On Running Cloudmonster 3 | Sand Lime White | CloudTec® Phase

Maximum Cushion. Minimum Weight. Maximum Energy.

The On Running Cloudmonster 3 in Sand/Lime/White is the most cushioned and most visually dramatic shoe in On’s performance running lineup — a shoe that takes On’s signature CloudTec® Phase cushioning technology and amplifies it to its most extreme expression, delivering a midsole stack height that is the tallest and most cloud-like in the entire On catalog. The sand-toned engineered mesh upper, black On logo, and “ON RUNNING” lateral branding sit atop a white CloudTec® Phase midsole that is as visually striking as it is functionally exceptional — its oversized cloud pods visible from every angle, its lime green Speedboard® outsole providing the propulsive energy return that makes the Cloudmonster 3 as fast as it is comfortable. This is the shoe for runners who want maximum cushioning without sacrificing the lightweight, energetic ride that has made On one of the fastest-growing performance running brands in the world.

Product Highlights

• 🎨 Colorway: Sand/Cream Engineered Mesh Upper × Black On Logo & Lateral Branding × Black Laces × White CloudTec® Phase Midsole × Lime Green Speedboard® Outsole — the most energetic and most visually striking Cloudmonster 3 colorway
• 🕸️ CloudTec® Phase Midsole: On’s most advanced cushioning technology — a dramatically oversized array of hollow cloud pods that compress on impact and lock together at toe-off to deliver a smooth, rolling heel-to-toe transition. The Cloudmonster 3’s CloudTec® Phase midsole is the tallest and most cushioned in the On lineup, delivering a plush, cloud-like underfoot experience that absorbs impact without sacrificing the responsive, energetic feel that defines On’s running philosophy
• ⚡ Speedboard® Carbon Fiber Plate: On’s proprietary carbon fiber plate embedded within the midsole — storing energy during the compression phase and releasing it at toe-off for a propulsive, spring-like energy return that makes each stride more efficient. The lime green Speedboard® is visible through the outsole’s cloud pod structure, providing both a functional performance advantage and a distinctive visual detail
• 🧵 Sand Engineered Mesh Upper: Lightweight sand/cream engineered mesh upper — a breathable, flexible construction that wraps the foot in a sock-like fit while maintaining the airflow needed for long-distance comfort. The mesh’s neutral sand tone provides a warm, versatile base that pairs naturally with the white midsole and lime green outsole
• 🏷️ On Running Lateral Branding: “ON RUNNING” printed in bold black text along the lateral heel panel — a branding detail that makes the shoe’s identity immediately legible from the side, complementing the black On logo on the lateral midfoot
• 💨 Lightweight Construction: Despite its dramatically oversized midsole, the Cloudmonster 3 maintains the lightweight construction that defines On’s performance running philosophy — delivering maximum cushioning without the weight penalty that comparable stack-height shoes from other brands typically carry
• 🤝 Unisex Sizing: Available in unisex sizing — fits both men and women across a wide size range

About On Running

On Running is the Swiss performance running brand founded in 2010 by Olivier Bernhard, David Allemann, and Caspar Coppetti — one of the fastest-growing and most innovative running brands in the world. On’s founding insight — that running should feel like running on clouds — led to the development of CloudTec®, the brand’s signature cushioning technology that has since evolved through multiple generations and been adopted by elite athletes and everyday runners alike. The Cloudmonster 3 represents On’s most ambitious expression of the CloudTec® philosophy — maximum cushioning, maximum energy return, and the distinctive cloud-pod aesthetic that makes On shoes immediately recognizable from any angle.

Cloudmonster 3 vs Cloudmonster 2

The Cloudmonster 3 builds on the Cloudmonster 2’s already exceptional cushioning platform with an updated CloudTec® Phase midsole geometry, refined upper construction, and improved Speedboard® energy return. The result is a shoe that is more cushioned, more responsive, and more refined than its predecessor — the definitive expression of On’s maximum-cushion running philosophy.
