Abstract
Abstract An athletic shoe generally has a plurality of strips of an inextensible material, such as graphite, which extend from the lace area rearwardly over the shoe exterior and into a non-ground contacting area of a laminated sole. The weight of the wearer also bears upon the strip sole ends and aids in retarding movement thereof. The shoe has good forward as well as lateral stability.
