I just got these in a 10.5 and with socks it worked out perfect. i normally wear a 10.5 so just order your size. They are a little big. between the liner and the exterior shell they are bulky. i had to extend my ratchets on my flux tt's to fit around the boot. but it doesnt toe drag on a regular width board. just make sure you get the tounge on the liner strait before you snug it down or it will rub. It's a great boot. Ive taken some slams on some ice from about 15 feet up and my feet didnt get that shuttery feeling. Solid boots for sure. pretty stiff but it should be.
