BTW, kudos to you for going an hour barefoot in the snow. I ran in snow yesterday at 21F (-6 C) and got frost nip after about two miles (3 kilometers). I thought I was within my tolerances but I guess not.You don't have to tell me. I've busted a knuckle more than once on a cold morning working on an engine or some such thing. The pain is certainly magnified over the same injury in the summer.
