Article of footwear with soil-shedding performance
First Claim
1. An outsole for an article of footwear, the outsole comprising:
- an outsole substrate comprising a ground-facing side and an opposing second side configured to be secured to an upper for an article of footwear, one or more traction elements operably secured to the ground-facing side of the outsole substrate, a dispersion present on at least a portion of the ground facing side of the outsole substrate, and a water-permeable membrane, wherein the water-permeable membrane is present on at least a portion of the ground-facing side of the outsole substrate, wherein the dispersion comprises a polymeric continuous phase and a hydrophilic dispersant, and the dispersion has a water uptake capacity at 24 hours greater than 40% by weight, as characterized by the Water Uptake Capacity Test with the 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 having a dispersion present on a ground facing surface of the outsole. The dispersion compositionally includes a polymeric continuous phase and a hydrophilic dispersant, and exhibits a water uptake capacity at 24 hours greater than 40% by weight. 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.
