I wore these immediately.  Comfortable fit and if anything, they may be smaller than the size I normally feel comfortable wearing, I hope they wear in and are not as tight.  This does vary from maker to maker and model to model, I've read.  The straps, in the origional position were a little tight and I loosened both shoes top strap and back strap, but not much the finish look of this shoe is good and though I have not worn them long the feel good and look better.  I like em.
