The shoe product may include an upper forming a cavity in the shoe, a window structure fixed to the upper, and a chamber surrounding the compressed fluid. The window structure includes a recess. The chamber is located within the cavity of the upper and is positioned on the recess of the window structure. The chamber may include a plurality of fluid-filled chambers, a manifold and a connection for fluidly communicating at least one of the sub-chambers in fluid communication with the manifold. The sub-chamber may enrich the pressurized fluid at different pressures. The sub-chambers may be separated from each other by a bonded area in the direction extending between the heel and toe of the chamber. |
