  • Article of footwear having a fluid-filled chamber with flexion zones
    Patent number: 7752772
    Abstract: 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. In other configurations, the chamber may include a chamber secured within a depression of a midsole of the footwear.

  • Fluid system having an expandable pump chamber
    Patent number: 7451554
    Abstract: A fluid system for an article of footwear or other products is disclosed. In one aspect of the invention, the fluid system includes a pump chamber and a pressure chamber. The pump chamber is formed to exhibit a four layer structure to imparts an expandable configuration. The four layers are bonded to each other such that the sidewall has a zigzag-shaped configuration. In another aspect of the invention, the fluid system includes two pump chambers and a pressure chamber in order to increase the resulting pressure in the pressure chamber. In yet another aspect of the invention, at least one of the two pump chambers has an expandable configuration.
