Abstract: A plurality of fluid-filled chambers may be incorporated into sole structures of articles of footwear. The chambers may be configured to be substantially diamond-shaped. The chambers may lie within cavities formed by a lower surface of the midsole and may extend into apertures in the outsole. The apertures in the outsole may be aligned with the cavities of the midsole. The chambers may be bounded by bounding regions between and at the perimeter of the chambers. The bounding regions may be formed of a polymer foam material of the midsole. The chambers may additionally be connected.

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.
