I've never written a shoe review about them fitting oddly because I always think that people who do have ordered the wrong size. This can't be true for this review. I've worn exclusively Clark's (and some Softwalk's) for the last 10 years. I ALWAYS wear 8.5N but not in the Lexi Bark.
The rear half of this shoe is too short if I put my arch over the arch support. My foot hangs off the rear of the shoe by ~half an inch. The footbed is not flat. It slopes up around the edges. My foot rests partially on the raised part. The fit looks bad and feels bad.
The shoe is VERY narrow. That's OK for me in the front part of the shoe but in the rear  part, even when my foot is centered, on the sides my foot rests on the raised edges of the footbed.
Also the footbed is not made of leather. It is made of some man-made material that looks and feels a little like coated cardboard. I'm used to shoes with a leather or a suede footbed. I'm not sure how this man-made material wears.
I tried 2 colors - brown and sand - and they have the same weird fit. I'm going to try some other Clark's sandals this year.
