I'd really like to know this as well. I've always had the same problem. I know my grandpa had A width feet, and he used to have shoes custom made. But aside from a few leather artisans who do very artsy, but rustic boots, I wouldn't know where to get those.
If you are interested in those types of shoes, though, Google "Bald Mountain Moccasins" and "Windwalker Moccasins". Gorgeous, made to a mold of your foot, and rather pricey. (Which is the only reason I don't have any.

I know Italian shoes tend to run narrow, as well, but I don't think they are probably
that narrow.
