The Men’s Arctic Pro Boot is designed for use in extreme winter conditions. These boots feature 2mm of thermal foam beneath the footbed and a fleece lining to keep feet warm in extreme cold. These boots also feature extra thick 8mm neoprene that adjusts to the contours of your feet, greatly increasing comfort and retaining natural body heat. A rugged outsole and EVA midsole provide more comfort and superb traction. A topline binding keeps snow and cold out.
