Abstract: A shoe includes a sole including front and rear compartments; a warming device in the front compartment; a main battery and circuit board in the rear compartment and enclosed by a first insulation member; a switch on a heel cap of the shoe; a display member on the heel cap a light emitting member on the heel cap; and an auxiliary battery enclosed by a second enclosure in the heel cap. The main battery and circuit board is electrically connected to the warming device, the push-button switch, the light emitting member, and the auxiliary battery respectively.

Abstract: A ventilated shoe includes an outsole; an insole including projections; and a space defined by the insole and the outsole and including resilient pillars in the instep and interconnected the insole and the outsole, a battery compartment, second compartments, motor-driven vibrating devices located in the second compartments, an exposed first switch, a heating element, an exposed second switch, and a circuit board with the first and second switches provided on its edge. Turning on the first switch will activate the vibrating devices to vibrate the projections to perform a first operation to massage the sole. Turning on the second switch will activate the heating element to perform a second operation to warm the foot.
