Scientist Daniel Lieberman recently finished a study. He found that running barefoot seems to be better than running in shoes. People seem to be born to run barefoot. Lieberman studied people who grew up running barefoot. Some were raised in Kenya's Rift Valley. The area is known for its long-distance runners.
