An article of footwear has an upper and a sole structure secured to the upper. The sole structure includes a chamber that encloses a pressurized fluid. The chamber includes subchambers laterally extending in a medial to lateral direction of the bladder. A bottom surface of the chamber may include at least one bond that laterally extends across the bottom surface of the chamber from one side edge to another side edge of the chamber in the medial to lateral direction. The bond may cooperate with an indentation in the bottom surface that separates one subchamber from an adjacent subchamber. A diameter of the subchambers may decrease in a direction from a heel region of the bladder to a forefoot region of the chamber.

A footwear sole structure may include a plurality of discrete hexagonally-shaped sole elements defined by a plurality of sipes. The sipes may include a plurality of sipes that extend in a transverse direction across the sole structure and a plurality of sipes that extend in an oblique direction relative to the transverse sipes. A plurality of sipes may also subdivide the hexagonally-shaped sole elements into one or more diamond-shaped sole element portions. The sole structure may include additional features such as non-hexagonal sole elements and lugs distributed across a bottom surface of the sole structure.
