The Boot Dry is a safe, silent, simple, overnight way to dry footwear! Using thermal convection - naturally rising warm air - it removes dampness, perspiration and odor from all types of shoes or boots. Using minimal wattage, the Boot Dry is a cost- effective and economically friendly tool for daily use. Because the Boot Dry dries slowly with mild heat, thereâs no fear of shrinkage or stiffness and no need to remove shoes or boots promptly. In fact, it can even be used as a storage device for regularly worn footwear. The Boot Dry is quite simple - no moving parts, no noise, just plug it in and youâre good to go! Whether you work or play outdoors, you deserve to start each day with dry, comfortable footwear. The Boot Dry carries a 30 year warranty against defective materials or workmanship.
