I haven't read a book this groundbreaking (no pun intended) since Sex at Dawn. There's a reason there are so many glowing reviews of Born to Run. The luxury of modern life has weakened our feet. If you're tired of knee and foot problems, READ THIS BOOK. I'll stop my proselytizing now.

Born to Run alternates between chapters of the search for the Mexican Tarahumara Indians, info about top foot researchers and distance runners, and play by play accounts of several footraces. Injury free running requires joy and technique - it doesn't matter how much your shoes cost.
