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.
