Yeah i could definitely step down in size from the Raichle's. Just got a custom footbed a couple weeks ago and it works like a charm. I think the conventional wisdom that a footbed will shrink your MP may be true. I measure 26.0 on the dot with bare feet. Havent tried with the footbed yet. I have a good amount of space in the toe box on my raichles, but i don't buckle them too tight, maybe about 2/3rds of the way. I would like to go tighter and would like to feel the UPZ's, but i don't want to go psycho on my feet.
Anybody that can answer the foot size MP to boot size MP would be a savior.
