I wear a 10.5 and order on the basis that these shoes are a bit small, most likely because of the tapered toe. I am returning them but have already ordered a size up as I expect they will fit me (hopefully!). I really like the quality of the shoes although as I can see from some of the comments others were disappointed. Can't speak to comfort as I couldn't wear them to walk in. Note that the white outer edge of the floor is REALLY white and will most likely get dirty very quickly. Most shoes similar to this one are usually off-white, but this one is as white as it gets without really shining :)
