Abstract

La présente invention concerne une chaussure pour hallux valgus (1) servant à traiter au moins une désaxation des os du gros orteil et du milieu du pied, ladite chaussure comprenant un élément de semelle (2) pourvu d'une semelle de marche (2.1) et d'une semelle intérieure (2.2), d'une section à boucle pour le gros orteil (3) servant à maintenir en place latéralement le gros orteil, et d'une section à boucle pour le milieu du pied, laquelle, lors du port de la chaussure, maintient celle-ci sur le pied. En modifiant la longueur d'enroulement de la section à boucle pour le gros orteil (3) et de la section à boucle pour le milieu du pied (4), une force correctrice respective peut être ajustée sur le gros orteil et le milieu du pied. Les deux sections à boucle (3, 4) sont couplées l'une à l'autre de telle sorte qu'une force correctrice du milieu du pied agissant latéralement sur le milieu du pied puisse être modifiée en changeant la longueur d'enroulement de la section à boucle pour le milieu du pied (4), qui presse le milieu du pied situé sur la face interne du pied dans une direction latérale vers la face externe du pied et au moyen duquel, lorsque la section de la boucle pour le milieu du pied (4) est couplée à la section à boucle pour le gros orteil (3) disposée à l'intérieur de la semelle extérieure, cette dernière est également serrée en même temps, ce qui permet d'exercer simultanément une force correctrice du gros orteil sur la face interne du pied. La section à boucle pour le gros orteil (3) est guidée en biais du gros orteil vers l'arrière et pénètre dans un canal (16) sur la face intérieure de l'élément de semelle (2) qui est disposé dans la zone du milieu du pied de la sandale (1).
