I don't think it would work. I am about a 8.25D on the Brannock and went with a 7.5 in my 2030 Boondockers. They are pretty snug in the toes, both length and width but seemed to still be the best fit (I do wear thicker socks with them). The 7 was way too tight (could maybe wear with dress socks exclusively) and the 8 felt like after it broke in it would be too big.
Actually wearing them today.
Looks awesome! Don't see many plain toes around though. Would the brannock size be the usual sneaker size? I got measured by one at red wings but i forgot to take note of my brannock size..
Sorry I'm an engineering student
