This is what happens when one runs out in the snow with bare feet for about 10 minutes at -25C. I was lucky. I damaged the living tissue just enough to blister off the calluses on my feet. Had I frozen them worse, they would have turned black and purple and have been really ugly. All in all it was a pretty mild Dope-Slap.
Why was I out in the snow with bare feet? Actually, I do it quite often when I think I will only be out for a moment and I am too lazy to put my boots on. This time my dog got into a nasty dog fight and I was in too much of a hurry to break it up to put my boots on. It also took longer to separate them than I was expecting.
