Abstract
A sole structure for an article of footwear may include a perimeter element and a central element, which may be fluid-filled chambers. The perimeter element extends adjacent to a sidewall of the sole structure, and the central element is centrally-positioned. A gap may extend between the central element and the perimeter element. The gap may have an upper portion and a lower portion, with the upper portion being located closer to the sidewall than the lower portion. The perimeter element may also have a first compressibility and the central element may have a second compressibility, with the first compressibility being less than the second compressibility. Also, the upper surface of the perimeter element may be at a greater elevation or higher than an upper surface of the central element.
