J. Crew captoe boot on a last OTHER than Barrie?

[electronicsjunkie]

I bought a pair of the J. Crew captoe boots and exchanged them due to a defect. When I got the new ones home, it occurred to me that the soles look considerably narrower than those of my Barrie LWBs (and I think, narrower than the boots I turned in). J. Crew's website still says the boots are on the Barrie last. But is it possible that they are also making them on a different, narrower last? I'm not sure if the numbers on the inside of the boot would answer the question - I tried googling them and nothing of interest came back.
