An article of footwear is disclosed that includes a fluid-filled chamber
with one or more flexion zones. The flexion zones may be areas of the
chamber where a tensile element, for example, is absent, or the flexion
zones may be areas of the chamber where opposite surfaces of the chamber
are bonded together. The footwear may also include a sole structure with
a flexion zone, and the flexion zone of the chamber may be aligned with
the flexion zone of the sole structure.
