We've found the Peet Shoe Dryer to be the best on the market. Instead of drying with heat, as many dryers do, the Peet Dryer utilizes air circulating through your boots at a low temperature. No moving parts, you can run the dryer 24 hours a day for about a penny. Damp shoes dry in about an hour; soaked shoes will dry overnight. You can start each day with warm, pliable, comfortable footwear. Boots and shoes last up to 50% longer. Fungus and odors are stopped. The Peet carries a 5-year warranty.
