ThermoFeet™ eliminates a primary source of heat loss through the bottom of your footwear.

Tested to 10 - 20 Degrees Warmer. *ThermoFeet™ technology installs to the underside of your insoles and utilizes 99% pure aluminum to achieve a 98% efficient reflection of body heat.

ThermoFeet™ are the same thickness as a dollar bill (1.4 mils.) and will not adversely affect the fit of the footwear. ThermoFeet™ have a series of pores to facilitate normal vapor transfer, but are not intended for direct contact with the foot. ThermoFeet™ are normally placed on the bottom of the insole or orthotic or to the top of the shoe sole when the insole or inner boot has been removed.
