Don't Go Through Winter With Cold Feet. ThermoFeet Keeps Your Footwear
20 Degrees Warmer!
With technology derived from the space program, ThermoFeet inserts use 99% pure aluminum applied to 2 sides of a polyolefin film. The result is 98% efficient reflection of body heat when placed under the insole or orthotic in shoes or boots. Although ThermoFeet have a series of pores to facilitate normal vapor transfer, they are not intended for direct contact with the foot.
Wear ThermoFeet Heat Insulating Insoles year round -- they also keep your feet cooler in the summer! Only 1.4 mil thin, ThermoFeet will not affect shoe fit. ThermoFeet inserts trim to fit sizes 3 to 15. 30 day guarantee.
