The Glideride™ shoe allows you to run longer while consuming less energy. It features Guidesole™ technology for improved shock absorption and reduces muscle load on the foot. It achieves this with a combination of Flytefoam™ technology and Gel™ technology. The stiff forefoot and dynamically curved sole increase efficiency by reducing ankle joint movement. The shoe's center of mass is closer to the heel, making it easier to swing the foot forward.
