This is the new Newton Sir Isaac 2011 running shoes - the latest colour update of the guidance trainer in their range. The Isaac offers 'intelligent control' for all foot types and Newton have designed this trainer for those runners who want to improve the efficiency of their running by adopting a more natural mid to forefoot running style.

Designed with a beveled heel and toe, the Sir Isaac helps guide the runner easily into a natural forefoot strike. A similar design of the unique forefoot lugs, as seen on the performance trainers, help make the running motion smoother and give you a stable feel whilst in the forefoot position. However, there is still protection in the heel to accomodate a 'normal' heel to toe running action.

The Sir Issac has been manufactured with a wider midfoot, forefoot and lugs to give the shoe an increased stability and more comfortable feel for you when out running. The trainer has been manufactured using a carbon rubber outsole to increase durability of the shoe hence making them last longer. Choose this model for a versatile Newton running shoe that will help you improve your running.
