On Cloudultra Pro

The On Cloudultra Pro is On’s ultra-distance trail racer built to help you stay efficient when the hours stack up and the terrain keeps changing. A dual-density Helion™ HF hyper foam midsole pairs with On’s CloudTec® geometry to deliver a fast, responsive feel while keeping the ride stable enough for long descents and tired legs. Underfoot, a reinforced Speedboard® adds propulsion and encourages a smooth roll forward. Up top, a breathable, quick-drying Leno weave upper is made for heat, dust, and high-mileage efforts.
