Abstract
Abstract A SELF-CONTAINED HEAT GENERATING AND RADIATING FOOT WARMER FOR USE IN A SHOE OR BOOT WHICH HAS A RELATIVELY THICK OUTSOLE. AN UPPER ENCLOSED SURFACE OF THE SOLE IS FORMED WITH AN UPWARDLY OPENING CAVITY PROVIDING A RECEIVING POCKET FOR SAID FOOT WARMER. THE FOOT WARMER COMPRISES A CONTAINER WITH A PERFORATED CAP SIMILAR TO A CIGARETTE LIGHTER AND WHICH IS ADAPTED TO CONTAIN ABSORBENT COTTON OR EQUIVALENT FILLER MEDIA SATURATED WITH REGULAR IGNITIBLE LIGHTER FLUID. THE WARMER IS FITTED INTO AND REMOVABLE FROM THE POCKET. A TRIVET-TYPE GUARD IS LOCATED IN THE POCKET AND HAS CORNER LEGS FITTING INTO THE POCKET AND A PERFORATED PLATE PORTION WHICH OVERLIES THE FOOT WARMER. IT FUNCTIONS TO DISTRIBUTIVELY TRANSFER THE WEIGHT OF THE WEARER''S FOOT DIRECTLY TO THE BOTTOM OF THE POCKET AND PREVENTS THE FOOT WARMER FROM BEING CRUSHED.
