"Love these booties! I don't have the issue others had with the button coming undone. I only use the inside button & zipper; I've read on another review that the outside zipper/button is not meant to be used, just for looks. The only thing is that I have slightly wider feet so they're a little tight if I wear normal socks; I have to wear thin socks or tights with them. But I still love them! Get them!"
