From OpticsPlanet

Norfin Klondike 2 Boots Grey 10 16990-43. Thanks to the thick and warm insole and EVA (foam rubber) material these boots can be comfortably used at temperatures as low as -40 F. The boots weigh 30-40 percent less than their rubber or PVC counterparts. Heat Warning - Like many materials found in footwear EVA rubber parts can be damaged by exposure to concentrated heat. EVA shrinks faster compared to solid rubber soles and can cause sole separation. Keep your NORFIN boots removable insoles or liners away from heat sources like fireplace campfire wood stove radiator heater etc...
