Abstract
Foot support systems include a fluid flow control system that facilitates movement of fluid into, out of, and/or within a sole structure and/or article of footwear, e.g., to change and/or control pressure in fluid filled bladder(s). The fluid flow control system includes: (a) a manifold body defining an internal chamber; (b) at least a first port in fluid communication with the internal chamber; (c) at least a first valve (including a first valve activator) controlling fluid flow through the first port; and (d) a movable cam at least partially within the internal chamber. Valve activator surface(s) on the cam interact with the valve activator(s) to selectively open and close valve(s) based on cam positioning.
