ABSTRACT:
The sports shoe according to the invention has a highly elastic heel which reduces the shock on the foot during running and jogging. The heel which is made of a resilient, elastic material is in the shape of a strip which is arched in dowward direction and connected to the sole at its front end while forming a longitudinal cavity with the sole which is open towards the rear end of the shoe. A spring composed of two leaves which are connected at one end and unconnected at the other end of the spring, are inserted into the cavity with the connected ends positioned at the front end of the cavity and with the unconnected ends close to the rear end of the heel, whereby the upper of the two leaves is connected to the sole and the lower, strongly bent leaf to the arched heal strip. The rear end of the lower leaf is free to slide or to roll along the rear portion of the upper leaf in accordance with the pressure applied to the heel surface during jogging or running, thereby largely increasing the range of compression and decompression of the heel strip resulting in more comfort of the wearer.
