Description
xThe On Cloudboom Max represents the ultimate expression of raw speed and elite performance from On Running. Engineered specifically for high-stakes racing and high-intensity training, it pushes the boundaries of responsiveness and lightness to the maximum limits allowed on the road.
Here is what makes this model a true speed weapon:
Helionâ„¢ HF (Hyper Foam) Superfoam
This is the heart of the beast. The Cloudboom Max utilizes the latest Helion™ HF Pebax foam—the Swiss brand's highest-rebounding and lightest compound to date.
-
Designed to deliver maximum energy return, this foam absorbs impact forces and instantly snaps back with every stride.
-
It allows you to maintain a grueling pace over long distances (half-marathon to marathon) while significantly reducing muscle fatigue.
The Carbon Speedboard® Plate
Sandwiched between two thick layers of superfoam, the Carbon Speedboard® plate is aggressively shaped.
-
Its extreme rigidity creates a powerful lever effect that literally catapults the runner forward.
-
Combined with an ultra-pronounced rocker (sole curvature) at the forefoot, it optimizes the transition phase to minimize ground contact time.
Minimalist Design and Absolute Lightness
Every single gram of superfluous weight has been stripped away to focus entirely on speed:
-
Single-Component Mesh Upper: The upper is made of an ultra-breathable, near-transparent woven mesh that hugs the foot like a second skin while ensuring excellent lockdown, even through tight corners.
-
High-Precision Grip: The outsole features technical rubber strategically placed only on key impact zones, guaranteeing maximum traction on wet or dry asphalt without adding unnecessary bulk.
In short: The Cloudboom Max is a powerhouse of carbon technology and next-generation foam. It is the uncompromising choice for competitive runners looking to crush their personal bests from the 10K to the full marathon.
