What Our Gearhead(R) Experts Are Saying:"I've logged back-to-back long runs in the Cloudultra Pro, and the balance between cushioning and control is unreal. It feels springy without being soft, stable without being stiff. The updated Missiongrip outsole really bites into tricky terrain, and the Leno weave upper is breathable even during hot, exposed climbs. It's made for serious mileage with pro-level precision."On's Cloudultra Pro is a trail shoe built for endurance-minded runners who want to go longer, faster, and more efficiently. Tested in elite ultra-distance events and shaped by performance-driven design, it delivers the cushion, control, and traction needed to stay strong across rugged elevation profiles and ever-changing terrain.

The Missiongrip(TM) outsole has been fully redesigned for maximum traction with a refined lug layout that grips over wet roots, loose descents, and rocky traverses. Zoned Leno weave in the upper promotes breathability while offering strategic support where it matters most. Light, fast, and engineered to conserve energy over long distances, the Cloudultra Pro is race-day ready for mountain-minded runners.
