Bendable Carbon-Fiber Forefoot & Sole Matrix
Instead of stiff metal wires that feel lumpy underfoot, Wattoes™ embeds an ultra-thin sheet of flexible carbon-fiber heating filaments directly beneath the forefoot and arch cushioning layer. The matrix flexes naturally with your stride while radiating smooth, even warmth upward into your toes and soles within minutes of activation—taking the bite out of unheated basement offices, drafty living rooms, and cold morning tiles. Each slipper houses its own pocket-sized USB battery pack inside a discreet side zipper pouch, giving you complete freedom to walk from space to room.
