I'm a 9.5 in Desert Boots, 10 in Desert Trek Boots, 10d in White's Smokejumpers, 10 in Chuck Taylor's, 9.5 in OSB Trail Oxfords. In general,I'd say I'm a US 9.5-10D. What size do you think I am on the 2030 last? I'm totally obsessed with the cap toe version!
Also, maybe a bit of a dumb question but are the Service Boots more approprately worn with dress or boot socks? I'm guessing dress, but they seem wayyy more rugged then say Alden's.
