If speed is your motivation, the DS TRAINER NC delivers, whether it's building up speed with twice-a-week interval training or taking aim at that sub-3 marathon. It's lighter than ever so your feet get off the ground easier with every stride. Plus, you get springy push offs thanks to the stabiliser in the sole that channels your energy into the forefoot. Go faster on long-distance runs from 10 to 42 kilometres Built for neutral runners taking aim at landmark times Grip the road with every stride thanks to the lightweight material in the forefoot Perfect for training runs before switching to the DS RACER on race day
