I really like the style of these shoes, and they seem really practical.  Sadly, they run quite small.  I usually wear a 10.5, so I ordered that initially.  They were a little too small, so I ordered an 11.  Still too small.  11.5 fits well, but I have size 11 shoes that are looser.  I wish I could've found these in a store so i could've tried them on rather than paying another fifteen bucks for return shipping. Oh well.  If you order these, I'd recommend going up at least a half size.
