Ordered a size up (11) and still too tight for my true size 10, slightly wide foot. But these are great shoes. I considered stretching them out and only wearing them on non-walking days, but ended up sending them back because they were too uncomfortable. I have never worn a size 11 shoe in my life but if they would make these shoes true to size or even go up a size I would try on 2 sizes up and a size 12 just to have these lovely moccasins! Damn.
