Abstract

A fluid-filled chamber (40) for an article of footwear and a method for manufacturing the chamber are disclosed. The chamber may be incorporated int o a sole structure (30) of the footwear and includes a central area (41) and a plurality of lobes (42a-42e) extending outward from the central area. The lobes are in fluid communication with the central area and are formed from a first surface (45), a second surface (46), and a sidewall (47). The sidewall joins with the first surface with the second surface to seal the fluid withi n the chamber, but no internal connections are generally utilized to join interior portions of the first surface with interior portions of the second surface. The fluid within the chamber may be air at a pressure that is approximately equal to an ambient pressure.
