On Cloudflow 5 – Super Trainer Speed for Every Runner

The On Cloudflow 5 is completely reengineered to deliver race-inspired speed for tempo runs, intervals, and high-performance daily training. Designed as the super trainer counterpart to On’s elite Cloudboom series, it blends fast-paced energy with the durability and comfort you need for consistent mileage.

Underfoot, a top layer of Helion™ HF superfoam—borrowed from On’s pinnacle race shoes—delivers explosive energy return, while a bottom layer of standard Helion™ foam with CloudTec® cushioning keeps the ride smooth and versatile. Between them, the nylon and glass fiber Speedboard® adds snappy propulsion, and the rockered midsole geometry ensures seamless, efficient transitions from heel to toe.

The ultralight woven mesh upper maximizes breathability and now features extra forefoot room for comfort at speed. A grippy rubber outsole delivers reliable traction, while wrap-around toe bumpers and bold On branding mirror the look of the brand’s top-tier race shoes.

Whether you’re chasing PRs in training or want a light, fast shoe for everyday runs, the On Cloudflow 5 brings race-day tech to your daily miles.

UPPER

• Helion foam is On's signature blend of EVA and OBC (Olefin Block Copolymer) for better bounce and all-around performance than standard EVA. 
• Full-length Speedboard is performance nylon blended with 8% glass fiber for springy propulsion that's ideal for daily training, more flexible than carbon. 
• CloudTec elements help create On's instantly recognizable look and performance.
