The MaxxDrySD is a safe, silent, simple, overnight way to dry footwear! Using thermal convection – naturally rising warm air – the MaxxDrySD removes dampness, perspiration, and odor from all types of shoes or boots. Warm air gradually rises to dry rain soaked shoes or hard to dry boots harmlessly. Overnight! Using minimal watts, the MaxxDrySD is a cost- effective & economically friendly tool for daily use to dry or warm footwear. Because the MaxxDrySD slowly dries there’s no fear of shrinkage or stiffness and no need to remove shoes or boots promptly. You can even safely store shoes or boots right on the unit until ready to use again. The MaxxDrySD “Silent Dry” is quite simple – just plug it in! Whether you work outdoors or encounter the soccer nation, we believe your family deserves to start each day with dry, comfortable footwear. And a dry comfortable shoe is a healthy choice. The MaxxDrySD carries a 30 year warranty against defective materials or workmanship.
