ABSTRACT:
The invention relates to an outsole for sports shoes, particularly for shoes used for long-distance running on hard tracks. The outsole consists of a soft elastically flexible material, preferably plastics material, and is thickened rearwardly in wedge formation. In the region of the heel tread surface of the outsole, there is provided a recess which is open towards both side edges of the sole and in which a resilient elongate supporting member is fittingly insertable. Preferably a plurality of supporting members are inserted in corresponding recesses adjacent one another. The supporting members are replaceable and permit the effective sole flexibility in the region of the heel tread surface to be adapted to the individual requirements of the runner and the track.
