Is the lug sole on some of the other Fan models comfortable?
Yes, it is comfortable. Keep in mind, though, that it's just hard rubber stitched over a regular leather outsole. It provides traction, not cushioning. The shoes are about as comfortable as standard leather-soled shoes.
Also, would I be better off going up to an 11D or wider to a 10.5E?
The only way to know for sure is to try both sizes on. Keep in mind that 2210 is made on the Aberdeen last, while AF39 is made on the Plaza last. Different lasts, different fittings. FWIW, I've found Aberdeen to be a touch on the narrow side. Talk to Adam Knott at Alden of Carmel. He's very familiar with all of the lasts, and he'll probably be able to ask the right questions to make a sensible recommendation about the size. He'll also allow you to exchange the shoes for another size if needed, provided that you haven't done anything silly with the shoes.
Finally, thew Fan norwegians and loafers look more elegant than the standard models. Is this the case?
Well, they're certainly more unusual. The standard Alden shoe strives to be conservative and sensible, while the Fan shoe strives to be a touch more interesting. I think that Adam's use of whiskey, mahogany, and cigar shell cordovan instead of the standard Color 8 or black makes for more elegant shoes, as does his use of the Plaza last. Some of the models come off as being a bit clunky because of the extended welts, but overall, I think your statement is accurate. In particular, from the pictures, I would think that AF39 would be a more elegant shoe than 2210.
