An article comprises a chamber (100, 1143, 200, 300, 33, 400, 500, 600, 700, 800) that includes a barrier (110, 210, 310, 402, 40, 502, 802) formed from a polymer material. The barrier (110, 210, 310, 402, 40, 502, 802) has a first portion (412, 512, 804, 812) that forms a first surface (805) of the chamber (100, 1143, 200, 300, 33, 400, 500, 600, 700, 800), and a second portion (414, 514, 806, 814) that forms an opposite second surface (807) of the chamber (100, 1143, 200, 300, 33, 400, 500, 600, 700, 800). The barrier (110, 210, 310, 402, 40, 502, 802) includes a bond (45, 809A) that secures the first portion (412, 512, 804, 812) of the barrier (110, 210, 310, 402, 40, 502, 802) and the second portion (414, 514, 806, 814) of the barrier (110, 210, 310, 402, 40, 502, 802) to one another and separates the barrier (110, 210, 310, 402, 40, 502, 802) into a first interior cavity (410A, 510A, 810A) and a second interior cavity (410B, 510B, 510C, 810B) that retain fluid, with the second interior cavity (410B, 510B, 510C, 810B) extending only in the forefoot region (11, 12, 2111) forward of the first interior cavity (410A, 510A, 810A). A plurality of tethers (1168, 453A, 453B, 453C, 53, 553A, 553B, 553C, 63, 853A, 853B, 853C) are in each of the first interior cavity (410A, 510A, 810A) and the second interior cavity (410B, 510B, 510C, 810B) and operatively connect the first portion (412, 512, 804, 812) to the second portion (414, 514, 806, 814). |
