Thanks for the replies! I think the one thing I need to do is go up a 1/2 size. I wear smart wool socks, I just can't do the toe socks it bothers me. I noticed that I have stubbed my toes, but also could it be jamming my toes at the front of the shoe when I go down a steep hill? I really want to solve this problem before my next ultra, which I'm in the planning stages for right now.
