ACTION/REACTION TECHNOLOGY™

The genius behind the Newton running shoes is the patented Action/Reaction Technology™. When using the ultra-efficient Land-Lever-Lift natural running gait of a midfoot or forefoot strike, the technology absorbs and then returns energy back to you. It's a revolutionary way of building a running shoe based on Sir Isaac Newton's Third Law of Motion: "For every ACTION, there is an equal and opposite REACTION."

How it Works

When your midfoot/forefoot LANDS on the ground, the technology's four external actuator lugs are pressed into hollow chambers inside the shoe's midsole via an elastic membrane (ACTION). This movement absorbs shock.

As you LEVER inside the shoe, the lugs release their stored energy and propel you forward through a burst of energetic return (REACTION) from the Action/Reaction Technology™. You then LIFT your knee and begin a new stride.

Most running shoes use various forms of air, gel, foam or plastic to counteract the foot's impact and response with the ground. But none of these materials capture and return energy like our Action/Reaction Technology™. With independent laboratory testing, 9 US Patents (other US and foreign patents pending), two Ironman World Championships, numerous world records and personal records, Newton Running shoes are superior to any other running shoe technology.
