Columbia dark blue snow boots with excellent waterproof and thermal insulation. - Brand: Columbia - Color: Dark Blue - Material: Synthetic Fiber - Style: Snow Boots - Features: Waterproof, Thermal Insulation They are 25cm, but a bit large, and fit perfectly for me, as I usually wear 26cm sneakers. I only wore them for one season on my days off, and there are no noticeable stains. Thank you for looking.
