To save on water, the On Cloudsurfer Running Shoe's sustainable 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%. 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.
