I take an 81/2.  I was going to order an 8 since they weren't offered in half sizes but a little message popped up suggesting I buy a 9.  I did.  They fit like a glove, they're lightweight, stay on your feet when you walk, don't bind or rub anywhere, and they're a perfect height to bring me all the way up from 5'3" to a whopping 5'4" and 1/4.  haha. Please, Sketchers, NEVER discontinue these shoes.
