Abstract

La présente invention concerne une semelle intérieure antidérapante pour athlètes. La semelle intérieure antidérapante pour athlètes selon la présente invention comprend : une couche antidérapante (10) comportant des rainures antidérapantes (14) formées sur une surface supérieure de celle-ci en permettant l'élimination d'une surface supérieure d'une couche d'uréthane humide (10a) de telle sorte que des cellules supérieures (11) de la surface de couche soient exposées ; une couche de mousse d'uréthane poreuse (20) ; et une couche inférieure (30) constituée d'un matériau non perméable. Selon la présente invention, dans le cas d'athlètes dans des sports rapides ou des sports dans lesquels un atterrissage sûr est important, et dans des sports professionnels impliquant une longue distance de marche, la semelle peut contribuer à la prévention de blessures sans affecter leurs performances.
