发明名称 Footwear device
摘要 A device for use in footwear to correct and prevent problems associated with the human foot. The device includes upstanding side and rear walls which are integrally joined with a lower wedge to form a heel cup that closely fits with and supports the heel bone with respect to vertical. An upper planar surface of the wedge inclines at a predetermined lateral angle for controlling contact position and movement of the heel bone during locomotion. A support anchor projects forwardly from the wedge and terminates in a pointed distal end which is located toward the medial side of the foot.
