Abstract: An inlay sole for shoes is made up of sole pieces of varying Shore hardness which engage with each other on abutting edges, the width of which corresponds to the thickness of the sole pieces, with matching sinuous projections and matching recesses. The projections form extensions which engage in backcuts in the recesses, the inlay sole being made of several layers of sole pieces assembled as above. The abutting edges are offset with relation to each other from layer to layer.

Abstract: The invention relates to an inlay sole for shoes, consisting of sole parts of different Shore hardness, wherein, at abutting edges, the width of which abutting edges corresponds to the thickness of the sole parts, said sole parts are interlocked with each other in sinuously conjoining manner by means of projections and matching recesses, such that the projections form extensions that engage undercuts in the recesses, the inlay sole consisting of a plurality of layers of thus assembled sole parts. The respective abutting edges are offset with respect to each other from layer to layer.
