Sole structure with electrically controllable damping element

Abstract:

A sole structure may include a damping pad. The damping pad may include a chamber, a foam element located within the chamber, an electrorheological fluid located within the chamber and at least partially permeating the foam element, and a set of electrodes positioned to create, in response to a voltage across the electrodes, an electrical field in at least a portion of the electrorheological fluid.
