I saw those on the Crocs site yesterday and think they are adorable! But I have a question - does that fuzzy lining come out for washing? We live in Florida and I just know that if I bought some for my 4-yr-old, his feet would sweat like crazy and they'd smell to high heaven in about a week. I mean, I'm sure they're not too practical for him, as our winter high temps are generally in the 50s-60s, but that's cold to us and I'd love for him to have some warm shoes he could wear instead of his sneakers.
