Abstract
Various arrangements for an article of footwear including an outsole having grooves forming discrete lugs are presented. The outsoles generally include a plurality of grooves formed in at least a portion of the outsole that extend from a lateral side of the outsole to a medial side of the outsole. The grooves may be linear or curved and generally extend in an angular fashion. The grooves may have a first depth at a perimeter of the outsole and a second depth, greater than the first depth, at the center of the outsole. The grooves form discrete lugs. In some arrangements, the lugs are diamond shaped.
