I have, along with What I Talk About When I Talk About Running. It can be an inspiration to start running or start running longer distances. But beware of the pseudo scientific narrative, don’t take it too seriously :)
Yeah, I read it when I was going through my barefoot phase. It's a good story overall but I am far less convinced of the barefoot movement these days than I was ten or so years a when I read it.
I started running barefoot recently. I have a hip injury that seems to flare up badly when I run with shoes. Running without shoes has me running slower and in turn putting less stress on my hip. I'm not sure if it's a good idea long term but at least in the short term, it helps me get back to running.
