@christopher That’s pretty extreme! I dabbled in barefoot in 2003, but only was able to run 2-3 miles before my feet hurt. It was a really weird thing to do then, but now looks less crazy. That’s a shame about your back. Don’t underestimate walking. I’ve had back injuries that hopefully won’t stop me. After such a long hiatus from running, it occurred to me that I might lose the ability if I didn’t act now.
