Cruise the concrete in this ultrasoft road running shoe. With CloudTec Phase® cushioning for a smooth ride and seamless heel-to-toe transition. THIS IS CLOUDTEC PHASE™ For an adapted and specialized version of our signature CloudTec® technology, ON left nothing up to chance. Using Finite Element Analysis (FEA), they 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 ON is not riding the sustainability wave – They're 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%.
