Claim 14:
15. The footwear foot support system according to claim 12, further comprising:
a foot-activated pump;
a third port in fluid communication with the foot-activated pump and the internal chamber; and
a third valve controlling fluid flow through the third port, wherein the third valve includes a third valve activator,
wherein the movable cam further includes one or more third valve activator surfaces that interact with the third valve activator to change the third valve between a closed configuration and an open configuration,
wherein in a second operational state, the movable cam is positioned such that: (a) no first valve activator surface interacts with the first valve activator to place the first valve in the closed configuration, (b) at least one second valve activator surface interacts with the second valve activator to place the second valve in the open configuration, and (c) at least one third valve activator surface interacts with the third valve activator to place the third valve in the open configuration, and wherein in this second operational state, fluid flows from the foot-activated pump, through the third port, through the internal chamber of the manifold body, through the second port, and to the external environment.
