On Cloudboom Volt White Black Carbon Marathon Racer

Carbon racing made more accessible. The On Cloudboom Volt slots a full-length carbon-fibre Speedboard into dual-layer Helion HF foam, weighing just 210 g and sitting well below the price of the Cloudboom Strike above it.

How it rides

On deliberately tuned the Volt's PEBA-based foam firmer than the Strike's, so it feels steadier and more planted, which makes it easier to run long in. Expect a firm, propulsive ride rather than a soft bounce. It is aimed at marathon and half marathon race day, and is also usable for long and easy runs.

• Full-length carbon-fibre Speedboard
• Dual-layer Helion HF (PEBA) foam, tuned firmer
• Lightweight mesh upper with toe guard
• Sits alongside the Cloudboom Strike as the steadier option
• 5 mm drop (men's), approx. 210 g (men's US 9)
