Here is a kicker . . .
My foot size is 11.5
AE sized me in 11eee - which was much more comfortable because of the last. When I spoke to Paul last week, I mentioned that my 11.5 foot was more comfortable in a half size smaller, with a triple e.
I moved to Montana from Newport Beach (where the shopping was GREAT). Now the nearest Nordstroms is in Spokane, Washington - if I was to be fitted in-store by a professional.
Otherwise, AE recommended that I order online - and if it does not fit, they pay for return postage - back and forth, back and forth - which I think is okay if I lived in the North Pole. And because different styles may predict a completely different size - I think I will take along a notebook to Nordstroms and try on every style that strikes my fancy - so that when I return to Montana I can return to online buying with the correct fit.
I would call ahead and ask what styles they actually have. I made a 45 minute(one way) trip to the closest Nordstroms and they only had eight total styles and two of them were loafers. It was a very disappointing trip for me as they didn't have any of the orthotic line and Park Avenues would never fit me. Driving all the way to Spokane just to have a really limited selection to try on would be very disappointing. I've made the Spokane -> Great Falls trip a number of times and couldn't imagine doing it just to try on shoes.
