Trail2025-06-19 · JP · ReleaseChecked 2026-10-27

Cloudultra Pro is built for ultra-distance trail racing across varied terrain. A stable CloudTec platform pairs two densities of Helion HF foam with a fiberglass-reinforced Speedboard. Its revised Missiongrip lugs were shaped with computer analysis for traction over changing ground. The breathable, quick-drying upper is intended for long efforts where maintaining pace matters.
