Men's Cloudultra 3

The Cloudultra 3 is On's mileage-first ultra shoe — single-layer Helion HF, aggressive Missiongrip lugs, Leno-weave upper for quick drainage and drying. The Cloudultra Pro is the race-tuned version: same HF philosophy in a lighter, more race-tuned package (269 g M9, 39 mm / 33 mm / 6 mm drop), built for the sharp end of the ultra field. Both share the 6 mm drop and the Leno-weave construction. Cloudultra 3, single-layer Helion HF, Leno-weave upper, aggressive Missiongrip lugs. Built for mileage (295 g M9), not for podium pace.
