This is CloudTec Phase™

For an adapted and specialized version of On's signature CloudTec® technology, they left nothing up to chance. Using Finite Element Analysis (FEA), On simulated how each component of their prototype reacts while running. Using invaluable insights from this method, they created the optimal midsole for a seamless weight transfer from heel to toe. It's called CloudTec Phase® and it introduces a new age of cushioning.

But why Phase?

In CloudTec Phase®, the computer-optimized Clouds seamlessly collapse like dominos when your foot lands. The result? Supreme, enhanced cushioning, and a softer, smoother transfer from heel to toe.

Less plastic, less water

To save on water, the Cloudsurfer's yarn is coloured using a dope dyeing process that requires 90% less water than standard techniques. On also ditched the plastic overlays and bumped up the shoe's total recycled content to 30%.
