Actually there are two gMTOs I'm trying to put together:
1.) Color 8 plaza captoe boot, all metal eyelets, flat 270 degree welt, black edge, double leather sole
2.) Black shell barrie Indy boot, metal eyelets + hooks, 360 split welt with antique edge, commando sole
Was the plaza you tried shell or other material? It depends on how you like your shoes to fit (snug or loose) but I would not expect/depend on stretch with wear, especially with shell. The cork footbed will settle after break in and your feet will drop a bit into the shoe, but usually that's not significant enough to alter the fit. In my experience suede and CXL will stretch with wear, some people will even size down to compensate, but shell will never stretch. So if you are ok with the outside toes touching, then 7E is fine, otherwise I'd size up to 7.5E.
Ohhhh nice! Missed that one. I'd be in on #2 if you're doing C width, and of course if Alden agrees.
