About this product
A mesh upper gives the On Running Cloudsurfer Trail 2 Rock Niagara a finely textured, lightweight-looking finish. The material’s open structure adds visual detail without making the presentation feel busy. Its Rock Niagara colourway brings a distinctive two-part name to the design, while the Cloudsurfer 2 silhouette and men’s sizing context place it within On’s 2025 footwear offering.
