Abstract

L'invention concerne une chaussure à amortissement par ressort capable de bien absorber les chocs afin de soulager la pression sur le pied pendant tout le cycle de marche d'un porteur qui permet d'éviter que le pied de l'utilisateur et la partie supérieure du corps principal de la chaussure soient inclinés rapidement d'un côté à l'autre en installant un coussin d'air sur une partie circonférentielle extérieure d'un ressort entre le corps principal de la semelle de la chaussure et une semelle extérieure au niveau du talon de la chaussure. Comme les surfaces supérieures et inférieures du coussin d'air sont respectivement des surfaces plates afin d'augmenter la surface de contact entre le corps principal de la semelle de la chaussure, le coussin d'air et la semelle extérieure, le coussin d'air peut être fixé fermement au corps principal de la semelle de la chaussure et à la semelle extérieure dans sa position normale.
