| CLOUDTEC® | This foam results from the combination of innovative materials and ultra-precise geometry. It will cushion your sets and strides. The CloudTec® technology is paired with a responsive foam to adapt to each stride. The result? Compression that is both horizontal and vertical in response to your movements, providing impact absorption and multi-directional support. |
| MISSIONGRIP™ | Missiongrip™ uses a technical rubber to maximise friction and master all terrains. Designed and tested with On Running athletes in the Swiss Alps, the Missiongrip™ rubber was created with one goal: to provide perfect grip, stability, and anchoring, from wet trails to the most ambitious circuits. |
| SPEEDBOARD® | Speedboard® technology optimises propulsion at every stride thanks to a plate designed to flex at the forefoot and promote a dynamic roll-off. Its material, shape, and stiffness are carefully adjusted to offer the ideal balance between stability, energy return, and comfort. The stiffer the Speedboard®, the more it delivers a sensation of power and responsiveness, while softer versions favour a smooth and natural stride. |
