NY - I've been having the same issue. My toenail is now black and dead (but that i'm sure was poor boot fitting). Anyway, I tried the SuperFeet, Hots, they really helped. They helped to set my heel back in the boot, support my arch, and have warmers in them so they kept my feet warm. I was having to take my boots off after almost every run, just to get the feeling back in them, waiting for that pins and needles feeling just to make sure my feet are still going to get circulation and work....I need my feet...This is probably too simple of a fix, and the other suggestions are probably going to be more fruitful, but I've struggled with this all season, and the Superfeet HotPinks (damnit, don't make me say it
). they helped me out.
