Over the past decade, the men’s Guide ISO Running Shoe has been setting the pace as a stability shoe for mild-to-moderate pronators. It features continuous EVERUNTM topsole, which improves energy return and cushioning. A PWRFOAM midsole design reduces fatigue-causing vibrations while providing excellent stability. This medial posted midsole also helps effortlessly facilitate transitions with every stride. Saucony’s innovative ISOFIT design creates a more refined and dynamic fit system by adapting to the shape and motion of your foot. Engineered mesh uppers have some extra structure thanks to lightweight and robust FLEXFILM overlays that provide a flexy and seamless feel.
