Editor's Notes
- What is Natural running? For over 15 years Boulder Colorado based Newton Running has been studying how humans run (without footwear) on a natural surface. The foot plant is light and contacts the ground mid foot or forefoot first , sensing the ground , body mass is over the landing mass for balance, heel settles downward after touchdown to allow the lower body muscle and tendon to load and recoil energy, upper body leans slightly forward to allow gravity to pull us forward and the cadence is quicker to self regulate impact and keep up with the forward pull of gravity. It feels light and easy! Take your shoes off and run across the floor, notice how the body automatically knows how to run correctly.This is Natural Running! This is the way we were all born to run!From this information Newton Running shoes were developed to be a more natural extension of your foot. Allowing the runner to be centered with gravity. Allowing the foot to work with the shoes more naturally. Maximizing sensory input, energy return and shock absorption for Unnatural surfaces.

- Natural Running Form with Newton Running shoes. Without high heel pitch the foot sets up parallel to the landing surface. The foot lands under the body mass mid foot/ forefoot , heel settles to the ground recoiling spring tension from the lower body.Now simply lift the foot off the ground instead of pushing.Repeat.Upper body stays slightly forward , shoulders square, elbows pull back , arms relaxed and at 90 degrees head stays level and looking forward.
