Travis,
As Nick said you have to size up. I am normally a size 10 so I went with a size 11 sock. For Winter use I would go up even another size for the use of a thicker sock underneath.
I normally used a pair of toe socks to keep my from toes apart and blister free.
They can be tight getting on and off rounding the ankle, I blew a seam taking them on or off cant remember which. I just sewed them up, did not retape them but they have seen alot of use so a new pair is in order. If I can find the material I might make myself a custom fitting pair solving the issues with rockies.
