Abstract

L'invention concerne une sandale sans lanières à élément d'écartement des orteils (1), comportant une semelle (10), la semelle (10) comprenant une extrémité côté orteils (11) et une extrémité côté talon (12) ainsi qu'un côté intérieur (14) et un côté extérieur (13). La sandale à élément d'écartement des orteils (1) comporte un élément d'écartement des orteils (3) et une languette (4), l'élément d'écartement des orteils (3) étant disposé plus près de l'extrémité côté orteils (11) que de l'extrémité côté talon (12) de la semelle. L'élément d'écartement des orteils (3) comprend une première extrémité (31) d'élément d'écartement des orteils, laquelle est reliée à la semelle (10), et une deuxième extrémité (32) d'élément d'écartement des orteils, laquelle se trouve sensiblement à hauteur des orteils et porte la languette (4), l'élément d'écartement des orteils (3) étant, lors de l'utilisation correcte de la sandale à élément d'écartement des orteils, disposé de manière à être reçu dans l'espace intermédiaire entre deux orteils adjacents du porteur. La languette (4) recouvre le pied au moins partiellement lors de l'utilisation correcte de la sandale à élément d'écartement des orteils, de telle sorte que la largeur maximale de la languette (4) soit supérieure à la largeur maximale de la deuxième extrémité (31) d'élément d'écartement des orteils. L'élément d'écartement des orteils comprend un côté avant (33) et un côté arrière (34), le côté avant (33) étant orienté en direction de l'extrémité côté orteils (11), le côté arrière (34) étant orienté en direction de l'extrémité côté talon (12) et l'étendue entre le côté avant (33) et le côté arrière (34) étant définie comme la direction longitudinale, laquelle est située parallèlement à la longueur de semelle L. Le côté arrière (34) s'étend entre la première extrémité (31) d'élément d'écartement des orteils et la deuxième extrémité (32) d'élément d'écartement des orteils, le côté arrière (34) comprenant au moins un point de mesure (39) situé à une distance minimale a de l'extrémité côté orteils (11), la distance minimale a étant mesurée dans un premier plan parallèle (6) par rapport à la surface de semelle (16). Le premier plan parallèle (6) passe par le point de mesure (39). Une distance b est définie entre le point de mesure (39) et un point de languette (45), laquelle distance représente, en projection sur le premier plan parallèle (6), la plus grande distance à l'extrémité côté orteils (11), la distance b valant au moins 2,5 % de la longueur de semelle L.
