FOOTWEAR SOLE, MORE PARTICULARLY SPORTS FOOTWEAR SOLE, AND FOOTWEAR PROVIDED WITH SUCH A SOLE

摘要

A footwear sole, more particularly a sports footwear sole, is provided. The extension of the sole can be adjusted in a transverse direction. The sole comprises a deformable portion made of the same material as the rest of the sole and is made with no discontinuity with the rest of the sole. The deformable portion extends in the longitudinal direction of the sole over the whole length of the sole or at least over a substantial portion thereof. Owing to this solution, the sole does not have any discontinuity areas and the non-uniformities in the structural features of the sole, for instance in terms of flexional and torsional rigidity, are remarkably limited.
