Abstract
A profiled outer sole for shoes made of a material having rubber-elastic properties with the sole including a tread surface having a front tread end portion, rear tread end portion, a profiled middle area and profiled marginal areas arranged on respective sides of the middle area. The front tread end portion, the rear tread end portion and each of the marginal areas include outer edges adjoining the tread surface to a shell rim of the outer sole with each of the outer edges being rounded with a predetermined radius. The marginal areas define foundation strips having spaced block-shaped profiled projections enclosing box-shaped profiled projections with a number of groove-shaped slots being substantially uniformly distributed along each of the foundation strips.
