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.

A shoe for use by a person having a foot malady located in at least one site of the foot of the person where a pressure in excess of a critical threshold pressure has a detrimental effect on the malady, the shoe comprising: a shoe body to substantially enclose the foot of the person, said shoe body defining an interior surface to contact the foot, said interior surface provided with a relieved region in the at least one site to reduce pressure directed against the foot at said site; a force sensing resistor unit positioned beneath each said relieved region; a power source; a switch circuit connecting said force sensing resistor unit and said power source, said switch circuit detecting current flow through said force sensing resistor unit as a function of the pressure applied to said force sensing resistor unit, and providing an instantaneous output signal when the pressure exceeds the critical threshold; and an indicator means connected to said switch circuit to receive said instantaneous output signal to provide a signal to the person when the pressure in excess of the critical threshold is applied to said force sensing resistor unit at the location where the pressure is detrimental to the malady.
