While the beginning drags, I did enjoy the book, particularly the latter third discussing why our species survived when the stronger Neanderthals did not and why we, humans, are literally built to run.
I have been semi-interested in the "barefoot" running concepts of the Vibrams and NikeFree for a while - you never hear of Kenyan runners who grew up barefoot getting foot injuries! - and might need to try them out now. Heck, the over the counter insoles I use are harder than the insoles that came with my shoes, so that's sort of like getting closer to barefoot right? (Actually it might be totally the wrong direction...I don't claim to be an expert on foot motion!)
Regardless, this book has convinced me and my ongoing arch pain - which I am told is a weekend warrior issue and my feet are fine - that I should more seriously consider strengthening the muscles and tendons I was meant to run on rather than trying to find shoes to fix me better.
