ABSTRACT:
In a shoe (1), especially a sport shoe or shoe for medical purposes, with an outsole and a midsole attached to an upper between the outsole and the upper as well as with means for adjusting the height and/or hardness/damping characteristics of the sole, at least in the heel area, via damping inserts that are able to be used interchangeably. This is achieved by the fact that outsole (2) is designed to be separable from the midsole, at least in a portion of the sole extending from the arch area (7) rearward to the heel, and then reattached. A single-part or multiple-part damping insert (14), made of flexible material, can be interchangeably inserted into a space (13) formed between the midsole and the outsole when the outsole (2) is separated.
