US Patent 7603794 Rear balance walking shoes

The present invention relates to a rear balance walking shoe having a sole in which double earth axes are formed on the sole at a rear side with respect to the middle of the sole, and the heel and the toe of the sole are elevated from respective double earth axes and perform see-saw motions at the double earth axes serving as application points. By wearing these shoes, the center of gravity of a wearer's body is inclined backward, resulting in reduction of obesity by activating muscles of the trunk. Still further, since a wearer feels comfortable even if the wearer wears the shoes for a long time and can reduce impact transferred to the wearer's feet, an exercise effect is enhanced.
