ABSTRACT:
A strip of electrical resistance heating element is sandwiched between plastic foam insulative layers of an insole. Wires connect between the ends of the heating element and a battery pack. The wires are lead along the edge of the insole and exit the insole rearwardly of the nominal position for the user's ankle bone. The battery pack incorporates two hinged shell halves for completely enclosing a battery. A strap holds the two shells halves together and secures the battery pack over the calf area of the user's leg. A contact connects the negative terminal of the battery to one wire. The other wire is connected to a switch terminal. A switch blade is pivoted on the positive terminal electrical contact from the positive terminal of the battery. In the on position, the switch blade connects between the positive terminal of the battery and the electrical terminal for the other of the connecting wires.
