Not sure that there is a place that won't get annoyed at you trying on over a dozen pairs of shoes to figure out your size in order to buy shoes from other retailers. I wouldn't be surprised if Ralph at Alden Madison has thrown someone out of the store for trying to do such a thing.
You probably don't need to know your size in every last anyway. Chances are, you will only ever own shoes in 3 or 4 of them. You can go to J. Crew to determine Barrie and Tru Balance. They are likely to put up with it. Come back with those sizes as proxies and we can probably zero in on your sizes for other lasts. We could probably be pretty accurate with just your brannock measurement any notes about peculiarities of your foot (high arch, high instep, wide forefoot, narrow heel, ect).
Personally, I'm pretty much over Alden. I think its been over a year since I bought a pair. I have most of what interests me, there are very few new models being introduced, the prices are getting to be more than the shoes are worth [to me]. The only thing that is consistent about their QC is that it is consistently deteriorating. I have a pretty well rounded line-up at around 20 pairs of shoes. Anything additional is just excessive, however, I am still adding, albeit at a decreased rate.
Pick up some stock models in Color 8, Black, and non-cordovan leathers if any of them interest you. If you get lucky and grab a hard-to-get pair, that is just a bonus. This is basically my attempt to manage the expectations of someone who is new to Alden. Chances of you getting a ravello boot are almost non-existent. #4, basically impossible. If you are able to grab a LWB in an exotic color, that is something to be excited about.
Thanks for the info. Will hit up a J Crew and get the Barrie sized right.
I've come to terms with me not getting a #4 basically ever. I was curious what you think the chances are to get the captoe boots in Cigar. The #8 is pretty but the Cigar is just gorgeous. Thanks again for the info you guys have all been incredibly helpful.
