Title: FOOTWEAR SOLE AND FOOTWEAR
Abstract:
Sole (1) for footwear, (10) comprising a support surface (2) extending between a heel portion (1") and a front sole portion (1') across a transition portion (4). The heel portion (1") delimits a plurality of entrance grooves (6, 6'), incident to the main direction of extension (X), which at an outer longitudinal rim (8) of the sole (1) have a reduced pitch compared to the corresponding pitch towards or at an inner longitudinal rim (12). The front sole portion (1') delimits at least one spiral-shaped groove (14), while the transition portion (4) comprises at least one oblique rotational element (16) which, towards the front sole portion (1'), is directed at the inner longitudinal rim (1.2) to facilitate the twisting deformation of the sole (1). The present invention further relates to footwear using such sole.
