Product Overview

The On Women's Cloudmonster 1 is the original that rewrote the rules — On's first true max-cushioned running shoe, now celebrated as much for its lifestyle credibility as its performance on the road. Built on Helion™ superfoam and the iconic CloudTec® cushioning system, the Cloudmonster 1 delivers a responsive, forward-rolling ride with a silhouette that turns heads whether you're logging miles or running errands. Bold, versatile, and proven — this is the shoe that started the Cloudmonster franchise.

Key Features:

• Helion™ Superfoam Midsole: On's signature multi-compound foam delivers a uniquely balanced ride — cushioned enough to protect on long runs, responsive enough to feel light and quick underfoot.
• CloudTec® Cushioning System: Oversized, independent Cloud pods absorb impact on landing and spring back at toe-off, giving the Cloudmonster 1 its distinctive, energetic feel that set it apart from every other max-cushioned shoe at launch.
• Speedboard® Technology: A flexible nylon blend plate embedded in the midsole stores energy during the loading phase and snaps back at push-off for a propulsive, efficient stride.
• Dramatic Rocker Geometry: The curved sole shape encourages a smooth heel-to-toe transition and a natural forward roll — making the shoe feel effortless at easy paces and surprisingly capable when you pick it up.
• Recycled Polyester Mesh Upper: Built from 100% recycled materials, the lightweight mesh upper offers excellent breathability, a clean premium look, and a secure, seamless fit that works all day.
• Fully Gusseted Tongue: Attached on both sides to stay put throughout a run — no mid-run adjustments needed, no pressure points over long distances.
• Iconic Lifestyle Silhouette: The Cloudmonster 1's bold, chunky profile has become one of the most recognizable in running — equally at home on the road and off it.
