Yes, at least to start.Beware the widths. Green's philosophy is that their shoes should fit snugly in width- like a slipper. Snugger than most Americans are used to. So no translation in widths is necessary. That is of course different than (all?) other British makers. For example, a C&J E equals an American D.Proof of this you say? The sizing written inside the shoes shows two lengths but only one width.
