Abstract
A foot heel massaging device is located in the heel of a shoe to massage the foot heel of a person wearing the shoe. The device consists essentially of a fixed member located fixedly in the shoe heel, a movable member located movably on the fixed member and provided with a plurality of massaging knobs, a confining member for confining the fixed member and the movable member, and two magnets located respectively in the fixed member and the movable member such that the like magnetic poles of the two magnets are opposite to each other to bring about a repulsion force to cause the movable member to move away from the fixed member at the time when the movable member is relieved of an external force exerting thereon.
