These heated slippers use a Thermal Phase Change material that was developed for NASA astronauts. What the slippers do is store your body heat in a microcapsule-insulated polyester lining and then release it back when your feet start to get cold. The result is that your feet stay at a constant, comfortable temperature.

The slippers feature a genuine Adirondack deer-suede upper trimmed with piping and faux fur. The outsole is made of a flexible thermoplastic rubber and has a skid-resistant tread.
