Check out Alden: in my (limited experience) they make higher quality shoes then AE does, and they have a few lasts in the EEE sizes. (i think the Barrie, Hamton, Aberdeen and one other last come in EEEs] BUT, the extra quality of Alden is offset by the difficulty in being able to find them in the wide sizes: almost no-one carries them. So you may be reduced to ordering (and then returning) shoes from the factory in the various lasts until you find the right fit. I add that even though AE often doesn't have the shape/material/color combination you wish, you can order it special for $100 extra. e.g. i just ordered up a 12EEE from them, in a different material than usually available for the shoe, AND I got to specify the sole (in this case I wanted a reverse welt, double sole that extends the sole edge). You can do this with any of their shoes. which is nice if you want something unique. They also let you do this and order a different size for each foot, I believe. Good luck.
