Mountaineering boots with Vibram soles for high grip. - Brand: Approach Shoes - Color: Yellow/Black - Sole Material: Vibram sole - Features: High grip and durability - Uses: Mountaineering, trekking I used these in the snowy mountains for about 3 years, but I didn't go to the mountains very often. The soles have no cracks, and they also have good heat retention. They are compatible with a wide range of crampons. Thank you for looking.
