ABSTRACT:
An apparatus melts snow off a person's footwear without the need for the wearer to take off the footwear. In particular, the apparatus is for melting ice and snow off the footwear, for example shoes, boots or sneakers, of the wearer by a directed and accurately disseminated heat flow. The heat flow is directed in a manner which facilitates the removal, deposition and collection of melting snow and ice from shoes of a wearer at a desired location, e.g., in a threshold or landing, adjacent an entry/exit door of a residence or commercial building before such snow and ice and any contaminant therein can be tracked into the building.
