On Frequently Asked Questions

Yes, the Cloudultra 3 runs true to size for most runners. On recommends ordering your normal shoe size, though some runners with wider forefeet report going up a half size for extra comfort on long trail runs. If you're between sizes, consider your typical sock thickness and any foot swelling during extended wear.

The Cloudultra 3 has minimal break-in time thanks to its soft Leno weave mesh upper and responsive Helion™ HF foam. Most runners report the shoe feels comfortable right out of the box, though you may want to do a shorter 3-5 mile run first to ensure the fit works for your foot shape before tackling longer trails.

The Cloudultra 3 has a standard fit and isn't specifically designed for wide feet. However, the flexible mesh upper and spacious toe box work well for many runners with moderate width feet. If you have very wide feet, trying the shoe on or checking On's return policy before purchasing is recommended.

The Cloudultra 3 features On's dual-layer Helion™ HF foam, which delivers maximum energy return and plush cushioning without sacrificing ground feel on technical terrain. This makes it ideal for long trail runs where you want protection from impact while maintaining responsiveness for quick directional changes.

The Cloudultra 3 is built for durability with a reinforced Leno weave mesh upper that resists abrasion and tears from brush and rocks. The Missiongrip™ rubber outsole is specifically engineered for technical terrain, providing excellent traction and protection against punctures on sharp surfaces.

While the Cloudultra 3 is designed primarily for trail running, its responsive cushioning and durable construction make it suitable for mixed-terrain running that includes some road sections. However, for pure road running, On's road-specific models like the Cloudflow would be a better choice due to their lighter weight and road-optimized geometry.

Clean the Cloudultra 3 by hand with cool water and a soft brush to remove dirt and mud from the mesh upper and outsole. Avoid machine washing and direct heat drying, as this can damage the foam and adhesives; instead, air dry at room temperature away from direct sunlight.

The Cloudultra 3 offers a more responsive and cushioned ride compared to the Speedcross, making it better for longer distances, while the Speedcross excels in aggressive downhill traction. Versus the Gel-Trabuco, the Cloudultra 3's Helion™ foam provides better energy return, though the Trabuco offers slightly more stability for overpronators.

The Cloudultra 3 comes in multiple colorways including classic black, vibrant trail-ready colors, and seasonal editions. Colorway availability varies by region and retailer, so checking On's official website or authorized dealers will show you the current options in your area.

The Cloudultra 3 has a solid track record with no widespread reports of sole separation or major durability issues. Some users report minor squeaking in the heel area during the first few runs, which typically resolves as the shoe settles; if it persists, contact On's customer service for support.
