I went TTS and the fit is terrific.
I wear my boots one half size larger than my shoes because I slip a half-sole orthotic into all boots . This also gives me plenty of toe room that I like.
e.g I wear 7.5D in Barrie LWB but 8D in Barrie LW shell boot, 8D in Plaza shoe and 8.5D in Plaza shell boot, etc.
So, without the orthotic this Aberdeen lasted boot would have been OK in size 8D. I am 8C on the Braddock, so yes this boot can be worn TTS as long as without orthotic..
Funny you mention vintage because I had a pair like this about 40 years ago as a teenager. I think they were from a saddlery in NYC.
