I have been trying to relearn to run the way our ancestors did it. Barefoot. I have never been a barefoot person. I even wear house shoes in the house. You almost never caught me without shoes. Here lies the problem, my feet are incredible soft and tender. I have been running on the track at the "Y" for a few weeks without much problem. I got a few blisters on one of these runs, but it wasn't too bad. Today I went to the "Y", but they just resurfaced the gym floor, so the fumes were soooo bad that I decided to run bare foot on the treadmill. HUGH MISTAKE. I got 3 huge blisters after only 11 minutes. Oh well. I have to go doctor my feet now.
