The 870 from New Balance is one smooth operator. It offers plenty of ground contact through the midfoot, which results in a smooth, responsive ride. With support for mild to moderate over-pronation and a hint of a go-fast feel, the 870 is great for runners who like a good road feel and a sense of get up and go.
The 870 is a moderate feature, moderate support shoe designed for daily training and high mileage. It is built with a curved shape.
