Saucony - Grid Shadow 8 (White/Navy/Gold) - Men's: A well cushioned, durable trainer with a long heritage of fit and performance. Designed for neutral to slight over-pronators that like a heavier, stiffer ride. Polyurethane in the heel to withstand the heavy heel strikes of larger neutral runners. Visible Rearfoot Grid System provides superior cushioning and stability by centering the heel on impact. Forefoot HRC (High Rebound Compound), a responsive EVA/rubber compound, provides cushioning through the later stages of the gait cycle. Arch-Lock Midfoot Wrap provides superior control and support. Midfoot Support Bridge, a rigid material in the shank area of the midsole, keeps the foot neutral in the midfoot phase of the gait cycle. Flex grooves allow the shoe to bend and flex properly with the natural motion of the foot. XT-600 carbon rubber outsole material offers outstanding abrasion and traction properties. Shoe weighs 12.0 oz.
