I am noticing the opposite. My daughter wears a 9.5, and her 8/9 Crocs are starting to get a little small, especially when she wears them with socks. She can't wear them with the strap around her heel anymore, she's been wearing them clog style. I was hoping she'd be able to wear them to Disney in December (they are the Mickey ones), but I may have to buy a new pair before then.
