Description The Cloud with Zero-Gravity foam and On's patented Swiss Cloudtec® technology is the lightest running shoe in the world, with outstanding cushioning and impact protection. In other words, reduced to the pure maximum. Experience the combination of a soft landing with an explosive takeoff for an unbelievably light running sensation. Seperated by a central channel, the Cloudtec® sole responds to your individual gait. The Cloud elements are affixed directly to a semi-transparent Speedboard allowing each Cloud element to move individually.
