Abstract

La présente invention concerne une semelle de chaussure intermédiaire (2, 3) formée par une structure tridimensionnelle formé par un polymère expansé pour former des cavités fermées, caractérisée en ce que ledit copolymère est un copolymère unique pour l’intégralité de ladite structure tridimensionnelle, et présente une densité décroissant continument dans une direction perpendiculaire à une surface transversale médiane de référence, et en ce que ladite structure tridimensionnelle présente une pluralité de parois intérieures s’étendant entre deux surfaces opposées dans des directions majoritairement inclinées selon un angle compris entre 2° et 30° par rapport à ladite surface transversale médiane de référence et de préférence de 2° à 20°.
