The Abisko is a sturdy winter boot that keeps you warm for hours on end, even while outdoors during the coldest of winter days. Thanks to their unique design that incorporates a dual 7 mm neoprene and fleece inner lining, the Abisko is our warmest boot. 2 mm mesh ventilation ducts also help provide additional insulation while also transporting moisture away from the skin. The removable insole is made from a high-quality wool blend that is ideal for keeping warm, plus the shaft of the shoe is foldable to provide increased flexibility and rapid ventilation. The Abisko is also a highly stable boot with a good deal of torsion, a perfect pairing for its durable sole that has previously received accolades and awards for its exceptional comfort. With a double layer of reinforcement in the toe and heel, the Abisko is ready for even the toughest of environments and weather conditions — whether you’re taking long walks in the wilderness or ice fishing for hours, the Abisko has you covered and protected.
