Abstract

A shoe to be worn by diabetic persons, or persons afflicted with various types of foot maladies, where excess pressure exerted upon a portion of the foot tends to give rise to ulceration. The shoe body is fabricated to have relieved areas in the inner surface that contacts the foot at locations where the excess pressure is thought to possibly occur. Mounted within each relieved area is a force sensing resistor unit that is connected to a switching circuit. When the switching circuit senses a pressure against the force sensing resistor of a value corresponding to a set threshold, the switching circuit causes the energization of an alarm unit to warn the wearer of the existence of this threshold pressure. At this point in time, the wearer can remove the shoe to prevent the damage to the foot. Provision can be made to adjust the critical threshold pressure at which the alarm is given.
