Ideal for high mileage road runners who overpronate, the New Balance Men's MR858 Running Shoe supports the foot with a high-tech blend of cushioning and support. The Stability Web and Extended Web arch support system extends into the medial heel area, providing a substantial platform that encourages the foot to roll in a much more neutral manner. Extensive cushioning makes for a smooth ride. In fact, a full length Abzorb pad with special Abzorb SBS heel cushion, a non-cellular elastomer, do the job without performance altering compression. It's resilient enough to aid the pronating runner, yet soft enough to eliminate underfoot soreness. The New Balance MR858 Running Shoe includes 360º reflectivity for superior low light visibility.
