I have been looking for a pair of simple brown flats for a while now, and these fit my wants perfectly. I was nervous about the fit, as I have a wide toe box and a narrow heel so most shoes will slip off the heel or be too tight up front. I originally got the 9.5 (I am a 9.5/10 depending on the make) and could hardly force my foot into it, way too small. Exchanged it for the ten, and the shoes felt butter soft and completely comfortable right  out of the box. They may give me heel blisters for the first eek, but that is the nature of my feet, I think. They don't seem to slip at all, super comfortable for flats. My ONLY complaint is that they show a tiny amount of toe cleavage which I normally don't like, but I can get over that for the classy look and total comfort.
