A Foot Warmer Mat is designed to keep one's feet comfortable-even through shoes or boots-in cold and/or damp indoor areas (e.g., shop, standing workstation, garage). It can also help minimize pain caused by poor circulation, arthritis, plantar fasciitis, neuropathy, and restless leg syndrome. Reportedly generating as much as 140 degrees of direct or radiant heat, this plug-in product requires approximately 50 to 150 watts of power (depending on make/model). Most mats are available in two sizes (about 24- x 14-inch and 36- x 16-inch), have a soft-cushioned fabric finish, feature a built-in thermal protector to prevent overheating, and are double-insulated to reduce heat loss to the floor.
