Abstract
Abstract An athletic shoe, especially a jogging shoe, consisting of a tread sole made of rubber or a rubber-like synthetic resin, which sole is provided at least partially with cleat-like projections distributed over the tread surface and provided at the rim of the sole with additional cleat-like projections subdivided in the manner of a link chain. To create a fully elastic athletic shoe for jogging or other training purposes, wherein the cleat-like projections are to have a relatively low height in order to save weight, wherein yet a satisfactory gripping effect is to be ensured even under unfavorable ground conditions, the cleat-like projections are fashioned, on their sides which come into contact with the ground, with blade-like projections extending essentially in parallel to one another, which increase the shock-absorbing effect and simultaneously enhance the gripping effect.
