Harvard undergraduates, William Werbel ’08 and Adam Daoud ‘09, both of The Nature paper arose out of the senior honors theses of two Sports injury can help people run better for longer and feel better “Our hope is that an evolutionary medicine approach to running and Only investigate barefoot running but can provide insight into how toīetter prevent the repetitive-stress injuries that afflict a high In the future, he hopes, the kind of work done in this paper can not You have to transition slowly to build strength in your calf and foot “If you’ve been a heel-striker all your life, “Running barefoot or in minimal shoes is fun but uses different The padded heel cushions the force of the impact, making Modern running shoes are designed to make heel-striking easy andĬomfortable. Minimal shoe running is something to be eased into, warned Lieberman. Or moccasins with smaller heels and little cushioning.”įor modern humans who have grown up wearing shoes, barefoot or Runners were either barefoot or wore minimal footwear such as sandals Running for millions of years, but the modern running shoe was not But as heĪnd his co-authors write in Nature: “Humans have engaged in endurance “Our feet were made in part for running,” Lieberman said. Homo sapiens, by contrast, has evolved a strong, large arch that we use as a spring when running. For example, said Lieberman, our early Australopith ancestors had less-developed arches in their feet. The differences between shod and unshod running have evolutionary To a sudden stop when you land, and by having a more compliant, or This collision by decreasing the effective mass of the foot that comes “Barefoot runners point their toes more at landing, avoiding Researcher in applied mathematics and human evolutionary biology at Ground,” said co-author Madhusudhan Venkadesan, a postdoctoral It causes a large collisional force each time a foot lands on the “Heel-striking is painful when barefoot or in minimal shoes because Springy step toward the middle or front of the foot.

Those who had always run barefoot, those who had always worn shoes, and Moi University in Kenya looked at the running gaits of three groups: Lieberman and his colleagues at Harvard, the University of Glasgow, and Working with populations of runners in the United States and Kenya, And here’s a video interview with Daniel Lieberman, produced by Nature. Further, it mightīe less injurious than the way some people run in shoes.” Here are videos of runners with and without shoes, and other extensive information about the findings. All you need is a fewĬalluses to avoid roughing up the skin of the foot. Without the slightest discomfort and pain. “Most people today think barefoot running is dangerous and hurts,īut actually you can run barefoot on the world’s hardest surfaces Landing on the middle or front of the foot, barefoot runners haveĪlmost no impact collision, much less than most shod runners generate Lieberman, a professor in Harvard’s new department of human evolutionary biology and co-author of a paper appearing this week in the journal Nature. “People who don’t wear shoes when they run have an astonishingly different strike,”said Daniel E. Three times body weight, that shod heel-strikers repeatedly experience. To avoid hurtful and potentially damaging impacts, equivalent to two to The architecture of the foot and leg and some clever Newtonian physics Scientists have found that people who run barefoot, or in minimalįootwear, tend to avoid “heel-striking,” and instead land on the ball New Harvard research casts doubt on the old adage, “All you need to run is a pair of shoes.”
