Thurman55 Last: 10EUS Men's Brannock: 10.5E
I measured a half size down from brannock and came out with a 10.5 bumped down to a 10 Length. For width i measured with a taylors tape and cross referenced Nicks width sheet. I landed pretty firmly on an E width. The classic heel height and arch of the 55 last combined with the frontal toe space of the Thurman last is a godsend, that keeps me coming back to Nicks. This last works well for my duck feet. ( Wide forefront, more narrow heel )
