I have wide feet in the front and narrow heels, and normally wear size 7 (or European 37) in all of my shoes. Occasionally I go up 1/2 size if the shoes are really narrow. For me, the Sedarabys run big. I wear 37 or 37.5 in Manolos, but I am a 36.5 in Sedaraby. Every sales associate who has helped me told me that this is common. I don't know why the Neiman website says they run small, because they definitely do not run small. I wouldn't even say that they are true to size.
