On Cloudflow 5 - Engineered for speed and tempo

The On Cloudflow 5 brings race-day technology to your fast training sessions. Built specifically for short and mid-distance efforts, this performance trainer combines CloudTec® cushioning engineered for speed with Helion™ HF hyper foam that delivers maximum energy return when you're pushing the pace.

Speed-Focused Cushioning System

CloudTec® cushioning provides the responsive platform needed for tempo runs and speed drills without feeling sluggish underfoot. Paired with Helion™ HF hyperfoam in the midsole, you get maximum rebound that converts impact into forward propulsion. A glass fiber-infused nylon-blend Speedboard® works with the enhanced rocker geometry to create a fast, propulsive ride from the first stride.

Race-Inspired Construction

The engineered woven mesh upper balances breathability with ultralight construction—keeping weight minimal whilst maintaining structure during hard efforts. Large logo detailing and eye-catching grip pads on the updated toe box mirror the design of On's elite racing shoes, whilst the forefoot grip provides added support during the toe-off phase when you're accelerating.

Built for Fast Sessions

The enhanced rocker shape encourages natural forward momentum, making it easier to maintain pace during sustained tempo efforts or interval sessions. The updated toe box design accommodates the foot's natural splay during faster running, whilst maintaining control through transitions.

Is the Cloudflow 5 right for you?

Designed for runners who incorporate regular speed work, tempo runs, or interval sessions into their training. The Cloudflow 5 suits those running short to mid-distance efforts where pace matters—typically 5K to half marathon training. It particularly benefits runners who want a lighter, more responsive shoe for quality sessions but still need enough cushioning for sustained efforts at threshold pace. Whether you're drilling 400m repeats on the track, logging tempo runs at race pace, or mixing speed work into your training week, this shoe handles the demands of fast, controlled running without the racing-flat minimalism that some find uncomfortable for training volume.
