ABSTRACT:
An outsole for an article of footwear having inclined lugs that protrude downwardly from the bottom of the outsole. The outsole defines an undercut around at least a portion of each lug to permit the lugs to collapse into the outsole when walking on hard, flat surfaces. The lugs in the forefoot portion of the outsole are inclined rearwardly and the lugs in the heel portion of the outsole are inclined forwardly. In a second aspect, the outsole includes a plurality of downwardly protruding ridges that undulate around the profile of the outsole in a generally horizontal direction to provide the profile of the outsole with a gripping surface.
