CA 2050299

his sole, composed of a semi-rigid thermoformable material, is moulded so that it has a profile corresponding to the general shape of the inferior surface of a standard foot; the central part of the exterior edge is designed to press against the shoe upper essentially perpendicularly to it, and the interior edge, which presses against the inner wall of the central part of the stem basically tangentially thereto, is raised above the lower part of the sole, so that the area it delimits creates a raised zone rising smoothly from the lower part of the sole, essentially from the midline thereof to the raised interior edge; the raised zone of the sole is arranged so that, once the sole is placed in the shoe, it will adapt to the shape of the user's foot as a result of the pressure from its weight, by sliding along the upper and pressing tangentially against the sole.

Cette semelle est réalisée en un matériau thermoformable semi-rigide et est obtenue par moulage de façon à présenter un profil correspondant à la forme générale de la surface inférieure d'un pied standard, dont le bord extérieure est destiné, dans sa partie centrale, à prendre appui contre la tige de la chaussure sensiblement perpendiculairement à celle-ci, et dont le bord intérieur, destiné à prendre appui contre la paroi interne de la zone centrale de la tige sensiblement tangentiellement à celle-ci, est surélevé par rapport à la partie basse de la semelle, de telle sorte que la zone qu'il délimite formeune zone suspendue s'élevant régulièrement à partir de la partie basse de la semelle, sensiblement depuis la ligne médiane de celle-ci jusqu'au bord intérieur surélevé, la zone suspendue de la semelle étant agencée pour que, après mise de la semelle dans la chaussure, elle s'adapte à la forme particulière du pied de l'utilisateur sous l'action du poids de celui-ci, par glissement le long de la tige de la zone de la semelle en appui tangentiel contre celle-ci.
