Abstract
An article of footwear includes an outsole having first and second treads constructed from a first material and defining first and second ground contacting surfaces. The second tread includes a layer of a second material below the first material, the second material being less abrasion resistant than the first material. The second ground contacting surface of the second tread extends below the first ground contacting surface of the first tread. The second tread is configured to move upward when the second ground contacting surface engages a ground surface to distribute a ground force upon both the first tread and the second tread. The second material of the second tread is abraded by the ground surface less than it would have been had the second tread remained at the second distance upon application of the ground force.
