What Makes ON Running Special?
ON Running’s core innovation, CloudTec®, reimagines traditional foam cushioning by integrating a network of hollow pods that adapt to individual stride patterns for personalised comfort. The complementary Speedboard™ serves as an energy transformer, guiding impact energy into a forward roll that increases cadence and reduces fatigue. Each shoe model is engineered for specific running profiles—racing, daily training or off-road—ensuring athletes find the perfect balance of weight, cushion and stability.
Sustainability forms an integral part of ON’s mission. The brand’s Cyclon™ midsole foam, introduced in 2024, is a 100% recyclable cushioning material created from food-grade oils and by-products. ON has also committed to using recycled polyester and bluesign®-approved fabrics in its apparel, reducing waste and carbon emissions across its supply chain while maintaining premium performance standards.
Current Best-Selling Models
Cloud X3 remains a top choice for versatile athletes, combining 14mm heel cushioning with engineered mesh uppers for light weight and breathability during high-intensity workouts. Cloudswift 3, designed for urban runners, features Helion™ superfoam for plush landings on hard surfaces and reinforced sidewalls for stability in fast corners. For long-distance racing, Cloudboom Echo and Cloudboom Echo Pro deliver maximised energy return with a 0-drop platform and aggressive Speedboard™ geometry that elite marathoners trust for record-chasing performances. Cloudventure Peak and Cloudrock Waterproof lead ON’s trail range, pairing grippy Missiongrip™ outsoles with waterproof membranes or durable mesh for off-road adventures.
How Do ON Running Shoes Fit?
ON Running shoes generally fit true to size with a medium-width last that accommodates most runners. Road running models often feel snug in the heel and midfoot to prevent slippage when accelerating, while trail models provide slightly more room in the toe box to allow for foot swelling during long runs. If you have a wider foot or prefer extra room, consider going up half a size, particularly in performance-focused models with engineered uppers.
Women’s and men’s models share the same CloudTec® platform, with size conversions clearly indicated on ON’s size chart—from EU 36 (US 5) through EU 50 (US 16). ON’s online fit guide recommends measuring foot length against a printable sizing tool, ensuring precise selection whether you run on roads, tracks or rugged trails.

Caring for Your ON Running Gear
Proper care preserves cushioning performance and extends the life of ON Running shoes and apparel. For footwear, brush off mud and dirt after trail runs using a soft brush or cloth, then wipe uppers with mild soap and water. Never machine wash or fully submerge performance foams—excess moisture can degrade adhesives and foam integrity. Air-dry shoes at room temperature, avoiding direct heat sources that can warp midsoles and damage synthetic fabrics.
ON apparel features bluesign®-approved fabrics and moisture-wicking finishes that benefit from gentle machine washes at 30°C. Use liquid detergent without fabric softeners to maintain breathability and elasticity. Fasten zippers and Velcro closures before washing to protect high-tech fabrics from abrasion. Hang or lay flat to dry—do not tumble dry—to retain garment shape and functional coatings.
