Abstract

The present invention relates to a heel or wedge comprising two materials of different densities or hardnesses and its cover, top piece or tread (3) with a groove or grooves, this heel or wedge is to be applied to soles of classic, casual, sportive or other type of footwear. The heel or wedge construction presented by the described invention will enable the damping or softening of the initial impact of the heel or wedge to the ground without any loss of stability and proper support of the foot. The above mentioned heel or wedge is made from the assembly of two different density or hardness materials, being the lowest density material (2) applied to the rear area of the heel or wedge in conjunction to another higher density material (1) applied to the front part of said heel or wedge, the described assembled materials will then be applied on top of a cover, top piece or tread (3) that has at least one groove (4) across its entire bottom surface from side to side.
