1. Midsole for sport shoes, especially for medium and long distance running, of soft elastic material, which has a recess formed on an underside thereof, and a stabilizing element of a material that is harder than the material forming the midsole inserted into said recess;
- wherein said stabilizing element has a U-shaped part filling said recess in the entirety of a heel edge area, a bar part which extends across the midsole in an area corresponding to a middle part of a wearer'"'"'s foot in a manner forming a window in which an island of the softly elastic midsole material engages, and a strip part which extends along the lateral side of the midsole up to at least approximately a little toe area;
wherein the bar part has a thickness which is about 20 to 70 percent of the thickness of the stabilizing element at a medial portion of the heel edge area.

Abstract
A midsole for athletic shoes, especially for medium and long distance track events, of soft elastic material, which in the heel area has, on its underside, a recess into which is inserted a stabilizing element of a material that is harder than that of the midsole is improved so that harmful supination positions are avoided. This is achieved by the fact that the stabilizing element (9) consists of a U-shaped part (10), covering the entire heel edge area, and a part which closes the U-shaped part at the middle part of the foot in a manner creating a window (13) into which an island of the full thickness of the midsole engages. The stabilizing element (9) also has a strip which extends along the lateral side of the midsole up to at least, approximately, the little toe area of a shoe provided with such a midsole.
