On Running | Cloudboom Strike 2 | Unisex | Verdite/Aconite
The On Cloudboom Strike 2 is an elite carbon-plated marathon racing shoe engineered to help you run your fastest 26.2 miles. Building on the success of its marathon-winning predecessor, this next-generation super shoe is lighter, more efficient, and more propulsive, delivering the speed, comfort, and energy return competitive runners need on race day.
The dual-layer Helion™ HF midsole features an evolved superfoam that is 15% lighter while delivering greater resilience and energy return. A free-floating Bounceboard in the top layer preserves the soft, responsive feel that made the original Cloudboom Strike a standout, helping your legs stay fresher through the closing miles of a marathon.
Driving every stride forward is a redesigned full-length carbon fiber Speedboard®, now lighter and stiffer than before. Working in harmony with the responsive Helion HF foam, it creates explosive propulsion, smooth transitions, and exceptional running efficiency from the starting gun to the finish line.
New CloudTec® Sphere technology debuts in the forefoot, allowing the foam to expand in multiple directions for improved cushioning, comfort, and adaptability during long-distance racing. This innovative design helps reduce fatigue while maintaining a responsive, race-ready feel deep into your effort.
The ultra-light open leno weave upper maximizes breathability and moisture management to keep your feet cool in warm racing conditions. A redesigned waterfall heel construction with a lower-profile heel counter reduces pressure on the Achilles tendon while providing a secure, comfortable lockdown throughout the race.
Underfoot, an ultralight carbon nanotube rubber outsole delivers confident grip and improved slip resistance without adding unnecessary weight, helping you stay efficient on a variety of road surfaces.
Purpose-built for marathon racing, the On Cloudboom Strike 2 combines cutting-edge Helion™ HF superfoam, a full-length carbon fiber Speedboard®, CloudTec® Sphere technology, and an exceptionally lightweight design to deliver maximum propulsion, premium cushioning, and elite-level performance when every second counts.
