Abstract
Components for articles of footwear and athletic equipment are provided including a high energy return foam having improved abrasion resistance. A variety of foams and foam components and compositions for forming the foams are provided. In some aspects, the foams and components including the foams can have exceptionally high energy return while also having improved durability and softness and an improved abrasion resistance. In particular, midsoles including the foams are provided for use in an article of footwear. Methods of making the compositions and foams are provided, as well as methods of making an article of footwear including one of the foam components. In some aspects, the foams and foam components can be made by injection molding or injection molding followed by compression molding.
