Like most who have posted, these mocs do run small and are narrow. I sized up a half size, only because I have a small narrowish foot to begin with. If you dont I'd reccomend trying on a whole size bigger, maybe more. They do loosen up with wear, so keep that in mind also. They are super cute , and I'm glad I took the chance and bought them. Their also comfortable. I havent had any negative experiences.
I really love these moccasins- very old school. I think I had a pair when I was a kid in the 80's :) I will say, however, that all the reviews stated that these shoes ran large. I did not find that. I wear a 7.5 or an 8 depending on the brand/style. I originally bought the 7.5's because of everyone's reviews and ended up returning them for 8s. They are comfortable, however, if you find that shoes in the style of boat shoes or sperry's sometimes cause you issues around the part of your foot where the toe comes across the top of your foot (I find that all boat shoes or bluchers or moccasins cut me across that part of my foot and tend to rub)- you will find that these have a similar cut and might be uncomfortable. I don't have a particularly wide foot, but find that to be a source of irritation. Otherwise these are soft and have a great sole.
