Claim 16:
17. A footwear foot support system, comprising:
a foot-activated pump;
a fluid filled bladder reservoir;
a manifold body defining an internal chamber;
a first port placing the foot-activated pump in fluid communication with the internal chamber;
a second port in fluid communication with the fluid filled bladder reservoir and the internal chamber;
a first valve controlling fluid flow through the first port, wherein the first valve includes a first valve activator;
a second valve controlling fluid flow through the second port, wherein the second valve includes a second valve activator; and
a movable cam at least partially located within the internal chamber, wherein the movable cam includes: (i) one or more first valve activator surfaces that interact with the first valve activator to change the first valve between a closed configuration and an open configuration and (ii) one or more second valve activator surfaces that interact with the second valve activator to change the second valve between a closed configuration and an open configuration,
wherein in a first operational state, the movable cam is positioned such that: (a) at least one first valve activator surface interacts with the first valve activator to place the first valve in the open configuration and (b) at least one second valve activator surface interacts with the second valve activator to place the second valve in the open configuration, and wherein in this first operational state, fluid flows from the foot-activated pump, through the first port, through the internal chamber of the manifold body, through the second port, and into the fluid filled bladder reservoir.
