Foot Support Systems, Sole Structures, and Articles of Footwear Including Interconnected Bladder Chambers for Inducing Tilt

Abstract:

Sole structures, foot support systems, articles of footwear, and/or other devices include movable fluid that induces foot tilt, e.g., forefoot tilt. These components may include first and second side foot support bladder chambers; a fluid flow control system that moves fluid through each of first and second fluid flow paths; a first fluid line connecting the fluid flow control system with the first side foot support bladder chamber; and a second fluid line connecting the fluid flow control system with the second side foot support bladder chamber. In the first fluid flow path, fluid moves from the first side foot support bladder chamber to the second side foot support bladder chamber through the fluid flow control system. In the second fluid flow path, fluid moves from the second side foot support bladder chamber to the first side foot support bladder chamber through the fluid flow control system.
