Do they ? I dont think so.. I called up Carmina the other day and asked them to help me with all the shoes they have in Simpson last in burgundy. She never mentioned anything about two different simpson lasts. Anyways AFAIK simpson is the narrowest last. The next I think comes the RAIN or ALCUDIA, almost similar to simpson. But definitely not as similar to be confused. There must be some kind of a misunderstanding.
