Definitions

  • the present invention relates to a shoe sole suitable for walking, for example, elderly people with low muscular strength.

Abstract

L'invention concerne une semelle de chaussure qui définit une rainure longitudinale avant qui s'étend au moins longitudinalement entre un côté intérieur et un côté extérieur d'une partie de pied avant, et une première rainure de flexion qui est disposée à l'avant de la boule du gros orteil de la partie de pied avant et qui s'étend au moins transversalement de façon à croiser la rainure longitudinale avant au niveau d'un premier point d'intersection imaginaire. Un second angle entre une partie de flexion extérieure de la première rainure de flexion et la rainure longitudinale avant est plus grand qu'un premier angle entre une partie de flexion intérieure de la première rainure de flexion et la rainure longitudinale avant.
