On Cloudultra 3 Men's Trail Running Shoes - Black/Black - EU 42.5

Built for the long haul, the On Cloudultra 3 redefines ultra-distance comfort with its adaptive cushioning and rugged grip. Unlike typical trail shoes that sacrifice energy return for protection, this model pairs CloudTec® with Helion™ superfoam to keep every stride lively, even after hours on technical terrain. The black-on-black colorway keeps the look understated, while the engineered mesh upper with TPU reinforcements delivers a secure, breathable fit. Whether you're chasing a personal best or exploring new ridgelines, the Cloudultra 3 is ready to go the distance.

Highlights

• CloudTec® cushioning with Helion™ superfoam for long-lasting comfort and energy return
• Missiongrip™ rubber outsole for reliable traction on varied and technical trails
• Engineered mesh upper with TPU reinforcements for durability and breathability

In daily use

From the first step, the Cloudultra 3 feels balanced and responsive. The Helion™ superfoam midsole absorbs impact without feeling mushy, while the Missiongrip™ outsole bites into loose dirt, rocks, and mud. The upper wraps the foot securely, and the FlipRelease™ tool lets you fine-tune the fit without stopping. At just 295 g per shoe, it's light enough for racing yet durable enough for daily training. The black/black design hides trail dust and pairs easily with any kit.
