I wear a size 13, sometimes less. The 13 was too tight—no toe room. Plus, the way it's manufactured, the toe quickly tapers (mine were rubbing against the top of the shoe in a way that would probably put a hole through the material before too long). I returned mine. For ~$23 it seems like an OK shoe, but looking at the way it was manufactured I didn't see it lasting much longer than several months (I could be wrong). The material the upper part of the shoe is made of, although thin, is very soft and quite comfortable. Shoes were light—seems like a comfortable, nice looking option for casual wear (if you order a size up).
