Abstract
A cushioning device for high heel shoes includes a layer of energy field generators producing electric/magnetic fields, and a chamber filled with an ER/MR fluid. The strengths of electric/magnetic fields are positioned in preassigned locations of the layer, according to the pressure distribution of foot. The viscosity of the ER/MR fluid can be adjusted by different strengths of electric/magnetic fields, so that different locations of foot can receive different supports from the cushioning device to enhance the comfort.
