ABSTRACT:
Apparatus for blowing air into footwear for warming and/or drying the footwear. The apparatus has a seal for sealing an open or ankle portion of the footwear, and a duct assembly having intake and exhaust ports, and a discharge tube. The seal encircles the discharge tube and has a range of effective diameters to accommodate open portions of footwear of different sizes. The discharge tube is telescopically extensible and retractable of the seal to accommodate footwear of different heights and to retract within the seal for storage. A fan, communicating with the duct assembly and a heating element, draws air into the intake duct and discharges it through the discharge tube into the shoe. The apparatus can be used to warm and/or dry footwear ranging from high stiff ski boots to low soft running shoes, and accommodates a wide range of sizes of such footwear.
