On Frequently Asked Questions

The Cloudmonster 3 runs true to size for most runners, though some users with wider feet report a snug midfoot fit. We recommend ordering your regular running shoe size, but if you have a history of narrow shoe fits, you may want to consider sizing down half a size. On provides detailed size charts on their website to help you find your perfect fit.

The Cloudmonster 3 requires minimal break-in time thanks to its engineered knit upper, which is naturally flexible and breathable from day one. Most runners report comfort during their first wear, though you may want to do a shorter run (3-5 miles) initially to let the Helion™ foam adapt to your foot strike. The shoe typically feels broken in within 1-2 runs.

Yes, the Cloudmonster 3 is designed for long-distance running with its triple-layer CloudTec® cushioning that provides maximum responsiveness and shock absorption over extended miles. The Helion™ foam delivers energy return to reduce fatigue, making it ideal for marathon training and half-marathons. However, some ultralight runners prefer a more minimal shoe, so it's best suited for those who prioritize cushioning over speed.

The Cloudmonster 3 features an updated triple-layer CloudTec® cushioning system that offers improved responsiveness compared to the Cloudmonster 2's dual-layer setup. The knit upper has also been refined for better breathability and a more secure fit around the heel and midfoot. The Helion™ foam in the Cloudmonster 3 provides enhanced energy return, making it a more responsive shoe overall.

The Cloudmonster 3 is available in standard widths, and On does not currently produce a dedicated wide version of this model. If you have wider feet, you may want to check the Cloudflyer or Cloud Stratus models, which tend to have a roomier fit, or contact On customer service for personalized fit recommendations.

The engineered knit upper of the Cloudmonster 3 can be gently cleaned with a soft brush and mild soap mixed with water—avoid machine washing or submerging the shoe. Allow the shoe to air dry away from direct heat or sunlight, which can damage the foam and materials. For stubborn stains, a damp cloth with a small amount of detergent should do the trick without compromising the shoe's integrity.

The Cloudmonster 3 offers more aggressive cushioning than the Nike Pegasus, with its triple-layer CloudTec® providing a bouncier, more responsive feel ideal for runners who want energy return. Compared to the ASICS Gel-Kayano, the Cloudmonster 3 is lighter and more streamlined, though the Kayano offers slightly more stability features for overpronators. The Cloudmonster 3 strikes a balance between cushioning and responsiveness, making it versatile for various running paces.

The Cloudmonster 3 has a durable rubber outsole that holds up well to road running, with most users reporting 300-500 miles of reliable wear before noticeable tread wear. There are no widespread reports of sole separation or major durability issues, though like all running shoes, the foam will gradually compress over time. Regular rotation with another pair of shoes can extend the lifespan of your Cloudmonster 3.

The Cloudmonster 3 comes in multiple colorways including classic black, white, and grey options, plus seasonal colors that vary by region and retailer. On regularly updates their color palette, so availability may change throughout the year. Check On's official website or authorized retailers for the most current colorway options and regional exclusives.

While the Cloudmonster 3 is primarily designed for road running, its responsive cushioning and secure knit upper make it suitable for light gym work like treadmill training or elliptical use. However, it's not recommended for lateral movements or court sports due to limited side support and a design optimized for forward motion. For dedicated cross-training, On offers models like the Cloud Stratus that provide more versatile support.
