The GLIDERIDE is a product that allows runners to run longer and more enjoyably with less effort. The distinctive and bold curved sole structure, GUIDESOLE, reduces ankle movement from landing to kicking, increasing running efficiency and reducing the runner's energy consumption. In addition, the slightly firmer midsole material in the forefoot provides excellent strength, making it easier to create a smooth and effortless rolling motion that propels the foot forward when running. This new model is recommended for a wide range of runners, from running beginners to sub-5 to sub-4 runners aiming to improve their times, and even elites who are training hard.
