A method for producing a molded part, in particular a component of a sporting good, includes providing a mixture of a polymer melt and a foaming agent and injecting the mixture into a mold. The method includes solidifying at least a first portion of the molded part without foaming and at least a second portion of the molded part after foaming inside the mold, wherein the mixture includes a polymer having an average molecular mass corresponding to a viscosity number ≥130 ml/g, preferably ≥170 ml/g, more preferably ≥190 ml/g and most preferably ≥225 ml/g, wherein the viscosity number is determined via solution viscometry according to the ISO 307 standard.
