  • the present invention mainly relates to a shoe midsole, and more particularly, to a midsole having a structure capable of dispersing the pressure applied to the sole in a heeled women's shoes.
  • the foot is an elaborate and delicate organ composed of many bones, joints, ligaments and numerous muscles and tendons.

  • the high heels have a forefoot with a sole that touches the ground even when the user moves or stops, and a rear foot (heel) spaced a certain distance from the ground by a high heel, so that the inclination of the bottom of the shoe is inevitable, Due to the inclination of the portion connecting the forefoot and the forefoot, the forefoot of the foot is not stable on the shoe and is always forced to the front of the shoe along the inclination of the inner surface of the shoe. By this force, the user's weight is concentrated on the heel, and the narrow cheeks in front of the shoe are likely to cause hallux valgus.

Abstract

L'invention concerne un coussin de semelle intercalaire pour chaussure pour femme qui couvre la zone allant de l'extrémité arrière du pied à l'extrémité arrière du devant du pied. La courbure (S) formée dans la direction longitudinale du pied le long d'une surface supérieure du coussin présente une partie bombée vers le haut à partir de la ligne droite à l'interconnexion des deux extrémités du coussin protecteur dans la direction longitudinale. Le point culminant (X) de la partie bombée qui constitue le point auquel la partie bombée présente la voussure la plus prononcée et éloignée de ladite ligne droite est positionné plus en avant (en direction de l'avant du pied) que le point auquel la ligne partant perpendiculairement du demi-point (M) de la ligne droite rejoint la courbure (S). Selon l'invention, la partie de la semelle de chaussure pour femme qui interconnecte l'extrémité arrière de la semelle de chaussure à distance du sol et une partie de la semelle de chaussure en contact avec le sol présente un degré d'inclinaison variable de manière à permettre au talon du pied d'une personne portant ladite chaussure d'être positionné à plat dans la direction horizontale, ce qui permet de répartir sur la partie talon du pied de la personne portant la chaussure, la pression exercée sur l'avant du pied et la partie du gros orteil de la personne portant la chaussure, sous l'effet du poids de la personne portant la chaussure, avec pour effet de réduire efficacement la pression exercée.
