While the old adage said “all you need to run is a pair of shoes,” researchers have found (and reported in Nature magazine) that all you need is a pair of feet. In their study, the researchers found that, before the invention of shoes, humans ran differently . . . and better.
It turns out that humans avoided heel strikes when running barefoot — and thereby avoided many of the injuries that plague modern runners. They would instead land on the ball of the foot or the middle of the foot. The researchers, including Daniel E. Lieberman, professor of human evolutionary biology at Harvard University, found that this technique uses Newtonian physics to avoid damaging impacts.
