Winter can be unpredictable, but your footwear shouldn't be. That philosophy lead to the development of the Muck Arctic Ice Tall AGAT pull-on boot with Arctic Grip. These winter high-performance sport boots step up the warmth factor with 8mm neoprene inner boot layered with cozy fleece lining for ultimate warmth in extreme conditions. Completely waterproof, these 17-inch boots have a stretch-fit top-line binding keeps the boots snug to your legs to keep cold air out and warm air in. The new Vibram Arctic Grip All Terrain outsole with Vibram XS Trek Evo compound provides advanced traction on all terrains including wet ice, snow, mixed/loose surfaces and hard pack; superior grip no matter the season.
