In the competitive world of performance running, innovation is the ultimate marathon. Enter the On Running Cloudboom, a shoe that represents not just a product, but a philosophy forged in the heart of the Swiss Alps. The story begins with On’s founding principle: to create a running sensation akin to "running on clouds." While the iconic CloudTec® cushioning system solved the comfort puzzle, a new challenge emerged—how to channel that soft landing into explosive, efficient forward propulsion for the world's fastest runners.
The Cloudboom is the answer to that call for pure speed. It is the culmination of years of research, biomechanical study, and collaboration with elite athletes. Unlike On’s daily trainers, the Cloudboom is a dedicated racing weapon, designed explicitly for marathon race day. Its development was driven by a clear goal: to minimize energy loss and maximize energy return with every stride. This led to the creation of a unique, carbon-infused Speedboard®. This plate isn't just rigid; it's engineered to work in harmony with the advanced Helion™ superfoam, creating a propulsive "kick" that launches runners forward.
Visually, the Cloudboom is unmistakable. Its sleek, asymmetrical upper is crafted from a lightweight, engineered mesh that provides a precision fit without excess material. The outsole reveals the shoe's soul—strategic grip pads replace a full rubber layer, shaving off precious grams. Every component, from the aggressive rocker geometry to the minimal tongue, is interrogated for its contribution to velocity. This is a tool for runners who understand that on race day, every second is a battle against the clock.

More Than a Shoe: A Testament to Iteration
The Cloudboom’s brand story is ultimately one of relentless iteration. It wasn't born in a single eureka moment but through countless prototype iterations, wind tunnel tests, and feedback loops with athletes like three-time Olympic medalist Hellen Obiri. Each version refines the formula, pushing the boundaries of what's possible in racing footwear. The shoe symbolizes a bridge between Swiss precision and the raw, unbounded ambition of a runner chasing a finish line.
"The Cloudboom is not for your daily training run. It is a carefully calibrated instrument reserved for the day that matters most. It encapsulates our mission to disrupt, to engineer, and to unlock human potential."
Today, the On Running Cloudboom sits at the pinnacle of the brand's lineup. It’s a statement piece that proves On can compete at the highest echelons of running technology. For the marathoner seeking a combination of responsive cushioning, aggressive propulsion, and lightweight agility, the Cloudboom offers a distinct, Swiss-engineered path to the podium. It turns the dream of running on clouds into the tangible, thrilling reality of running faster than ever before.
