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.
