The Kamik Alborg is a classic winter boot for men that not only keeps your feet warm, but also dry. Sealed seams: This technology makes the boots waterproof and snowproof without increasing the weight. By processing the leather and nylon and covering the seams with waterproof tape and sealant, Kamik makes your feet feel like they're in a cocoon - safe and dry. Zylex: Kamik's patented Zylex technology is the modern innovation for good heat-moisture management. The revolutionary three-layer design transports sweat away from the feet while keeping body heat inside and the cold outside. With additional reinforced seams and heel protection, durability is guaranteed. The inner shoe is easily removable for washing and drying.
