Abstract

Semelle amortissante (10) conçue pour être mise en contact avec un pied présentant un relief spécifique et une répartition caractéristique des points de pression. Cette structure amortissante (10) est composée d'une couche centrale (12) en matériau thermoplastique semblable à du caoutchouc dont une surface supérieure (14) est conçue pour être en contact avec le pied, dont le relief est adapté au relief spécifique du pied et qui présente une surface inférieure (16) située en face de ladite surface supérieure (14). Cette semelle amortissante (10) comprend, de plus, une configuration de doigts anatomiques (20) absorbant la pression, espacés les uns des autres, solidaires de la couche centrale (12) et formant une saillie depuis au moins une desdites surface supérieure (14) et surface inférieure (16). Chacun des doigts (20) présente une hauteur et un diamètre prédéterminés. La configuration, la hauteur et le diamètre de ces doigts (20) sont déterminés en fonction des caractéristiques physiques du matériau thermoplastique et de la répartition spécifique des points de pression du pied, ce qui permet à la totalité de ces doigts (20) de s'adapter à cette répartition.
