The disclosure relates to articles of footwear and components thereof, including outsoles, which can be used in conditions normally conducive to the accumulation of soil on the outsoles. In particular, the disclosure relates to articles of footwear and components thereof including an outsole with a ground-facing crosslinked polymeric material having a wet-state glass transition temperature more than 6° C. less than its dry-state glass transition temperature. The outsoles can prevent or reduce the accumulation of soil on the footwear during wear on unpaved surfaces such as sporting fields. When the outsoles are wetted with water, the outsoles can become more compliant and/or can rapidly uptake and/or expel water, which can prevent soil from adhering to the outsole and/or can assist in shedding soil present on the outsole.

1. An outsole for an article of footwear, the outsole comprising: an outsole substrate having a ground facing surface; a crosslinked polymeric material on the ground facing surface and defining an external surface of the outsole, wherein the crosslinked polymeric material has a wet-state glass transition temperature and a dry-state glass transition temperature, each as characterized by a Glass Transition Temperature Test with a Neat Film Sampling Procedure, and wherein the wet-state glass transition temperature is at least 6 degrees C. less than the dry-state glass transition temperature; and a plurality of traction elements on the ground facing surface of the outsole substrate. 2. The outsole of claim 1, wherein the wet-state glass transition temperature of the crosslinked polymeric material is at least 15 degrees C. less than the dry-state glass transition temperature of the crosslinked polymeric material. 3. The outsole of claim 1, wherein the wet-state glass transition temperature of the crosslinked polymeric material ranges from at least 6 degrees C. to 40 degrees C. less than the dry-state glass transition temperature of the crosslinked polymeric material. 4. The outsole of claim 1, wherein the dry-state glass transition temperature of the crosslinked polymeric material ranges from −40 degrees C. to −80 degrees C. 5. The outsole of claim 1, wherein the crosslinked polymeric material is a physically crosslinked polymer network. 6. The outsole of claim 1, wherein the crosslinked polymeric material includes carbamate linkages. 7. The outsole of claim 1, wherein the crosslinked polymeric material comprises crystalline regions and amorphous hydrophilic regions, and wherein the crystalline regions are covalently bonded to the amorphous hydrophilic regions. 8. The outsole of claim 7, wherein the amorphous hydrophilic regions are present in the crosslinked polymeric material at a ratio ranging from 20:1 to 110:1 by weight relative to the crystalline regions. 9. The outsole of claim 1, wherein each of the plurality of traction elements comprises a terminal edge, and wherein the crosslinked polymeric material is not present on the terminal edges of any of the plurality of traction elements. 10. The outsole of claim 1, wherein one or more of the traction elements is selected from the group consisting of: a cleat, a stud, a spike, and a lug. 11. The outsole of claim 1, wherein the traction elements are integrally formed with the outsole substrate. 12. The outsole of claim 1, wherein the traction elements are removable traction elements. 13. An article of footwear comprising: an outsole having a first side and a ground-facing side opposite of the first side, a crosslinked polymeric material on the ground-facing side having a wet-state glass transition temperature and a dry-state glass transition temperature, each as characterized by a Glass Transition Temperature Test with a Neat Material Sampling Procedure, and wherein the wet-state glass transition temperature of the crosslinked polymeric material ranges from at least 6 degrees C. to 50 degrees C. less than the dry-state glass transition temperature of the crosslinked polymeric material, and a plurality of traction elements on the ground facing side of the outsole; andan upper operably secured to at least a portion of the first side of the outsole. 14. The article of claim 13, wherein the wet-state glass transition temperature of the crosslinked polymeric material ranges from 10 degrees C. to 30 degrees C. less than the dry-state glass transition temperature of the crosslinked polymeric material. 15. The article of claim 13, wherein the wet-state glass transition temperature of the crosslinked polymeric material ranges from 30 degrees C. to 45 degrees C. less than the dry-state glass transition temperature of the crosslinked polymeric material. 16. The article of claim 13, wherein the dry-state glass transition temperature of the crosslinked polymeric material ranges from −40 degrees C. to −80 degrees C. 17. The article of claim 13, wherein the crosslinked polymeric material comprises a physically crosslinked polymeric network comprising one or more polyurethane chains. 18. The article of claim 13, wherein the crosslinked polymeric material is in the form of a film having a dry-state film thickness ranging from 0.1 millimeters to 2 millimeters. 19. The article of footwear of claim 13, wherein the crosslinked polymeric material is a physically crosslinked polymer network. 20. The article of footwear of claim 13, wherein the crosslinked polymeric material includes carbamate linkages. 21. The article of footwear of claim 13, wherein the crosslinked polymeric material comprises crystalline regions and amorphous hydrophilic regions, and wherein the crystalline regions are covalently bonded to the amorphous hydrophilic regions. 22. The article of footwear of claim 21, wherein the amorphous hydrophilic regions are present in the crosslinked polymeric material at a ratio ranging from 20:1 to 110:1 by weight relative to the crystalline regions. 23. The article of footwear of claim 13, wherein each of the plurality of traction elements comprises a terminal edge, and wherein the crosslinked polymeric material is not present on the terminal edges of any of the plurality of traction elements. 24. The article of footwear of claim 13, wherein one or more of the traction elements is selected from the group consisting of: a cleat, a stud, a spike, and a lug. 25. The article of footwear of claim 13, wherein the traction elements are integrally formed with the outsole. 26. The article of footwear of claim 13, wherein the traction elements are removable traction elements.
