I bought these a few years ago for snow shoveling for 17,000 yen. I usually wear 24.0cm, but these are a bit small, so I wore them about twice and then stored them. I've only worn them on snow, so I think the soles are clean. The inside is lined with fur from the ankles up. I don't know what kind of fur it is, m(_ _)m Please understand that these have been stored at home before purchasing. Thank you for your purchase ^o^ If there are any days I can't ship, I'll write them in my profile, so please take a look.
