The training shoe with computer-optimized technology for next-level cushioning. Description This is CloudTec Phase For an adapted and specialized version of On's signature CloudTec® technology, we left nothing up to chance. Using Finite Element Analysis (FEA), we simulated how each component of their 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. Less plastic, less water On is not riding the sustainability wave – they are creating their own. To save on water, the Cloudsurfer's yarn is colored using a dope dyeing process that requires 90% less water than standard techniques. They've also ditched the plastic overlays and bumped up the shoe's total recycled content to 30% Fabric Total recycled content: about 30% – Total recycled polyester: about 85% Dimensions Weight: 205g Cushioning: Plush Heel to Toe Drop: 10mm Road Running Style: Neutral Worn less than 5 times - EUC - like new honestly.
