Support members with variable viscosity fluid for footwear

An article of footwear including an adaptive support system includes a plurality of support members. Each support member includes an outer chamber and an inner chamber, the inner chamber being filled with a magnetorheological fluid. An electromagnet is disposed adjacent to the inner chamber and can be used to vary the viscosity of the magnetorheological fluid.

Fluid-filled chamber with stitched tensile member

A chamber for receiving a pressurized fluid may include a tensile member extending between a first chamber barrier layer and a second chamber barrier layer and including a plurality of tethers extending between the first tensile member layer and the second tensile member layer. The chamber may include stitching through the tensile member in a stitched region. When the chamber is pressurized with the pressurized fluid, a substantial majority of the first tensile member layer is separated from the second tensile member layer by a distance that corresponds to a length of the plurality of tethers. In addition, the first tensile member layer is held in contact with the second tensile member layer by the stitching in the stitched region, thereby forming an area of the chamber having a reduced thickness relative to adjacent portions of the chamber.
