Query: Warm and fuzzy

I purchased these as a gift for a friend. She had been complaining of chilly feet and says these socks have cured the problem! Very warm and very fuzzy. Just one possible problem: they tend to slip off very easily. Fine to wear around, but just be careful and don't plan on wearing these for any activities that require a lot of walking! Overall, they are exactly what I was looking for.
