Fit Tip
If you're between sizes, we recommend choosing the larger size for a more comfortable fit.
Sizing may slightly vary depending on the brand or model.
Max out your comfort with these men's Cloudmonster Void trainers from On Running. In a triple Black colourway, these bold runners are built for both easy 5ks and long distances. The breathable mesh upper is made from part recycled materials and has synthetic overlays for support. A soft sockliner feels snug when you lace up, while the unique rocker delivers forward momentum underfoot. With a 6mm heel-to-toe drop, they're sat above a Helion superfoam and a Snappy Speedboard for energy return. With ultra-responsive CloudTec, they're finished up with oversized, tonal On Running branding.
