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 does this with a combination of Flytefoam™ technology and Gel™ technology. The rigid front piece and dynamically curved sole increase performance by reducing ankle joint movement. The shoe's center of mass is closer to the heel, making it easier to rock the foot forward.
