I wear 8.5-9.0 medium (mostly prefer 9 in textured and athletic shoes and boots) and I've ordered 10 which fit perfectly and I can them wear with or without socks. I would definitely recommend ordering full size shoes to start with as you will likely need more room considering these are dance shoes. They appear to be of medium width with a slight tendency to be the narrower side of medium size. A person with a very narrow foot may only want to order a 1/2 size instead of a full size. Aside from the sizing issue, the leather is very soft, pliable and the shoe conforms to my foot very well, does not catch, pinch or chafe and there is no need to break them in. This shoe fits like a soft leather glove. Very good! For additional reference, insole size 10 is exactly 10 inches and my foot size (toe to heel) is 9 7/8 inches. I believe that size 10 corresponds to a size of 40 euros. hope that helps
