Abstract: Shoe sole comprising a main structure that defines a tread surface and opposing sides of the sole, said main structure comprising a top layer facing, in use, the sole of the foot, a bottom layer facing the ground, and a reinforcing member interposed between said top and bottom layers. The reinforcing member is made of a material with greater rigidity than the bottom layer, and comprises a front portion and a rear portion joined together by a bridging section. A forefoot through opening is defined on the front portion and a hindfoot through opening is defined on the rear portion, in such a way that a midfoot through opening is defined between the bridging section and the bottom layer.

Abstract: Shoe sole (100) comprising a main structure (10) that defines a tread surface (1) and opposing sides (11, 12) of the sole, said main structure (10) comprising a top layer (16) facing, in use, the sole of the foot, a bottom layer (15) facing the ground, and a reinforcing member (5) interposed between said top (16) and bottom layers (15). The reinforcing member (5) is made of a material with greater rigidity than the bottom layer (15), and comprises a front portion (52) and a rear portion (54) joined together by a bridging section (53). A forefoot through opening (20) is defined on the front portion and a hindfoot through opening (40) is defined on the rear portion, in such a way that a midfoot through opening (30) is defined between the bridging section (53) and the bottom layer (15).
