They are virtually the same. The Brooks have some rubber on the outsoles and Poron insoles; but construction, lasts, and design otherwise are identical.
There was a comment a while back that Brooks had not initially chosen to participate in the AE recrafting program. Not sure what the status is. Probably need to ask AE about that when you inquire about the shoes.[/quote]
Just got word from the rep that BB versions are recraftable also.
