These are my first pair of crocs, and I initially didn't like them that much. I usually wear a 10.5 but since they are only offered in full sizes I want with an 11. They shoe seemed clunky, didn't breath, and my feet seemed to float around too much. However, after two days of active wearing the bed of the shoes are starting to from to my foot making them much easier to walk around in and much more comfortable. They still don't breath as much as I would like, but then again I am wrapping my feet in a waterproof substance, what do you expect will happen.
I also hoped they would look less like crocs with the new sneaker like front. It does help, but you won't be able to get away with wearing these out without people knowing you are wearing crocs.
