Heating Insole
Heating Insole

When one walks, the whole weight of body applies force on the insole, and the pressure on the insole can make friction in the molecular frictional heat layer and produce heat. The heat can be gathered and be stored in the heat storage layer of the insole. When it is getting cold and the temperature of the users’ feet drops down below normal, the vent hole in the insulation layer will open, then the heat will flow to the feet.
