There's a pair of Brian Atwoods on sale, but unfortunately, they're only available in size 38/8. Normally, I wear a 7 to 7.5 in Prada shoes, and a 7.5 to 8 in everything else. I usually buy my shoes in size 37.5 or 7.5 while shopping online, just to be safe. Can anyone tell me if Brian Atwood shoes run small or large? Would I be ok ordering a 1/2 size up from my usual size?
