Abstract (en)

[origin: WO9857802A1] A buffer double air cushion adaptable to a shoe vamp includes an outer air cushion (1) and an inner air cushion (2). The outer air cushion (1) and the inner air cushion (2) are inflated to a different inner pressure. An upper surface of both the outer (1) and inner (2) air cushion are curved down to two sides with non-specific curvature. So the buffer double air cushion has a good 3D curvature to closely fit a foot wearing it, and excellent buffer and shock-absorbing function by means of air or gas pressure.
