I normally wear an 11 wide. I ordered the 11.5-12 and they are perfect. They are stamped 42 on the bottom which is what I wear in European sizing. These boots are gorgeous! Incredibly good quality, soft, supple leather. I got them in the color 'Lead', which is a deep smoky gray that fades into black on the tips, and accented a deep dark brown. It's perfect for someone who wants a soft, almost black. Usually with my wide feet I have to use shoe stretchers on boots to widen them and lift the instep, but these fit perfectly from day one. They are my new favorites and I will get years and years of wear out of them for sure! Worth every penny.
