Question for those of you who have American Duchess shoes

How do you find they fit? I'm thinking of the new 18th century Dunsmores at the moment, but I could probably also use the buttoned boots eventually. A pair may be in my future and want to know what size I should be looking at. (I want to do my research because it's like $20 to ship to Canada and I don't want to have to deal with figuring out returns.) I tend to have wide, flat feet. I'm usually a 6.5, sometimes a 7. I measured my feet and according to the size chart I'm probably better off with a 7.5. But what have you guys noticed about the fit on American Duchess shoes? To they tend to be narrow? What do you think about potentially stuffing the toes or heel a bit?

Thanks for the input!
