i've bought custom shoes in the past and without fail what happened is what i imaged would happen. they didn't fit.

and unfortunately, there's no way anybody can predict what a shoe is going to fit like without trying it on first. and understandably, the custom shoemakers are few and far between that will make a shoe for you, let you try it on, and THEN let you decide whether or not you want to pay for it. but if you can find one, i'd take him up on the offer.
