i think i could of went with a 10, but the 10.5's have broken in really nicely. either way, they will stretch a bit if they're a little small, but if it's too tight you risk damaging the stitching and sort of "squeezing" the leather. i would go with the size you feel confident with, i wouldnt try to size down because i don't like the idea of letting the horween leather stretch out. like i said before, i wear 10.5 redwing boots, and i went with a 10.5 oak streets and they were lovely right out of the box.
they get more comfortable everyday.
here are some more photos i snapped today:
