I took the advice of the reviews and ordered up a half-size. It was probably a good choice. I've had them now for a month and they have stretched out a little, so I had to tighten the straps. I'm now on the last notch, so I can't tighten them more. It only forces the toes down further anyway. They are a comfortable shoe and I didn't get any blisters even thought I walked in them for a couple of miles during the first week. They are a cute shoe and I find them very nice for work or with jeans.
