On Men's Cloudmonster 3 Hyper "Glacier/Black"

The On Cloudmonster 3 Hyper is a high-performance super trainer built for runners logging big miles and fast workouts. Designed by Swiss running brand On, it blends max cushioning with energetic responsiveness to handle long runs, tempo sessions and demanding weekly mileage.

At the core of the shoe is CloudTec® cushioning, engineered to deliver a highly responsive and energetic ride. Paired with Helion™ HF hyper foam, the midsole provides exceptional energy return while maintaining a lightweight feel. A durable bottom layer of Helion™ foam adds resilience for consistent performance over long distances.

Unlike many super trainers, the Cloudmonster 3 Hyper runs without a plate, helping reduce impact and maintain a smoother, more natural ride that keeps legs feeling fresher during extended training blocks.

Up top, a strong, breathable upper balances structure with ventilation, while a re-engineered heel construction enhances comfort during multi-hour runs. Underfoot, the enhanced rocker geometry promotes smooth transitions and powerful push-offs, helping maintain rhythm when the pace increases.

Combining high-stack cushioning with energetic rebound, the Cloudmonster 3 Hyper is designed for runners who want a fast, comfortable trainer capable of handling everything from daily miles to tempo efforts.
