The Newton Sir Isaac S provides support for over-prontation while encouraging a midfoot/forefoot striking pattern. Thanks to actuator lugs in the forefoot, the Sir Isaac S provides excellent shock absorption and energy return. This shoe is great choice for runners who have been in traditional support shoes, but now want to try moving up on the foot to be more "natural".
