An extreme thermo boot for the most extreme conditions - the Icefighter was built to endure the cold and keep feet warm down to an incredible -40 °C. This high shaft thermo boot combines the high quality, lightweight and insulating polyurethane called Elastopan® with an ultra warm wool and polyester lining. Elastopan® is a 100 percent PVC-free and contains millions of tiny air bubbles and provides 2.5 times more insulation than normal PU boots, while being twice as durable. The sole is extra thick and gives great insulation and grip on ice and snow. These boots feature a Nordic cold climate last, which is wider, with more room in the toe area, since cramped feet could lead to frostbite. The Icefighter is great for snowmobiling, ice fishing, shoveling the driveway - any activity where you encounter the deepest snow and coldest temperatures.
