Max-Cushioned Speed for Ultra-Distance Racing

When you are staring down 100 kilometres of technical singletrack, logging massive vertical gain, and pushing your body to its absolute limit, your footwear needs to be as relentless as you are. The On Men's Cloudultra Pro is engineered specifically for the extreme demands of ultra-distance trail racing. Moving away from overly rigid designs, this shoe balances aggressive, race-day propulsion with the deep, protective comfort required to keep your legs turning over deep into the pain cave.

The engine of the Cloudultra Pro is powered by a dual-density Helion™ HF hyper foam midsole, delivering an incredibly responsive, high-energy return that actively works to keep your pace up when fatigue sets in. This is paired with a specialized CloudTec® cushioning system tuned specifically for off-road stability, ensuring you don't roll an ankle on unpredictable terrain. Driven forward by a reinforced fiberglass Speedboard® and locked to the trail with a high-traction Missiongrip™ outsole, this is a top-tier racing weapon built to conquer everything from root-heavy Canadian coastal trails to dusty alpine ascents.

Key Features

Helion™ HF Hyper Foam: A premium, dual-density midsole that delivers massive energy return and hyper-responsiveness to keep your speed high during long efforts.
Engineered CloudTec®: Maximized cushioning system purposefully tuned for trail stability, absorbing harsh impacts on descents while keeping your foot securely planted.
Fiberglass Speedboard®: A stiff, reinforced fiberglass plate embedded in the midsole that snaps you forward, providing race-day propulsion and explosive toe-offs.
Missiongrip™ Outsole: High-performance rubber compound with aggressive, multi-directional lugs for unshakeable grip on mixed terrain, wet rocks, and loose dirt.
Quick-Drying Upper: A highly breathable, lightweight upper that rapidly sheds water and sweat, preventing blister-causing moisture buildup over long distances.

Best For

The Terrain: All-terrain versatility. From aggressive, rooty singletrack to long stretches of packed dirt and fire roads.
The Effort: Ultra-marathons, long-distance trail racing, and high-output fastpacking where speed and max protection are equally important.
The Conditions: Four-season racing; the quick-drying upper actively sheds water from stream crossings, while the Missiongrip™ locks down on wet or dry surfaces.
