Barefoot running was clearly one of the most talked about trends in the running industry last year. From the bestselling book Born To Run, to the explosive growth of the Vibram Five Fingers, runners everywhere seem to be talking about barefoot running.
Well, the buzz about barefoot running is about to hit a fever pitch. As we’ve talked about in previous posts , Harvard anthropologist Dan Lieberman has been studying the evolution of human running for several years. Dr. Lieberman has just published the results of his study in the journal Nature and the mainstream media is running (cough) with the story. For those of you who listen to NPR on the drive home, you might have heard this story on “All Things Considered” today. The story is also available on NPR.org and features a pretty interesting video:
Not surprisingly, Vibram Five Fingers are also getting a lot of attention from the media (Vibram sponsored Lieberman’s study). The Five Fingers clearly help people to try barefoot running, while providing some protection from rocks, glass, etc. As we talked about in the previous post , Newton’s are built for Natural Running but some of you may be wondering how Newtons compare to Vibrams. Amanda Brooks asked just that on her blog, Run to the Finish , and Newton Running’s Director of Education and Research, Ian Adamson, had this response:
Running Newton Shoes and Vibram Five Fingers have many similarities, at least from a form perspective. The primary difference is the cushioning and energy return provided by Newtons, which is largely absent in Vibrams.
Both Newton Performance Racers and Vibrams have a 2 mm heel lift, or toe drop depending on how you look at it. This translates into a 1.3% down grade in the shoe, also referred to as ramp angle or drop. Newton Performance Trainers have a 2% gradient, which although very small, can be felt by aware runners. Regular running shoes have a much steeper angle, up to 15% depending on the shoe.
Barefoot running forces you to run efficiently and preventatively with respect to injury. Vibram’s allow people to experience barefoot running with an added layer of protection from harsh surfaces, while Newton’s go one step further, adding forefoot cushioning and a significant energy return component.
Newton shoes are much kinder to the body’s structure and musculature when transitioning from a traditional running shoe to barefoot, and allow you to perfect a natural (barefoot) form while providing protection and cushioning. Newton’s active membrane technology has been carefully designed to facilitate afferent feedback, which means the nerves in your forefoot feel the ground very quickly through the shoe. This is achieved through the outer lugs and internal semi-rigid chamber that is connected to the bio-mechanical top plate adjacent to your foot inside the shoe.
Traditional shoe cushioning mechanisms dampens afferent feedback, hampering proprioception and thus hindering your ability to self-regulate the impact of your foot strike. Studies show that runners strike much harder in shoes that dampen afferent feedback, one of the causes of injury. Barefoot runners and runners in shoes that allow you to sense the ground encourage you to run protectively, as if barefoot.
Bottom line is that both Vibrams and Newtons encourage a barefoot or natural running style, but Newtons make it much easier for runners to transition from typical running shoes.
