Only because it's an open toe shoe is the tightness not too much of a problem. Most of my shoes are size 14...these are 15 and are the smallest fitting shoes I have. But they are so darn cute! And these are not "order and wear somewhere fresh out of the box"...the sole has NO grip, so you have to let them get some concrete action. I turned a corner and nearly did a full split. All in all, they should definitely label this size "15" as a 13.5, but the open toe makes it usable...maybe that was part of their thinking?????
