These are great in theory - I liked that could be for rain or snow or with or without the liner - and we did get a few good months out of them. It does say 'cold weather' boot, but beware if you plan to use them for summer rain, or if you store your winter clothes in an unconditioned space. I don't know for sure but heat is the only reason I can guess that they are now deformed and useless. The ankles kind of collapsed in on themselves.
