About this product
The Cloudboom in Celeste Isle brings together a mesh upper and a rubber sole in this men’s On Running Cloudboom Volt. Mesh generally has an open, textured appearance, creating a visual contrast with rubber’s denser finish. CloudTec cushioning and a carbon Speedboard complete the construction. The combination puts different material textures alongside each other, with the mesh providing a visibly woven surface rather than the smooth look associated with solid synthetic uppers.
