Abstract

Fluid systems, foot support systems (including sole structures), and/or articles of footwear include: (a) a foot support bladder; (b) a fluid reservoir; (c) a pump (e.g., a foot-activated pump) including an inlet and an outlet, the outlet supplying fluid to one of the fluid reservoir or the foot support bladder; (d) a fluid line placing the foot support bladder or the fluid reservoir in fluid communication with the inlet of the pump; and (e) another fluid line placing the foot support bladder in fluid communication with the fluid reservoir. Such fluid systems, foot support systems, and/or articles of footwear further may include an electronic control system (e.g., an electronically controlled switch or valve), e.g., for changing at least one of the fluid lines between an open configuration and a closed configuration. The electronic control system may receive user input for adjusting foot support pressure (e.g., from a mobile electronic device).
