Ok, I have a pair in size 8.5 and a pair in size 9, I don't know which to go with! My left foot is a bit bigger than my right foot. With the 8.5 it's def a more snug fit, hurts a bit on my ankle bone, which I think is normal and goes away with break in. I can go with a size 9 but I think they may be too big, also, i know feet get larger longer u walk in them and as you get older, so maybe the 8.5 is not a good choice for long run? Need some input please
