Abstract: A process for producing a shoe sole, having a hybrid material of a polyurethane foam as a matrix material and an inlay component of expanded particles of a thermoplastic polyurethane is provided. The process includes preparing an inlay form by joining the expanded particles of a thermoplastic polyurethane in an amount and size of the desired inlay; preparing the shoe sole by placing the prepared inlay form in a shoe sole mold such that an edge of the inlay component is 0.2 cm or more from an edge of the shoe sole mold; embedding the inlay form within a reaction mixture in the shoe sole mold; and reacting the reaction mixture to form the matrix in the shoe sole mold.
