Abstract

See full text

An energy return device for footwear has a flattenable conical disk with a ring spring arranged around the base of the conical disk. A rigid upper heel-receiving plate is connected to the apex of the flattenable conical disk. The heel-receiving plate may be rigidly or semi-rigidly attached to the apex of the conical disk to stabilize an angle of the heel-receiving plate. There may be a conical damping disk between a lower surface of the heel-receiving plate and an upper surface of the conical disk. There may be protrusions on the bottom of the heel-receiving plate which interact with pockets in the upper surface of the conical disk, for example distorting the conical damping disk. There may be viscoelastic inserts in the pockets, for example providing damping in place of or in addition to the damping disk.
