Article of footwear with soil-shedding performance
First Claim
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.

Abstract
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.

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; and an upper operably secured to at least a portion of the first side of the outsole. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
