The winter can be unpredictable, but your footwear shouldn't be. That is why we've developed the Arctic Ice Mid with Arctic Grip. These winter high-performance sport boots step up the warmth factor with 5mm neoprene inner boot layered with cozy fleece lining for ultimate warmth in extreme conditions. The stretch-fit top-line binding keeps the boots snug to your legs to keep cold air out and warm air in. The outsole features Vibram Arctic Grip with Icetrek, the new ground-breaking sole technology specifically engineered to perform in wet or dry ice conditions. Vibram Arctic Grip is the most advanced cold weather gripping system Vibram has ever created; now you can tread on the iciest of surfaces with confidence.
