The CloudSurfer Next in Glacier presents a refined take on the responsive running shoe. This iteration combines On's signature CloudTec cushioning technology with a streamlined silhouette designed for both road and versatile training. The monochromatic glacier colourway—a cool, composed white-grey palette—delivers understated sophistication.
Built for runners seeking a lightweight, responsive experience, the CloudSurfer Next balances comfort with purpose-driven performance. The clean aesthetic ensures effortless integration into any active wardrobe, making it equally at home on morning runs or casual daily wear.
Every pair is brand new and unworn, supplied in its original box. Nothing we sell is used, worn or ex-display — just deadstock, ready to wear.
Every pair is verified 100% authentic in-house before it ships — checked against known-authentic references for materials, stitching, labelling and box details.
Fast UK tracked delivery, with next-day options at checkout. Orders are dispatched securely and double-boxed to protect the shoe box in transit.
