  • Patent number: 10092062
    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 contact angle less than 80°. 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.

    Abstract: An apparatus is disclosed for flatproofing a tire and wheel assembly with a flexible, lightweight foam-fill by supplying at least two polyurethane reactive materials to a static mixer. The static mixer mixes the reactants, and a nucleating gas is supplied to the mixed reactants in the static mixer to form a liquid reactant mixture with entrained gas. The reactant mixture is injected into the tire and wheel assembly where the mixture reacts and foams replacing the air in the tire with a flexible, lightweight semi-open cell foam-fill. The foam-filled tire and wheel assembly is then allowed to cure.
