When wet weather conditions suddenly become icy, you'll love that the Korkers Men's StormJack Boot has the OmniTrax 3. 0 interchangeable sole system. This modern design adapts your traction to meet changing conditions, from the durable SnowTrac Winter Rubber Lug sole to the carbide studded IceTrac Studded Rubber Lug. These soles change so easily that you don't have to take your boot off, which means you have full versatility from the lodge to the trails. As you brave ice or packed snow, the sole effortlessly grips each surface while the waterproof leather and webbing upper keeps your feet dry. And with the addition of the 3M Thinsulate insulation, your feet stay toasty down to 20 degrees Fahrenheit, yet they won't overheat when you step inside.
