NEWTON Isaac Neutral Guidance Men's Running Shoe

The Sir Isaac Neutral is designed for all levels of running. It is ideal for runners transitioning from a heavy heel strike to a comfortable midfoot landing position. For those that have the philosophy of running as naturally as possible, this shoe promotes greater efficiency and less overuse injuries (like achilles tendonitis and plantar fasciitis). Recommended for any running distance, walking or general fitness.

It includes a bevelled heel and toe to guide the footstrike effortlessly into the midfoot and forefoot, while bevelled lugs feel smoother and more gradual in the forefoot. The wider design adds a softer feel and greater stability, and this is supported by the midfoot chassis/shank.

The carbon rubber outsole offers increased durability and closed mesh on the upper helps small debris firmly on the outside.
