A non-slip tread, applicable to the footwear sector, having in correspondence of the heel and the front half-sole, two areas with alveolar structure whose cells consist of walls converging on a hole to form a funnel-shaped surface. Each hole is a through hole, that is, it passes right through the thickness of the tread and communicates with a transverse channel for lateral outflow made inside the tread. |
