Jimmy, I read your post
Jimmy, I read your post about your blisters the other day and thought that's too bad, hope he gets through it OK. Well today, during my BFR transistion, I decided to walk on a bike path for about half a mile. Temp was about 80 and sunny. It's older asphalt, so its more grey than black. It didn't really feel that hot or uncomfortable, but when I got home sure enough I had developed some blisters, not as bad as Adam's though. I've walked this same path in the evening without a problem. I guess the foot's heat sensors are not as reliable as other parts of the body.
PS. Adam: How long did it take for you to resume running after those awful looking blisters?
