J Crew normally doesn't order Barrie size 12.5. But, I encourage those of us that wear that size to call their customer service number and ask them to start ordering our size. The last person I spoke with was sympathetic and said she would pass that on to the buyers. Not sure it will make a difference, but if more people call, it might help.
That's what I feared. I was doubtful that J Crew stocked any Alden in 12.5 or 13 but thought I would ask. I haven't heard anything from them yet regarding the nationwide search, but I'll be sure to post here as soon as I do.
