Sole

The heating or insulating insole is the essential accessory to ensure foot comfort against the cold, just like socks, in hunting boots or hunting shoes. There are even heating insoles that will spread heat to the feet, which is very useful when standing in extreme cold. Some are rechargeable, others are equipped with a remote control. Thermal insoles can also be used for skiing. Brands like Verney Carron line or Terratherm, Thermo soles, Heat models will accompany you in your hunting game, no matter how cold it is. I'm also thinking of other accessories like boot dryers or boot pullers.
