GO UP A SIZE! 3 stars because I love the look of these shoes and if they were true to size they might be perfect. I normally wear a size 9.5, sometimes 10, so I ordered a 40, since that is what I usually wear in European sizes (and the seller even states that size will work when you're ordering). Unfortunately, they are too small. The toebox is really tight. The material is stretchy and I thought that might help but after wearing them for a few hours, they were just too tight. Order a size larger than you may need and you'll end up with a really cute, comfy shoe.
