I bought these shoes in preparation for a two week trip to Japan. I wear a Men's US Size 8, and Nike is pretty good about shoe sizing so I had no problems with the fit. The first day of wearing it, the shoes felt a little stiff and tight around the top of the foot, but after you break them in it becomes very comfortable. There's a slight angle to the shoe when you look at it from the top, so the design looks a little lopsided when you look straight down at your feet. But no need to worry, because from everyone else's point of view the shoes look dope!
