Winter waterproof shoes. I usually wear 28.5 to 29 cm, but they fit perfectly with thick socks. By the way, I have wide feet, and I think these are designed for wider feet. I usually wear La Sportiva and Scarpa EUR45 (around 29 cm) for my mountaineering boots. These are unused. I bought them after being told that the Vibram sole has been treated with sandpaper (black part) to make it less slippery. Thank you. The MERRELL winter boots "THERMO CROSS" are recommended for outdoor activities. They exhibit excellent waterproof breathability (M-Select DRY), insulation (M-Select WARM), and grip (Vibram ARCTIC GRIP A.T.) in cold regions with snowfall. Notably, the winter sole "Vibram Arctic Grip" uses a special rubber that maintains its hardness from 20 degrees to minus 20 degrees Celsius, boasting high grip on ice. Furthermore, the integrated tongue prevents the entry of dirt, pebbles, and water, providing excellent functionality. In addition, the midsole has been changed to FloatPro foam, achieving weight reduction. It is the perfect tool for safe and secure activities on icy roads and snow.
