I've been living in these Crocs since I received them in the mail three weeks ago. I'm a size 6 1/2 and the size 7 is perfect. I read up on the sizing, because this is my first pair of Crocs. The Baya Lined is supposed to have a roomy fit with a little space around your foot. It does exactly that. It's roomy, comfortable and warm! I've worn them with and without socks. They molded to my feet in about a week. The back strap keeps them on good, and I don't have to clench my foot to keep them from falling off. They may not be the most attractive shoe, but they're cute in their own way. When the weather gets warm again, I plan on getting a summer Crocs of some sort.
