Shoe sole and a shoe fitted with such a sole

Abstract

The present invention provides a shoe sole including a main shock-absorber part that extends in the hindfoot region and from the medial side towards the lateral side of said sole, said main shock-absorber part comprising top and bottom elements and a partition element having at least one portion with a longitudinal axis (P), said partition element extending between said top and bottom elements so as to form at least two cavities, namely a medial cavity and a lateral cavity that open out respectively to the medial side and to the lateral side of said sole. Advantageously, the hind edges of the top and bottom elements include respective medial and lateral top regions and medial and lateral bottom regions arranged on either side of said axis (P), and the medial and lateral top regions extend in rectilinear manner respectively towards the lateral and medial bottom regions, so as to form an X-shaped structure with a longitudinal axis (l) that coincides with said axis (P).

Description

TECHNICAL FIELD[0001]The present disclosure relates to the technical field of shoe soles, in particular for sporting activities, and to shoes fitted with such soles, in particular shoe soles including a main shock-absorber part that extends in the hindfoot region and from the medial (inner) side towards the lateral (outer) side of said soles, the main shock-absorber part comprising top and bottom elements and a partition element that extends between said top and bottom elements so as to form at least two cavities, namely a medial cavity and a lateral cavity, that open out respectively to the medial side and to the lateral side of said soles.BACKGROUND[0002]Shoe soles, in particular for sporting activities, need to satisfy numerous requirements. They should be comfortable and stabilize the foot, in particular acting to decrease or even prevent supination and pronation tendencies during rolling of the foot when said foot is in contact with the ground. They should also absorb the energ...

AI Technical Summary

Benefits of technology

The purpose of this patent is to improve the comfort and shock absorption of shoes by designing a special shoe sole. This design should help to distribute impact forces evenly across the foot and reduce the pressure on the foot while walking or running. It should also match the natural movement of the foot, depending on the person's weight and the type of foot roll they have.

Problems solved by technology

In US 2003 / 0061731, the contact interface has the drawback of centralizing the impact forces and thereby stiffening the intermediate portions of the top and bottom elements, and this can be uncomfortable, in particular with regard to the calcaneum (heel bone).
