I just received these in the mail and walked around briefly. My feet said aaahhh when I put on these clogs. The sole is SO comfortable. My feet range from size 5-5.5, size 6 if it is a tennis shoes. These size 5, or 35.5 fit me fine. I would say it is true to size in both length and width. The nubuck is more of a grey than the blue-gray of the photo. It looks like it might easily show marks, but that is the price you pay for nubuck. Unfortunately, sigh, I will have to return them. The same problem I have with any shoe that come up my heel in the back is true of these. It slips up and down, and not because the shoe is too large. It would rapidly wear a blister on my foot. Perhaps, and only perhaps, if it came up higher like in a regular shoe, it wouldn't do that. However, as a slip on, I expect it would do the same thing. It is a problem with my foot, not the shoe. That is why I usually only buy backless shoes.
