This Neutral Performance Trainer is for runners wanting a daily training shoe that can also function brilliantly as a faster tempo-pace run or race shoe. More supportive and structured than Newtons lightweight performance trainer line, the Gravity is a great everyday trainer for runners who may like to turn up the speed now and again during tempo or fast-paced runs and intervals.
gravitas=gravity Newton Women's Neutral Performance Trainer Newton Running's top-of-the-line neutral performance trainer is the ultimate shoe for Natural Running. Get a fast, flexible ride with greater energy return and less impact. The 2010 model has enhanced durability in the heel, a new high-rebound midsole material and improved upper fit. This shoe allows you to run naturally — faster with greater efficiency and less overuse injuries (like achilles tendonitis and plantar fasciitis). Recommended for any distance just like its complimentary race-day partner, the Neutral Performance Light Weight Trainer/Racer. For new customers, our shoes tend to fit smaller than many common running shoes With every shoe there is an adjustment period As Newton transitions between last year's color and the new color (shown here), Triathlon LAB has limited stock of each color. Please call to confirm color availability in your size.

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.
