The Gamvik winter boots look good while defeating the snow. They have the classic duck boot silhouette with a weather-protective, vulcanized rubber lower and a water-repellent, seam-sealed upper. We enhanced the lower with our HH FreezeBlock aluminum shield technology to keep your feet dry and warm. The sole has our best traction technology to help prevent slippage on frozen surfaces. On the interior, the boot has a warm Primaloft® insulated sock with faux-shearling trim. The Gamvik winter boots have a 30-40°C/-22/-40°F thermal rating.
