On Running Cloudultra Pro Men's Trail Running Shoes

Built for ultra distance racing on all kinds of terrain. With a CloudTec cushioning system engineered for stability and Helion HF hyper foam for responsiveness and speed.

Breathable Leno Weave Upper

Engineered to provide breathable and durable protection for all your trail adventures. The Cloudultra Pro features a Leno weave upper that creates an optimal internal environment, allowing your feet to stay comfortable and perform their best. This weave comfortably secures your feet, contributing to a smooth and enjoyable run while significantly improving breathability. To prevent overheating and keep your feet feeling fresh mile after mile, the upper includes perforations that promote excellent airflow. This ventilation prevents moisture build up, ensuring your feet remain dry and comfortable throughout your run. The knitted sock construction fits like a second skin and allows an easier step-in, whilst being more lightweight and breathable. A flat-laying tongue sits comfortably against the foot to reduce the chance of irritation. Finally, a traditional lacing system locks the midfoot for a secure fit, helping to prevent in-shoe slippage, the laces have aggressive ridges along the sides for superb grip when laced up.

Dual-Density Helion HF and CloudTec Midsole

Utilising On's Helion Superfoam, the midsole of the Cloudultra Pro keeps you swaddled in a plush comfort underfoot. Ensuring outstanding energy return, experience propulsive boosts to every step while your feet stay feeling soft and fresh, provide you with a soft landing on trails. The foam is double layered to enhance protection and comfort. This has been combined with CloudTec technology to enhance stability over uneven and unpredictable paths. By compressing both vertically and horizontally, CloudTec adapts to personal running styles, boosting confidence and motivation through every stride. Also implemented within the midsole is a fibreglass Speedboard, further adding propulsive energy to your stride and giving you a boost to make every mile easier. Finally, the shoes have been designed with rocker geometry, this technology is where a unique fulcrum effect is created, like a rocking chair, which encourages a guided gait cycle for a more efficient run.

Missiongrip Outsole

Using Finite Element Analysis (FEA), the Cloudultra Pro possesses a Missiongrip Outsole, designed with optimal lug shape, orientation and density to improve grip and traction. Adding speed and efficiency to your run, the rubber ensures better grip on both wet mud and rain-slicked rocks without worry of slipping. The lugs are multi-angled for unparalleled grip when descending and ascending. The outsole construction has a slightly more refined width in the midfoot and forefoot, for a lighter base, and more ground contact and traction. Working alongside this, the outsole includes high-abrasion rubber pods to provide a strong grip on the trail no matter the weather conditions.
