I have ordered the shoes from this exact company a year ago, and they were loose on me in size 37 (US 6). I ordered the same size from the same company and they are too narrow in the toe area and rub in the back. I'm contemplating ordering a size up, because the shoes are very cute, but hesitant because it seems that the back side slopes up just a little too much and I may have the same problem with the larger size.
