Need extreme winter boots? The Snowline is your best bet. The fact that this boot was field tested in the tundra of Siberia is proof enough that this winter-ready boot can stand up to the harshest weather conditions. Choose from either 8.5mm or 12mm of the lightest foam insulation you’ve ever experienced in a hunting boot. Lined with half a millimeter of moisture-wicking fleece, the interior of the boot traps warmth in while keeping sweat away. This is truly a boot that Old Man Winter won’t be able to penetrate.
