles of manufacture, having an open-cell foam material and a mesh component present on at least parts of an external surface of the article. The open-cell foam material and the mesh component can cooperate to effectively reduce soil accumulation on the external surface of the article when the external surface of the article comes into direct contact with wet soil.

Claims

1. An article of manufacture comprising:

a substrate body;

an open-cell foam material having a first side secured to the substrate body and an opposing second side;

a mesh component present on and/or adjacent to the second side of the open-cell foam material, wherein the mesh component covers a first portion of the open-cell foam material while leaving a second portion of the open-cell foam material uncovered, such that a first side of the mesh component covers the first portion and an opposing second side of the mesh component forms at least a part of an external surface of the article, and the second portion of the open-cell foam material forms at least another part of the external surface; and

a plurality of traction elements attached to the substrate body, wherein one or more of the plurality of traction elements is selected from the group consisting of;

a cleat, a stud, a spike, and a lug.

2. The article of claim 1, wherein the mesh component comprises a material selected from the group consisting of a metal, a polymer, and combinations thereof.

3. The article of claim 1, wherein the mesh component is formed from a plurality of elongated elements.

4. The article of claim 1, wherein at least a portion of the mesh component is embedded into the substrate body.

5. The article of claim 1, wherein the mesh component has a plurality of openings, and at least a portion of the plurality of openings each have a surface area of from about 1 to about 15 mm².

6. The article of claim 1, wherein the mesh component comprises a plurality of elongated elements in which at least a portion of the plurality of elongated elements each have a diameter of less than about 2 mm.

7. The article of claim 1, wherein the mesh component is at least partially affixed to the open-cell foam material.

8. The article of claim 1, wherein the open-cell foam material has an average cell diameter of from about 0.65 to about 1.4 mm as characterized by a Cell Diameter Test with a Sampling Procedure.

9. The article of claim 1, wherein the open-cell foam material has a thickness of from about 0.1 to about 2 mm.

10. The article of claim 1, wherein the open-cell foam material comprises an ethylene-alkyl acrylate copolymer component consisting of an ethylene-alkyl acrylate copolymer or a combination of two or more ethylene-alkyl acrylate copolymers.

11. The article of claim 10, wherein a concentration of the ethylene-alkyl acrylate copolymer component present in the open-cell foam material is from about 40 to about 80 parts per hundred by weight based on a total polymer content of the open-cell foam material.

12. The article of claim 1, wherein the open-cell foam material comprises an ethylene-alkyl acrylate copolymer component, wherein the ethylene-alkyl acrylate copolymer component of the open-cell foam material comprises a copolymer of ethylene and methyl acrylate, or a copolymer of ethylene and ethyl acrylate, or a combination of both.

13. The article of claim 1, wherein the article is an outsole for an article of footwear.

14. The article of claim 13, wherein the open-cell foam material is present on at least about 50% of a ground-facing surface of the outsole.

15. The article of claim 13, wherein the open-cell foam material forms a larger portion of a ground-facing surface of the outsole than the mesh component.

16. The article of claim 1 wherein the article is an outsole for an article of footwear and, wherein the traction elements are integrally formed with an outsole.

17. An article of manufacture comprising:

a substrate body;

an open-cell foam material having a first side secured to the substrate body and an opposing second side;

a mesh component present on and/or adjacent to the second side of the open-cell foam material, wherein the mesh component covers a first portion of the open-cell foam material while leaving a second portion of the open-cell foam material uncovered, such that a first side of the mesh component covers the first portion and an opposing second side of the mesh component forms at least a part of an external surface of the article, and the second portion of the open-cell foam material forms at least another part of the external surface; and

a plurality of traction elements attached to the substrate body, wherein each of the plurality of traction elements comprises a terminal edge, and wherein the open-cell foam material is not present on the terminal edges of any of the plurality of traction elements.

18. The article of claim 17, wherein the article is an outsole for an article of footwear.

19. An article of manufacture comprising:

a substrate body;

an open-cell foam material having a first side secured to the substrate body and an opposing second side;

a mesh component present on and/or adjacent to the second side of the open-cell foam material, wherein the mesh component covers a first portion of the open-cell foam material while leaving a second portion of the open-cell foam material uncovered, such that a first side of the mesh component covers the first portion and an opposing second side of the mesh component forms at least a part of an external surface of the article, and the second portion of the open-cell foam material forms at least another part of the external surface; and

a plurality of traction elements attached to the substrate body, wherein the traction elements are removable traction elements.

20. The article of claim 19, wherein the article is an outsole for an article of footwear.
