For anyone reading out there reading the advice above ('going a half size up for Barrie last boots' versus what one normally wears in Barrie last shoes) I just want to point out that I am an 11C on the Brannock, and D width Barries don't fit me particularly well to begin with. I usually buy Barrie last shoes in 10D - one full size down, instead of the recommended half size. It usually works. But not for boots - just too tight (length and width) - so I 'sized up' one half size to 10.5D, and that works great for me. I've got a 10.5C Barrie last boot on order, which I think will be my perfect Barrie size for boots and shoes going forward.
