CA 2661254

An impact absorbing material for a footwear article includes a first sheet having a plurality of projections for dispersing the force of an impact and a second sheet, having a lower durometer than the first sheet, that is bonded to the first sheet for absorbing the force from the projections. The projections are arranged on the first sheet such that nonlinear gaps are formed between adjacent pairs of projections. The impact absorbing material may be positioned between an upper and an inner liner of the footwear article and may be selectively positioned on the footwear article to protect an area on the wearer that is vulnerable to impact, such as the wearer's feet, ankles, heels or calves.

Matériau absorbant les chocs pour des chaussures, qui comprend une première couche munie de plusieurs projections pour disperser la force d'un impact, ainsi qu'une seconde couche ayant une dureté au duromètre inférieure à la première couche, qui est liée à la première couche pour absorber la force des projections. Ces dernières sont disposées sur la première couche de façon à former des écarts non linéaires entre des paires de projections adjacentes. Le matériau absorbant les impacts peut être placé entre une couche supérieure et une couche inférieure de la chaussure, et peut être placée de façon sélective sur la chaussure afin de protéger sur le porteur des chaussures une zone qui est vulnérable aux impacts, par exemple les pieds, les chevilles, les talons ou les mollets.
