  • Patent number: 5727335
    Abstract: Footware is made such that a thickness of a heel region from a sole upper surface to the ground is thinner at a backward portion than at a forward portion, whereby a line connecting a position on a lower surface of the sole under the head of the second metatarsus to a front end on a lower surface of the heel region of the sole is lifted at an angle with a horizontal line connecting a grounded rear end on the lower surface of the heel region to a front end thereof in a state where a weight is loaded to the human heel, and the backward portion of the heel region comprises an impact absorbing mechanism, whereby a level of the human heel which is in contact with a foot is depressed when loaded. Thus, the footwear protects a knee joint of a patient suffering from the osteoarthritis of the knee and enables them to easily walk.
