METHOD FOR PRODUCING A SOLE OR A SOLE PART OF A SHOE

摘要

The invention relates to a method or producing a sole (1) or a sole part of a shoe (2), in particular of a sports shoe. To obtain a lightweight shoe which has good rebound characteristics, the invention provides the following steps: a) Producing plastic elements (3), the extent (a, b, c) of which in the three spatial direction lies between 2 mm and 15 mm, preferably between 3 mm and 9 mm, wherein the plastic elements (3) consist of a foamed thermoplastic elastomer based on urethane (TPU, E-TPU, TPE-U) and/or based on polyether block amide (PEBA); b) Introducing the plastic elements (3) into a moulding tool which has a cavity which corresponds to the shape of the sole (1) or the sole part to be produced; c) Connecting the plastic elements (3) located in the moulding tool to one another, wherein a binder is put into the moulding tool to make the connection and/or wherein heat is allowed to act on the plastic elements (3) to make the connection.
