I haven't read it. I'm pretty focussed in on the research papers, not so much on the semi-fictionalized stuff. Eventually I'd like to read it, if only because it's the first exposure so many people (who didn't run track in school, or who didn't run before the latest fad in shoes) have had to the concept of barefoot running.
When I get through the huge backlog of research stuff...

(I'm getting quite a kick out of all the papers from 1905-1910 about running barefoot. Truly there is nothing new under the sun!)
