ABSTRACT:
The present invention relates to the shoe soles of running shoes, particularly to running shoes used in sports in which bursts of speed are required, e.g., the 100-meter footrace or the approach run for the long jump. The object of the invention is to prevent the heel from touching ground during running and thereby prevent a decrease in running efficiency. A shoe sole for running shoes, therefore, has a forefoot portion which is thickly formed so as to allow for fixing of spikes. Behind the forefoot portion, a reinforcing member is provided to fill the region between the ground contact plane which is the same as the forefoot portion and the bottom surface of the last. A lateral rib and a medial rib are provided to the arch region. The lateral rib possesses a gradually inclined plane, the range thereof beginning from the rear edge portion of the reinforcing member provided to the ball region and extending to the front edge portion of the heel region. The medial rib possesses a gradually inclined plane, the range thereof beginning from the rear edge portion of the reinforcing member provided to the ball region and extending to the front edge portion of the heel region.
