An article of footwear having a fluid-filled chamber with flexion zones

摘要

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.
