Running shoes On CLOUDMONSTER 2

The On Cloudmonster 2 is a maximum-cushioning daily trainer designed for road running and long-distance efforts. It suits neutral runners looking for a protective, responsive platform that handles easy runs, long miles, and faster-paced training.

The midsole uses dual-density Helion foam, with softer foam in the forefoot and a firmer base underfoot, creating a ride that feels surprisingly firm for a max-stack shoe while remaining protective and resilient. The Cloudmonster 2 features the largest CloudTec pods On has produced, paired with a nylon Speedboard nestled between the foam layers to add propulsion without excessive stiffness. The forefoot rocker geometry transitions smoothly across a range of paces, from easy efforts to uptempo work, though the firm foam character means less plush cushioning and bounce compared to softer max-cushioned trainers.

The engineered mesh upper provides a higher-volume fit throughout, particularly in the midfoot and forefoot, with a gusseted tongue and elastic eyelets in the lacing system. The heel counter offers moderate padding and flexibility, while the overall construction accommodates wider feet and benefits midfoot or forefoot strikers. Runners typically need to snug down the laces for secure lockdown given the roomy interior.

The outsole uses a pod-based CloudTec system with widely spaced rubber segments that grip road surfaces reliably and can handle occasional mild trail crossings. The On Cloudmonster 2 sits on a wide, stable platform with sidewalls that provide mild guidance while maintaining the shoe's neutral classification.
