Picked up these three pieces the other day at the Prince & Mercer shop in Soho. Mediums on the buttondowns, large on the Henley (sizing was a little different)
I love this stuff so far...
Hi!
from the back of the heel on the sole to the tip of the front on my 10.5 D sanford's, the measurement is a shade under 12 inches, and about 4 inches across the widest point of the sole
hope this helps!
