Problems solved by technology

[0006] However, these methods of adding to soles are not entirely satisfactory in that the addition of cushioning inserts increases the cost and manufacturing time of the sole, not least due to the difficulty of assembling said inserts to the sole
[0007] In addition, the materials used to form such inserts do not always meet the comfort indicators of the sole, especially those related to the weight and / or durability of the cushioning of said sole
In particular, EVA is a very light and absorbent material, but is not durable and is expensive, while polyurethane is more resistant to abrasion, but is heavier

Embodiment Construction

[0013] A sole for a shoe, in particular a walking shoe that can be worn on a daily basis, is described below with reference to these figures. In particular, the sole can be molded from a wear-resistant and abrasion-resistant synthetic material, for example an elastomer such as rubber, or a material based on PVC.

[0014] The sole has a lower surface 1 which is intended to rest on the ground and which may have a structure facilitating attachment, for example, grooved by transverse and longitudinal grooves of variable depth at different intervals, especially depending on the use of the shoe. As a variant, the lower surface 1 can be covered with a material that improves adhesion and / or limits the wear of the sole, for example a layer of thermoplastic polyurethane (TPU).

[0015] Opposite the lower surface, the sole has an underlying surface 2 comprising a stiff net of said sole, which is also arranged to limit the weight of said sole. To this end, the rigid mesh comprises some r...

Abstract

The invention relates to a shoe sole comprising a base surface (2) whereon alveolar shapes (4) are formed, that are defined by radial walls (3) projecting from the surface, said walls being interconnected in order to form a network for rigidifying said sole, said rigidifying network comprising an area wherein said walls are interrupted in order to form segments (9) that are each formed by a portion of the wall (3) defined by recesses (10), said segments being arranged such that they are able to deform in order to create a sub-network for shock absorbency when contact is made with the ground.

Description

technical field [0001] The invention relates to soles, in particular midsoles, for shoes, in particular walking shoes for everyday wear, which may be injection molded from synthetic materials, for example based on elastomers or polyvinyl chloride (PVC) synthetic material. Background technique [0002] In order to ensure the rigidity of such a sole against twisting and / or bending, a monolithic sole is known from document FR-2 800 581, which has a lower surface on which some radial walls formed by interconnecting are formed. Honeycomb shaped to form the hard stiff mesh of the sole. [0003] However, the stiff mesh also brings compression stiffness which does not provide sufficient cushioning for the wearer to walk comfortably against the impact of the foot against the ground. [0004] In order to solve this cushioning problem, document FR-2 800 581 proposes to provide a clean sole on a rigid net that can absorb shocks when placed against the ground. It is also known to equi...
