First Claim
1. An outer sole for an athletic shoe comprising:
- a base formed of a relatively thin resilient material and having a heel section, an arch section, a forefoot section, a toe section, an upper major surface and a lower major surface;
a plurality of discrete traction elements extending downward from said lower major surface of said base at spaced transverse and longitudinal locations including a plurality of discrete heel and arch traction elements located about longitudinally spaced locations adjacent the perimeter of said base in said heel and arch sections respectively;
a rear shock attenuating area extending generally along the central longitudinal portion of said heel and arch sections, said rear shock attenuating area being substantially devoid of traction elements so that the relatively thin resilient material of said base in said rear shock attenuating area depresses downwardly during foot strike to attenuate the force of foot strike.

Abstract
An outer sole for an athletic shoe is disclosed. The outer sole includes a base formed of a relatively thin resilient material and having a heel section, an arch section, a forefoot section, a toe section, an upper major surface and a lower major surface. A plurality of discrete traction elements extend downward from the lower major surface of the base at spaced transverse and longitudinal locations, and include a plurality of discrete heel and arch traction elements located about longitudinally spaced locations in the perimeter of base in the heel and arch sections respectively. A rear shock attenuating area extends generally along the central longitudinal portion of the heel and arch sections. The rear shock attenuating area is substantially devoid of traction elements so that the relatively thin resilient material of the base in the rear shock attenuating area depresses downwardly during foot strike to attenuate the force of foot strike.

27. An outer sole for an athletic shoe comprising:
-
a base formed of a relatively thin resilient material and having a heel section, an arch section, a forefoot section, a toe section, an upper major surface and a lower major surface; a plurality of traction elements extending downwardly from said lower major surface of said base at transversely and longitudinally spaced locations within said heel, arch and forefoot sections, said traction elements including polygonal cleats in a portion of said heel section and in said arch and heel sections and wear plugs having ground engaging surface areas substantially greater than the average ground engaging surface area of the polygonal cleats, said wear plugs being located about the rear and lateral and medial sides of said heel section, said wear plugs having ridges extending substantially perpendicular to the line at which a runner typically abducts, said polygonal cleats in said heel and arch sections having a side wall along the inner side of the cleats extending from an inner ground engaging edge of the cleats toward a longitudinal center of said base to form a reinforcing wedge between the inner ground engaging edge of the cleats and said base; a rear shock attenuating area extending generally along the central longitudinal portion of said heel and arch sections, said rear shock attenuating area being substantially devoid of traction elements; a front shock attenuating area extending generally along the central longitudinal portion of said forefoot section, the polygonal cleats in said front shock attenuating area being thinner than the polygonal cleats along the medial and lateral perimeter of said forefoot section so that the relatively thin resilient material of the base in the front and rear shock attenuating areas depresses downwardly during foot strike to attenuate the force of foot strike.
