These heated insoles are a must-have for outside work in the winter. With a wireless remote and cordless battery, the insoles can be customized to fit any shoe size from women’s 4.5 to men’s 13. They provide continuous warmth for up to five hours. The wireless remote gives fingertip control between medium heat (100°F), high heat (111°F), or no heat, all while your feet remain comfortable through the use of a built-in thermostat. Because they are water resistant, the insoles function well in damp environments and work interchangeably with shoes or boots. ThermaCELL. www.thermacell.net
