With a design closer to traditional running shoes, the Newton Sir Isaac features moderate cushioning and a semi-soft ride.
The Newton Sir Isaac is a good starting point for runners seeking a more "natural" foot landing position. The shoe design encourages midfoot and forefoot striking, while the actuator lugs absorb impact and return energy. Best suited for runners looking for a daily training shoe with a focus on durability and protection.
The Sir Isaac is a moderate feature, moderate neutral shoe designed for racing, daily training and high mileage.
