The reactions we've had from present Newton runners have been positive. Having five lugs on the sole instead of four puts one lug at each edge of the forefoot, which gives a more stable feeling side-to-side. The Gravity and Distance keep their low drop from heel to toe.
The Energy, which is a shoe Newton added to their lineup last year, has a larger drop than the Gravity or Distance (6mm versus 3mm for the Gravity, 2mm for the Distance), more cushion and more rubber on the sole. It's surprisingly light, though. The Energy is meant to be an introductory shoe for people who want to move to a forefoot strike from a heel strike. The sole will hold up to heel striking, which tends to afflict us as we fatigue and our form deteriorates, and the larger heel-toe drop is closer to the drops of traditional running shoes to help ease you through the transition to forefoot running.
