Physical Therapy and the Modern Man
Dan Conway

I had a similar experience after reading Born to Run. Bought some flat soled feather-light nikes, increased my running, and ended up with sore feet and back problems. My chiropractor questioned my sanity and insisted I stop running. I didn’t, but I got a new pair of running shoes with lots of cushion, and cut back a little. I skipped the PT part, but am rethinking this after learning about your experience.
