I bought these 3-4 years ago and used them once. I've been storing them in case of snow, but I haven't had a chance to use them in recent years, so I'm putting them up for sale. The following is a description from the Montbell website: These are lightweight winter boots with an upper made of a supple material that prevents snow from sticking, and the upper can be folded down to be used as short boots. They combine lightweight construction with excellent heat retention, using Thinsulate™, which provides high insulation even when thin, and E.V.A. foam in the bottom, which has excellent insulation properties and maintains warmth. Specifications [Material] Upper: Polyester, natural leather, E.V.A. foam Lining: Polyester fleece Insulation: Thinsulate™ Outsole: Ice Gripper [Color] Navy (NV) [Size] 25.0 (25.0cm), (Unisex) [Features] Ice Gripper / Sole replacement not possible Gender...Unisex There is a barely noticeable name written on the inner tag. There are minor scratches due to the long storage period, but no major damage. The inner boa is clean. I usually wear 25cm shoes and wore these.
