1. A footwear foot support system, comprising:
a foot support bladder;
a fluid source comprising a foot-activated pump;
a manifold body defining an internal chamber;
a first port placing the fluid source in fluid communication with the internal chamber;
a second port in fluid communication with the foot support bladder 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 chance 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 activator e 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, throat the first port, through the internal chamber of the manifold body, through the second port, and into the foot support bladder.
