"I ordered up after reading many reviews on another site--I'm a 7.5 and ordered a 39. Yikes. The 39s are a bit too long, but just make the width requirement--there is no way I could have worked a smaller size. The t-strap means I won't step out of the shoes anyway. The thick heel base makes the shoes very comfortable. Might buy another pair in another color--I bought the yellow and love them."
