Abstract

La présente invention concerne une semelle de chaussure (1), comprenant un élément en forme de bande longue (4) de l'avant à l'arrière entre des éléments de semelle d'usure internes (23, 33) et des éléments de semelle d'usure externes (24, 34). L'élément en forme de bande (4) comporte des saillies (40). Les saillies (40) s'étendent en continu ou par intermittence dans la direction X de l'avant vers l'arrière. Les surfaces de contact avec le sol des saillies (40) font saillie en dessous des surfaces de contact avec le sol des éléments de semelle d'usure internes (23, 33) et des éléments de semelle d'usure externes (24, 34). Soit l'une, soit les deux conditions (a) et (b) ci-dessous sont satisfaites. (a) La dureté de la semelle intercalaire (2) de l'élément en forme de bande (4) est plus grande que la dureté de la semelle intercalaire (2) des éléments de semelle d'usure internes (23, 33) et des éléments de semelle d'usure externes (24, 34). (b) La dureté de la semelle externe (3) de l'élément en forme de bande (4) est plus grande que la dureté de la semelle externe (3) des éléments de semelle d'usure internes (23, 33) et des éléments de semelle d'usure externes (24, 34).
