Tread sole for athletic shoe consisting of rubber or another material having rubber-elastic properties
First Claim
1. Tread sole for athletic shoes comprised of rubber or like material having rubber-elastic properties, said sole being provided with nubs uniformly distributed over at least a portion of the tread and forming a unit with the tread sole, some of the nubs being oriented, as a whole, obliquely to the sole surface, characterized by the combination of the following features:
- (a) the obliquely oriented nubs are arranged exclusively along a rim of the sole in zones of the sole corresponding to the ball, the ankle joint, and the heel region of a foot as at least one outermost row of nubs;
(b) some of the nubs being provided in a marginal zone of the toe of the sole, said marginal zone nubs being arranged with their longitudinal axes substantially perpendicular to the sole tread and having a smaller profile height than the obliquely oriented nubs; and
(c) expansion grooves being located in a frontal region of the sole starting approximately from the zone of the ankle joint and extending forwardly up into the marginal zone of the toe of the sole.

Abstract
Athletic shoes, especially soccer shoes are known comprising a tread sole of rubber or another material having rubber-elastic properties, which sole is provided at least partially with nubs uniformly distributed over the tread and forming a unit with the tread sole, the longitudinal axes of these nubs being aligned obliquely with respect to the sole surface. In order to broaden the area of usage of such athletic shoes, especially to render such athletic shoes suitable for sports on artificial grass or on hard courts, the obliquely oriented nubs are arranged exclusively in the areas of the ball of the foot, the ankle joint, and the heel along the rim of the sole as the outermost nub row or as external nub rows. The nubs located in the marginal zone of the tip of the sole are arranged with their longitudinal axes at least almost perpendicular with respect to the sole tread and exhibit a lower profile height than the obliquely oriented nubs. Expansion grooves extending up into the marginal zone of the tip of the sole are arranged in the forward area of the sole starting approximately from the ankle joint, in order to impart to the tread sole of such athletic shoes an increased flexibility transversely over the tread sole surface.
