I usually wear size 9. It seems I wear size 10 in Acorn (& 9.5 in Jambu, if that's useful to you). The 9 was far too small, the 10 fit pretty well.<br />The particular pair I received had a couple smudges on the shoe. I would've sent them back just for that, but in addition: I just ordered a few Acorn shoes. All have a strange fit: while the arch support on the inside of the foot (you know, where your arch is) is decent enough, the support on the outside side of the foot is more prominent, and there is a bit of a canyon under your foot, between these two. I do not understand it, I do not like it.<br />This pair is also a little more western than I tend to like, but I'm very sensitively opposed to slightly western-looking things.
