Abstract

L'invention concerne une semelle de chaussure (1) comprenant une chambre souple (6) intérieure qui présente au moins un orifice d'entrée (5) et au moins un orifice de sortie (9). Ladite semelle de chaussure (1) comprend en outre une soupape d'entrée (15) associée à l'orifice d'entrée (5) et une soupape de sortie (19) associée à l'orifice de sortie (9), la chambre souple (6) étant disposée dans la région de l'avant-pied de la semelle de chaussure (1), où se trouve également une chambre d'entrée d'air (4) de la semelle de chaussure (1). La chambre d'entrée d'air (4) est reliée par la soupape d'entrée à la chambre (6) qui est ouverte sur l'environnement par des ouvertures (2) ménagées dans la première (3). Par ailleurs, la chambre (6) est reliée par la soupape de sortie à l'orifice de sortie (9) situé sur le côté extérieur de la semelle (1), en dehors de la première (3). La chambre (6) est essentiellement entièrement remplie d'une matière élastiquement déformable (16) conçue de manière que lors de sa dilation élastique, elle aspire de l'air et que lors de sa compression, elle rejette l'air absorbé précédemment. De cette façon, on peut obtenir dans la chaussure équipée de cette semelle une circulation d'air qui est agréable pour le pied.
