L'invention concerne une structure de semelle pour un article chaussant, comprenant un composant d'amortissement unitaire comprenant une pluralité de pièces de mousse de rebut configurées en tant qu'une pluralité de formes polyédriques différentes et un liant de résine qui fixe les pièces de mousse de rebut les unes aux autres. La structure de semelle peut comprendre une semelle intercalaire comprenant une enveloppe externe qui définit une cavité centrale. Le composant d'amortissement peut être disposé dans la cavité centrale en tant que noyau de la semelle intercalaire. L'invention concerne également un procédé de fabrication d'un article chaussant comprenant la découpe du corps de mousse de rebut en morceaux, le mélange des morceaux avec un liant de résine, et le moulage par compression des pièces mélangées et du liant de résine dans un moule afin de former un composant d'amortissement d'une structure de semelle de l'article chaussant.
