Article of footwear with soil-shedding performance
First Claim
1. An outsole for an article of footwear, the outsole comprising:
- an outsole backing member having a ground-facing side, wherein the ground-facing side of the outsole backing member includes a plurality of traction elements; and
a film secured to at least a portion of the ground-facing side of the outsole backing member and defining an external surface of the outsole, wherein the film comprises a crosslinked polymeric network, and wherein the film has a swell thickness increase at 1 hour greater than 20%, as characterize by a Swelling Capacity Test with a Footwear Sampling Procedure.

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 network film having a swell thickness increase at 1 hour greater than 20%. 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.
