Abstract

An athletic shoe particularly adapted to support the foot while the wearer is running, and having a particular cleat configuration on the sole for contacting the ground or running surface in a manner to both cushion the foot and leg of the wearer and provide improved traction as the heel strikes the surface.

Claims

1. An athletic shoe comprising in combination:

a shoe upper portion having heel, shank and toe areas and forming a cavity for receiving the foot;

a sole attached to said shoe upper portion for supporting the foot on the running surface, said sole comprising;

a cushioning pad of resilient material fixed to the upper portion;

a plurality of compressible cleats fixed to the bottom side of said cushioning pad and projecting downward to contact the running surface, said cleats being distributed throughout the area of the sole between the heel and the toe portions of the shoe; and

said cleats at the heel portion of the shoe being of at least two different heights and being intermingled such that the longer cleats will contact the running surface first to provide a first cushioning action and upon compression, will permit the shorter cleats to contact the running surface to provide additional cushioning action for the foot.

2. An athletic shoe as defined in claim 1 wherein said cleats are of a truncated cone configuration with the area of smaller diameter extending downward to contact the running surface.

3. An athletic shoe as defined in claim 2 wherein at least some of said cleats include stiffening members extending from the sides thereof to enable the cleats to withstand shear forces exerted on the shoes striking the running surface.

4. An athletic shoe comprising in combination:

a shoe upper portion having heel, shank and toe areas and forming a cavity for receiving the foot;

a sole attached to said shoe upper portion for supporting the foot on the running surface, said sole comprising;

a cushioning pad of resilient material fixed to the upper portion;

a plurality of cleats fixed to the bottom side of said cushioning pad and projecting downward to contact the running surface, said cleats being distributed throughout the area of the sole between the heel and the toe portions of the shoe; and

said cleats at the heel portion of the shoe being of at least two different heights and being intermingled such that the longer cleats will contact the running surface first to provide a first cushioning action and upon compression, will permit the shorter cleats to contact the running surface to provide additional cushioning action for the foot; and

a stabilizing layer of resilient material positioned between the upper portion and the cushioning pad and extending along the heel and shank areas and terminating prior to reaching the toe area.

5. An athletic shoe as defined in claim 4 wherein said stabilizing layer is a resilient material having a stiffness exceeding that of the cushioning pad to provide additional support for the foot in the heel and shank areas.

6. An athletic shoe as defined in claim 5 including a heel counter forming the portion of the shoe upper portion enclosing the heel of the shoe to grip the heel of the wearer.

7. An athletic shoe as defined in claim 4 wherein said cleats in the heel portion of the sole are truncated cone-shaped with the larger area positioned adjacent the cushioning pad.
