From the light weight adidas range favoured by World Marathon Record holder and long distance legend Haile Gereselassie.

The adidas adizero Boston 2 is a serious neutral lightweight distance trainer, built for speed. Made to remain fast and responsive through the toughest training, the adidas adizero Boston laces you into adiPRENE®+ forefoot propulsion, high-impact cushioning and a ventilated shank area to keep your feet cool as they fly.

The Boston 2 brings with it a brand new 3D Formotion unit in the midsole to give a smoother heel-to-toe transition, improved forefoot energy return and surface adaption. New microfibre suede eyes prevent chafing and irritation. The new Boston has a 20g weight loss from it's predecessor and this bodes well for those of you looking for an even lighter, faster running shoe!
