The Newton Running Shoes Sir Isaac offers intelligent control for all foot types. It is a neutral guidance running trainer designed for those runners who want to improve the efficiency of their running by using the mid to forefoot running style.

The Sir Isaac has been designed by Newton Running Shoes with a beveled heel and toe to help guide the runner easily into the mid and forefoot position. The same design has been used with the lugs to make the running motion smoother and give you a stable feel will in the forefoot position.

It has been manufactured with a wider midfoot, forefoot and lugs to give the shoe an increased stability and a more comfortable feel for you when out running. The manufacturing of the shoe involved using a carbon rubber outsole to make the running trainer more durable and therefore make it last longer.
