<p>A shoe sole construction designed so as to be biodynamically shock-absorbing.</p><p>In the sole (2) are provided two cushions (8, 9) which are filled with a fluid (10) and interconnected by means of a number of channels (11). One cushion (8) is positioned underneath the heel (6) of the foot and the other cushion (9) is positioned underneath the transverse forward arch (7) of the foot.</p><p>When 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 (8) to the front cushion (9), which expands and lifts the front arch of the foot, releaving the weight thereon and supporting the front arch when the forefoot is set down on the ground. When the wearer continues the walking cycle, the forward cushion (9) is compressed, causing the rear cushion (8) to expand and the latter is again ready to provide a shock-absorbing effect upon the next step and heel strike.</p> |
