摘要

An article of footwear is provided having an elevated plate structure incorporated in the sole structure and optionally including a fluid-filled chamber. The elevated plate structure can include an upper plate and a plurality of legs extending downward toward the outsole. End portions of the legs can engage an upper region of the outsole. The elevated plate structure can form a cage region that can optionally include a fluid-filled chamber substantially disposed therein. The elevated plate structure can further include a lower plate disposed at an upper region of the outsole, which can form a lower portion of the cage region. Portions of the legs can be integrated with impact-attenuating members in the heel region in various configurations and can provide features for the impact-attenuating members, such as support, impact-attenuation and adjustable impact-attenuation features.
