If I'm at home or work I don't put anything on the blisters. I pop them with whatever sharp object is handy, and keep on with what I'm doing. They are usually sore for a couple of days after the skin peels but never a big problem. I get them on my hands any time I do any real work - amazing how a mouse and keyboard don't build up callouses. The only time I get blisters on my feet is when I run barefoot on the treadmill. <Insert wisecrack about my intellect>

It may sound dumb, but I think of it as an experiment. If I was in a non-standard situation (in the woods or facing a long walk) I would take more appropriate measures. And I always have moleskin, tape, bandages, and neosporin in my kit.
