Newton Gravity 6 £127.95

A perfect shoe for fast neutral runners who like to get up on their toes; the signature forefoot lugs are softer and springier and the heel cushioning improved. The former was noticed by testers, but not the latter. Unless you’re an experienced Newton wearer or have good core strength this is best kept for short-to-medium runs, owing to the strong posture required. And if you’re planning to buy Newtons for the first time, build up your distance slowly to allow your calves to adapt.
