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.
