The problem is my local AE store rarely has shell and the shoe banks Cambridge is in new York. I am in New Orleans. The MTO would be on the same last as the shoe banks Cambridge. I've heard shell fits slightly different and I want an MTO shell strand.
I may give the outlet store a call and tell them my situation and see what they say.
I don't think there is a problem with what you want to do. I've ordered and returned many, many shoes from/to Shoebank.
However, if you want an MTO, I suggest you work with Allison. I believe she will send you shoes to try-on to nail down your size with no shipping costs. They will hold a deposit until the shoes are returned. I don't think the outlets can do that.
