CloudTec Phase®

Computer-optimized cushioning

To enhance the CloudTec® sensation, we left nothing up to chance. Cutting-edge FEA technology (Finite Element Analysis) enabled us to create a sequentially collapsing midsole. This way, CloudTec Phase® can make your run even smoother. Cloud after Cloud.

A new dimension of cushioning

You land, you take off – it's that simple. Or is it? Slow down the process and you'll see: What happens between landing and takeoff is crucial to your comfort. That's why CloudTec Phase® emphasizes both soft landings and a seamless weight transfer from heel to toe.

FEA explained: Where human intuition meets computer-optimization

With specialized FEA software, our engineers in the On Lab create virtual prototypes to analyze, test and optimize every component. The benefits? More upgrades to a shoe with fewer physical prototypes. In our search for the optimal cushioning sensation, this scientific method helped us identify Clouds' optimal shape, size and alignment. But, no science could truly explain what it's like to experience CloudTec Phase® technology – you'll have to feel it to believe it.

Double cushion. Dreamy ride.

Why stop at one? With two layers of CloudTec Phase® cushioning, the Cloudeclipse offers a dream-like ride over long distances. The soft, super-stacked midsole collapses in sequence as your feet hit the ground. For pillowy landings, effortless push-offs and a ride that's smooth as butter.
