On Running Cloudboom Strike LS: Lightweight Power Meets Precision

The On Running Cloudboom Strike LS is built for serious runners who want to win. Designed for long-distance races, especially marathons, this shoe merges explosive propulsion with responsive cushioning in a lightweight build. It is ideal for competitive runners who need a fast, efficient, and aggressive racing shoe.

LightSpray™ Technology Details

The LightSpray™ upper uses a recyclable thermoplastic filament. A robot sprays over a foot-shaped mold, creating a seamless upper. Designers then fuse it to the midsole using heat, not glue. This advanced process avoids stitching and trims manufacturing to under three minutes per pair.
The upper weighs just 30 g and provides targeted support with breathability and zero distractions. It feels like a second skin and minimizes irritation during races.

Athletes like Hellen Obiri wore Cloudboom Strike LS prototypes to win the Boston Marathon and competed in the Paris Olympics. The shoe helped her avoid lace failures and maintain focus throughout

Dual-Layer Cushioning and Carbon Speedboard™

At the core of the Strike LS is a carbon-infused Speedboard™, which delivers a responsive push with every stride. This plate sits between two layers of Helion™ HF foam—a Pebax®-based compound engineered for maximum rebound and energy efficiency. The result? You get unmatched responsiveness during fast paces while maintaining cushioning underfoot.

Key Features

• Helion™ HF Foam: A Pebax® superfoam offering ultra-lightweight cushioning and incredible energy return for high-speed racing.

• Carbon Speedboard™: Provides a powerful toe-off and enhanced propulsion throughout your stride.
