Insulating
Do the natural thing and add an additional layer of insulation for winter. The BootGlove™ has been tested* to hold in body heat adding up to +53 degrees to the shell temperature of your boot for toasty toes. ThermoFeet™ reduces loss of heat by reflecting your feet's heat back, resulting in an added 10 to 20 degrees F to the temperature of your footwear. By using the BootGlove™ and ThermoFeet™ heat reflectors as a layer the same as you would with the rest of the body you will be conserving heat loss where it is important, your feet.
