On Unveils the Next Era of Running Innovation: The Fusion of SURREAL Superfoam and CloudTec®
In the Cloudsurfer 3, the Swiss sportswear brand combines its new superfoam, SURREAL, with CloudTec Phase™ cushioning for a softer, smoother ride

ZURICH, Switzerland, December 8, 2025 – On, the premium Swiss performance sportswear brand, today announced a structural engineering breakthrough, combining its newly-created superfoam—SURREAL—with On’s iconic CloudTec® cushioning system. Based on specialized Finite Element Analysis simulations conducted at On Labs, the combination of these two technologies—a first for On and the industry—is predicted to result in significantly greater impact absorption than with SURREAL foam alone.
“Innovation at On is about obsessively making the best possible products that push the limits of sensation and performance, continuously reimagining what the run can feel like,” says Scott Maguire, Chief Innovation Officer at On. “The fusion of SURREAL foam and CloudTec® cushioning is our superpower. This is a fundamental enhancement to our core technology that we believe will elevate the performance and experience for runners of all kinds.”
A Landmark Achievement in Swiss Engineering
On’s engineers achieved this technological advancement through multiple years of material innovation, structural engineering, and biomechanical testing in On Labs Zurich. Using computer-aided engineering, On’s innovation team can now apply this breakthrough to Cloudsurfer 3 and other products, crafting new levels of performance and sensation.
Caspar Coppetti, Co-Founder of On, adds: “Innovation has always been at the core of our DNA. From the first prototype in the Swiss Alps to the global stage, On was built on a radical belief: that performance in running can be redefined when form and function come together in entirely new ways. For the past 15 years, our engineering team has turned that belief into reality through constant innovation. Next, we are confident the fusion of SURREAL foam and our signature CloudTec® cushioning will revolutionize the running sensation for years to come.”
Introducing Cloudsurfer 3
On will introduce this breakthrough technology in the new Cloudsurfer 3, which debuted at The Running Event in San Antonio, Texas, December 2-4, 2025.
The redesigned Cloudsurfer 3 is a premium performance running shoe that offers a softer, smoother ride, achieved through the combination of On’s CloudTec Phase™ cushioning system and SURREAL foam. This pairing adapts in real time—helping to absorb impact and guide heel-to-toe transitions in a seamless roll.
Beginning with Cloudsurfer 3, SURREAL foam is set to become a core technology used across On’s performance range, adding to On’s existing portfolio of Helion and Helion HF foams.
