    摘要: An article of footwear (10) includes a sole structure (300, 30) including a chamber (40, 50, 51) for receiving a pressurized fluid, the chamber (40, 50, 51) having a top portion (51), a bottom portion (52), and side portions (53) around a periphery of the chamber (40, 50, 51). The sole structure (300, 30) also includes a central structure (70, 74, 75, 76, 80, 90) located in a central portion of the chamber (40, 50, 51) between opposing side portions (53) of the chamber (40, 50, 51), such that the chamber (40, 50, 51) is devoid of additional structures in a surrounding region (71) around the central structure (70, 74, 75, 76, 80, 90) and extending from the central structure (70, 74, 75, 76, 80, 90) to the side portions (53) of the chamber (40, 50, 51). On all sides (14) of the central structure (70, 74, 75, 76, 80, 90), a dimension (72, 78) of the surrounding region (71) between the central structure (70, 74, 75, 76, 80, 90) and the nearest side portion (53) is one third or more of a span (73) across the chamber (40, 50, 51) between opposing side portions (53).

    摘要: The present invention refers to an article comprising a cushioning assembly that comprises a first bladder element forming a first fluid chamber. The cushioning assembly further comprises a second bladder element within the first bladder element. The second bladder element forms a second fluid chamber sealed from and within the first fluid chamber. At least one reinforcement element is operatively connected to and in contact with at least one of the first bladder element and the second bladder element. The at least one reinforcement element is configured to reinforce the cushioning assembly under a load applied to the first bladder element. Further, the article comprises a sole layer. The first bladder element is secured to the sole layer. The at least one reinforcement element is secured to the sole layer and is pivotable about a first pivot axis as a fulcrum. The at least one reinforcement element comprises a first reaction surface that contacts a first portion of an outer surface of the first bladder element when the at least one reinforcement element is pivoted about the first pivot axis. Further, the present invention relates to a method for manufacturing an article of footwear.
