The disclosure relates to methods of using articles of footwear and components thereof, including outsoles, in conditions normally conducive to the accumulation of soil on the outsoles. In particular, the disclosure relates to a method of using an article of footwear having an outsole that includes a film on its ground facing surface. 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. Thus, the methods provided herein can prevent or reduce the accumulation of soil on the footwear during wear on unpaved surfaces such as sporting fields.

1. A method of using an article of footwear, the method comprising: providing the article of footwear having an upper and an outsole operably secured to the upper, wherein the outsole has a ground side, and includes a film in a dry state forming the ground side, and wherein the film comprises a hydr
1. A method of using an article of footwear, the method comprising: providing the article of footwear having an upper and an outsole operably secured to the upper, wherein the outsole has a ground side, and includes a film in a dry state forming the ground side, and wherein the film comprises a hydrogel, wherein the outsole comprises a plurality of traction elements;exposing the film in the dry state to water to take up the water into the hydrogel of the film, wherein the taken up water swells the film;pressing the outsole with the swollen film onto a ground surface to compress the swollen film, wherein the compression of the swollen film expels a portion of the taken up water from the film into soil of the ground surface;lifting the outsole from the ground surface to release the compression from the film; andtaking up additional water into the hydrogel of the film after releasing the compression from the film, wherein the additional taken up water swells the film. 2. The method of claim 1, wherein the method further comprises pressing at least a portion of the traction elements into the ground surface prior to pressing the swollen film onto the ground surface. 3. The method of claim 1, wherein the film in the dry state has a first film thickness ranging from 0.1 millimeters to 1 millimeter. 4. The method of claim 3, wherein the swollen film has a second film thickness that is at least 150% of the first film thickness. 5. The method of claim 1, wherein the film in the dry state has a first storage modulus and the swollen film has a second storage modulus, and wherein the second storage modulus of the swollen film is less than the first storage modulus. 6. The method of claim 1, wherein the hydrogel comprises crystalline regions and amorphous hydrophilic regions, wherein the amorphous regions are covalently bonded to the crystalline regions. 7. The method of claim 6, wherein the amorphous hydrophilic regions are bonded to the crystalline regions with carbamate linkages. 8. The method of claim 6, wherein the amorphous hydrophilic regions are present in the hydrogel at a ratio of at least 20:1 by weight relative to the crystalline regions. 9. The method of claim 1, wherein then hydrogel comprises a crosslinked polymeric network. 10. The method of claim 9, wherein the crosslinked polymeric network is a physically crosslinked polymeric network. 11. The method of claim 9, wherein the crosslinked polymeric network has one or more carbamate linkages. 12. The method 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. 13. The method of claim 1, wherein the traction elements are integrally formed with the outsole. 14. The method of claim 1, wherein the traction elements are removable traction elements. 15. A method of using an article of footwear, the method comprising: providing the article of footwear having an upper and an outsole operably secured to the upper, wherein the outsole has a ground side, and includes a film in a dry state forming the ground side, and wherein the film comprises a crosslinked polymeric network, wherein the outsole comprises a plurality of traction elements;exposing the film in the dry state to water to swell the film with the water;pressing the outsole onto a surface to compress the swollen film, wherein the compression of the swollen film expels a portion of the taken up water from the film; andlifting the outsole from the surface to release the compression from the film; re-swelling the film with additional water after releasing the compression from the film. 16. The method of claim 15, wherein the film in the dry state has a first film thickness ranging from 0.1 millimeters to 1 millimeter. 17. The method of claim 16, wherein the swollen film has a second film thickness that is at least 150% of the first film thickness. 18. The method of claim 15, wherein the steps of pressing the outsole onto the surface and lifting the outsole from the surface are performed in a foot strike motion. 19. The method of claim 18, wherein the step of exposing the film in the dry state to the water is performed in the foot strike motion. 20. The method of claim 15, wherein the crosslinked polymeric network comprises crystalline regions and amorphous hydrophilic regions, wherein the amorphous regions are covalently bonded to the crystalline regions. 21. The method of claim 20, wherein the amorphous hydrophilic regions are bonded to the crystalline regions with carbamate linkages. 22. The method of claim 20, wherein the amorphous hydrophilic regions are present in the hydrogel at a ratio of at least 20:1 by weight relative to the crystalline regions. 23. The method of claim 15, wherein the crosslinked polymeric network is a physically crosslinked polymeric network. 24. The method of claim 15, wherein the crosslinked polymeric network has one or more carbamate linkages. 25. The method of claim 15, wherein one or more of the traction elements is selected from the group consisting of: a cleat, a stud, a spike, and a lug. 26. The method of claim 15, wherein the traction elements are integrally formed with the outsole. 27. The method of claim 15, wherein the traction elements are removable traction elements. 28. A method of using an article of footwear, the method comprising: providing the article of footwear having an upper and an outsole operably secured to the upper, wherein the outsole has a ground side, and includes a hydrogel in a dry state forming the ground side, wherein the outsole comprises a plurality of traction elements;exposing the hydrogel in the dry state to water to take up the water into the hydrogel to provide a wetted hydrogel on the ground side of the outsole;pressing the outsole with the wetted hydrogel onto a ground surface to compress the wetted hydrogel, wherein the compression of the wetted hydrogel expels a portion of the taken up water from the wetted hydrogel into soil of the ground surface;lifting the outsole from the ground surface to release the compression from the hydrogel; andtaking up additional water into the hydrogel of the film after releasing the compression from the hydrogel. 29. The method of claim 28, wherein the hydrogel in the dry state has a first thickness on the ground side of the outsole ranging from 0.1 millimeters to 1 millimeter. 30. The method of claim 29, wherein the wetted hydrogel has a second thickness that is at least 150% of the first thickness. 31. The method of claim 28, wherein the method further comprises pressing at least a portion of the traction elements into the ground surface prior to pressing the wetted hydrogel onto the ground surface. 32. The method of claim 28, wherein the hydrogel comprises crystalline regions and amorphous hydrophilic regions, wherein the amorphous regions are covalently bonded to the crystalline regions. 33. The method of claim 32, wherein the amorphous hydrophilic regions are bonded to the crystalline regions with carbamate linkages. 34. The method of claim 32, wherein the amorphous hydrophilic regions are present in the hydrogel at a ratio of at least 20:1 by weight relative to the crystalline regions. 35. The method of claim 28, wherein then hydrogel comprises a crosslinked polymeric network. 36. The method of claim 35, wherein the crosslinked polymeric network is a physically crosslinked polymeric network. 37. The method of claim 35, wherein the crosslinked polymeric network has one or more carbamate linkages. 38.
