Non-slip tread with alveolar structure

Abstract

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.

1 . Non-slip tread characterized in that it comprises:
 an alveolar structure with cells of any shape comprising walls converging on a hole to form a funnel-shaped surface; and   holes passing right through the thickness of the tread and forming, in front view, a series that, in side view, corresponds to a transverse channel made inside the tread.   
     
     
         2 . Non-slip tread according to  claim 1  characterized in that the funnel-shaped surfaces made up of the walls of the cells of the alveolar structure that converge on the holes, during compression on the paving, get squashed to the ground so widening their size on the ground. 
     
     
         3 . Non-slip tread according to  claim 2 , characterized in that the compression on the paving of the funnel-shaped surface made up of the walls of the cells of the alveolar structure pushes the water into the hole to then make it flow into the transverse channel made inside the tread and flow outward sideways.
