Do you think I should stick with a size 12 for the Ballistic 4.3? I bought some and they seem to have a little wiggle room (not sure if it's to much for not). I wear a 12 in every other pair of Nikes like my running shoes which seem to fit better, so just wondering if I should stick with a 12. I also wore a 12 on my Nike Vapor V's a few years ago. I am afraid 11.5 might be to small but just not sure. Anyone else noticed anything?
