The shoe's lasting process allows for a precise fit that accommodates the natural contours of the foot, running tennis shoes for flat feet.

For an adapted and specialized version of our signature CloudTec technology, we left nothing up to chance. Using Finite Element Analysis (FEA), we simulated how each component of our prototype reacts while running. Using invaluable insights from this method, we 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.

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

We're not riding the sustainability wave we're creating our own. To save on water, the Cloudsurfer's yarn is colored using a dope dyeing process that requires 90% less water than standard techniques. We've also ditched the plastic overlays and bumped up the shoe's total recycled content to 30%

The breathable upper material permits air exchange rates 20% higher than industry standards for running footwear, under pronation running shoes.
