I had a pair of waterproof, thinsulate Kamik ankle boots. They were great for Canadian winters and classy enough you could wear them anywhere, wore them for about two years. But then during COVID I left them in storage and when I took them out two years later the soles disintegrated :/. Not the fault of Kamik, I learned that the rubber needs to be used or it falls apart. I think if it weren't for the storage they would have lasted a while, they were still going strong and winter is harsh up there.
