Abstract

An improved athletic shoe is disclosed which is particularly suited for use in the game of baseball. The athletic shoe comprises a sole having an upper secured to it and extending upwardly from its upper side. A first set of cleats extends downwardly from the sole and comprises at least three thin and arcuate cleats. Moreover, this first set of cleats is secured to the ball portion of the sole and positioned in a ring so that each cleat has substantially the same radius and center as each other. A second set of thin and arcuate cleats is also secured to the ball portion of the sole in a ring concentric with the first set of cleats but on a smaller radius than the first set of cleats. The first and second set of cleats provide improved pivoting for the athletic shoe.

Claims

1. An athletic shoe comprising:

a sole,

an upper secured to said sole and extending outwardly from an upper side of the sole,

a first set of at least three narrow and arcuate cleats secured to the forward portion of said sole and extending outwardly from the lower side of said sole, each of said cleats being positioned on said sole on substantially the same radius of curvature and substantially having a common center and

a second set of at least three narrow and arcuate cleats secured to the forward portion of said sole and extending outwardly from said lower side of said sole, said second set of cleats being positioned on said sole concentrically with said first set of cleats but on a radius from said center smaller than said first set of cleats.

2. The invention as defined in claim 1 wherein the cleats in said second set taper away from each other.

4. The invention as defined in claim 1 wherein a front cleat in said first set is positioned adjacent at the forwardmost portion of the sole and wherein one cleat in said second set extends laterally outwardly from a line extending from one end of said front cleat and longitudinally along said sole and wherein a further cleat in said second set extends laterally outwardly from a further line extending from the other end of said front cleat and longitudinally along said sole.

5. The invention as defined in claim 1 a further comprising a rear set of cleats secured to the rear portion of said sole and extending outwardly from the bottom thereof, said rear set of cleats including one cleat extending transversely across the sole adjacent the rearwardmost portion of the sole.
