Abstract (en)
[origin: WO9857562A1] A three dimensional shoe vamp air cushion (1, 20) having an upper sheet and a lower sheet, with all pheripheral edges sealed to form a hollow interior. An upper area of the air cushion is larger than the interior area, permitting the air cushion body to have three dimensions instead of two dimensions. The three dimensional shoe vamp air cushion has one or more air chambers and a similar curvature as the upper surface of a foot, so as to have excellent adaptability and shock absorbing characteristics.
