ABSTRACT:
A high-traction sole unit, including a rubber tread and a series of more or less rigid lattice inserts, which are separated among them by cavities and each of them is composed of undulated elements and a series of inverted T-shaped transverse ribs, the axes of which are perpendicular, at the points of relative intersection, to an S-shaped curved line extending from the heel to the toe of the sole unit; the lattice inserts are joined together by rubber or elastomeric elements, which are constituted by the same material that constitutes the tread or the wedge of the footwear. To usefully lighten the structure, further ribs of rubber are provided, differing from each other in shape and dimensions, which are suitably located within concavities in the inserts; finally the lattice inserts can be constructed of different materials, such as carbon fiber or fiber-filled plastic material or metal materials.
