In the sole are provided two cushions which are filled with a fluid and interconnected by means of a number of channels. One cushion is positioned underneath the heel of the foot and the other cushion is positioned underneath the transverse forward arch of the foot. Wen the wearer of the shoe sets down his foot into contact with the ground, the heel strikes the ground first and a shock-absorbing effect is then obtained as the rear cushion is compressed. Upon this compression, fluid flows from the rear cushion to the front cushion, which expands and lifts the front arch of the foot, releaving the weight thereon and supporting the front arch when the forefoot is setdown on the ground.
