Inlay sole for shoes

An inlay sole for shoes, comprising:

• wherein each of the multiple sole parts of the upper layer is interlocked with at least one of the other multiple sole parts in a sinuously conjoining manner by having the multiple projections interlocked with corresponding matching recesses of each of the other multiple sole parts of the upper layer in order to form the assembled upper layer, and
• each of the multiple sole parts of the lower layer is interlocked with at least one of the other multiple sole parts in a sinuously conjoining manner by having the multiple projections interlocked with the corresponding matching recesses of each of the other multiple sole parts of the lower layer in order to form the assembled lower layer,
• the abutting edges of the multiple sole parts of the assembled upper layer form a single curved surface arranged orthogonally relative to upper and lower surfaces of the assembled upper layer,
• the abutting edges of the multiple sole parts of the assembled lower layer form a single curved surface arranged orthogonally relative to upper and lower surfaces of the assembled lower layer, and
• each of the abutting edges of the multiple sole parts of the assembled upper layer is offset with respect to each of the abutting edges of multiple sole parts of the assembled lower layer.

• the heel sole part has a U-shaped outer periphery, and a concave inner periphery,
• wherein the abutting edges of the multiple sole parts of the assembled upper layer form a single curved surface arranged orthogonally relative to upper and lower surfaces of the assembled upper layer,
• the abutting edges of the multiple sole parts of the assembled lower layer form a single curved surface arranged orthogonally relative to upper and lower surfaces of the assembled lower layer, and
• each of the abutting edges of the multiple sole parts of the assembled upper layer is offset with respect to each of the abutting edges of the multiple sole parts of the assembled lower layer, and
• wherein at least a first one of the sole parts in each of the layers has a first Shore hardness and an abutting edge which abuts against another of the abutting edges of a second one of the sole parts having a second Shore hardness, the second Shore hardness being higher than the first Shore hardness, and
• since each of the abutting edges of the assembled upper layer is offset with respect to each of the abutting edges of the assembled lower layer,
• a portion of the second sole part of the upper layer that is located directly above a portion of the first sole part of the lower layer forms a soft transition area of the inlay sole,
• the soft transition area having greater softness as compared to other areas of the inlay sole where another portion of the second sole art of the upper layer is located,
• wherein the second sole part is located at a central portion of the inlay sole.
