1. A foot support system for an article of footwear, comprising:
a foot support bladder;
a fluid container;
a fluid supply;
a valve housing;
a valve stem movably mounted in the valve housing, wherein the valve stem includes a first end, a second end, and a perimeter wall extending between the first end and the second end, wherein the first end, the second end, and the perimeter wall define an internal chamber of the valve stem, and wherein the perimeter wall of the valve stem includes a plurality of through holes extending from the internal chamber to an exterior surface of the perimeter wall;
a fluid inlet port placing the fluid supply in fluid communication with the internal chamber; and
a manifold including: (a) a first manifold port in fluid communication with an external environment and opening into a first fluid flow path extending through the manifold, (b) a second manifold port in fluid communication with the foot support bladder and opening into a second fluid flow path extending through the manifold, and (c) a third manifold port in fluid communication with the fluid container and opening into a third fluid flow path extending through the manifold,
wherein movement of the valve stem to a plurality of positions selectively places the foot support system in a plurality of operational states by placing one or more of the plurality of through holes of the valve stem in fluid communication with the first fluid flow path, the second fluid flow path, or the third fluid flow path.
