Designed as a fast-paced shoe, it quickly proved to be much more than that, just as capable during long, moderate training sessions and sprints to the finish line. The energy-efficient PWRRUN PB foam springs back with every step, combined with a winged nylon plate that offers torsional rigidity while maintaining flexibility in the forefoot, for a stable and responsive ride. The SPEEDROLL technology ensures effortless speed and a forward-moving momentum you can rely on every day.
An increased amount of rubber covers the heel, extending higher on the shoe and around the edges for added durability. A longitudinal groove running the entire length for increased flexibility and a more natural, smooth transition in your stride cycle. A brand new designed mesh, lightweight for your fast-paced efforts, and made for comfort so you can enjoy them every day.
