With an updated upper and even softer cushioning, the On Cloudultra 2 Shoe keeps our feet feeling fresh as we train for long-distance races. The Cloudtec cushioning absorbs repeated impacts, and the Helion superfoam gives extra padding across rough and rocky terrain. We spring forward with every stride, thanks to the bouncy Speedboard, and the updated lug layout provides incredible ground contact to give us unparalleled traction over technical terrain.
