LightSpray Cloudboom Strike

Key Features & Technology

• LightSpray™ Upper: This is the defining feature of the shoe. A robotic arm spins a single 1.5km filament directly onto the midsole to create a seamless, lace-free, one-piece upper. Weighing only about 30g, it fits like a "second skin," offering breathability and precision without the pressure points or weight associated with traditional stitched uppers.

• Helion™ HF Hyper Foam: The midsole features two layers of premium, ultra-responsive Helion™ HF hyper foam (made with over 40% bio-based materials). This foam provides exceptional energy return and impact protection, keeping legs feeling fresher during long-distance efforts.

• Carbon Fiber Speedboard®: A curved, spoon-shaped carbon fiber plate is embedded between the layers of foam. This acts like a spring, absorbing energy on impact and transferring it into powerful forward propulsion for each stride.

• Efficient Geometry: The shoe is built with a stack height optimized for World Athletics regulations, providing a max-cushioned feel that remains remarkably lightweight and agile.

Performance Profile

• Best For: Road racing, marathons, half-marathons, and high-speed training sessions.

• Feel: Responsive and fast, with a snug, secure fit. It is designed for runners who want a direct, "second-skin" connection to the road.

• Fit Note: These are typically unisex-sized. Because the precision-engineered upper has less stretch than traditional mesh, some runners may prefer to try them on in-store for the best fit, particularly if you typically require a wider shoe.
