New research is casting doubt on the old adage, "All you need to run is a pair of shoes."
Scientists have found that those who run barefoot, or in minimal footwear, tend to avoid "heel-striking," and instead land on the ball of the foot or the middle of the foot. In so doing, these runners use the architecture of the foot and leg and some clever Newtonian physics to avoid hurtful and potentially damaging impacts, equivalent to two to three times body weight, that shod heel-strikers repeatedly experience.
"People who don't wear shoes when they run have an astonishingly different strike," says Daniel E. Lieberman, professor of human evolutionary biology at Harvard University and co-author of a paper appearing this week in the journal
Nature. "By landing on the middle or front of the foot, barefoot runners have almost no impact collision, much less than most shod runners generate when they heel-strike. Most people today think barefoot running is dangerous and hurts, but actually you can run barefoot on the world's hardest surfaces without the slightest discomfort and pain. All you need is a few calluses to avoid roughing up the skin of the foot. Further, it might be less injurious than the way some people run in shoes."
Comment: These contributions have mainly benefited large corporations and pharmaceuticals. If Gates really wanted to help the masses and prevent diseases and deaths all he needed to do is set up a system that distributes the surplus food stocks to the millions of starving people and use his influence to prevent the US war machine from implementing it's "War on Terror" which has killed untold millions - not push vaccines to "prevent AIDS" when it's the vaccine itself that's most likely responsible for the epidemic to begin with. And beware those flying vaccines.
