OverviewThe Women's Cloudultra Pro is the race-tuned end of On's ultra line in a women's fit. It carries the same Helion HF philosophy as the mileage-first Cloudultra 3, sharpened into a lighter, more race-focused package on a 39 mm / 33 mm platform with a 6 mm drop — built for the sharp end of the ultra field. The Leno-weave upper drains and dries quickly, and Missiongrip lugs keep it planted on the technical ground where long races are won and lost.DetailsBest for:100-mile and 100-km trail ultras raced at paceKey long sessions in an ultra buildWet, technical trail where drainage mattersRunners who want Helion HF on technical terrain in a women's fitSpecs:Category: Top-tier ultra racerStack: 39 mm heel / 33 mm forefoot (lab-measured where available)Drop: 6 mmMidsole foam: Helion HF hyper-foam, dialled race-tunedPlate: Speedboard (trail-tuned)Outsole: Missiongrip rubber with aggressive trail lugsUpper: Leno-weave, breathable, quick-drying; abrasion-resistant overlaysMaterials & CareDesigned in Zurich.
