Developed by a pioneer in footwear-drying technology, this lightweight and portable unit works to dry any footwear overnight. If moisture gets into your boots or waders during a hard day of hunting, start the next day with fresh, dry feet. Just insert the power cells into damp footwear, plug them into any standard 120-volt household electrical outlet, and let footwear dry while you rest. It also eliminates odors caused by perspiration, bacteria and mildew, and extends the service life of your footwear compared to just letting boots, shoes and waders air dry.
