On Cloudboom Strike 2 Lightspray

Outfitter's Tip: this is a UNISEX-sized shoe. Men's sizes are shown — women should order 1.5 sizes below their standard running shoe size. For example: for a women's size 9.5 shoe, order a size 8.

Built to help you chase your fastest full or half marathon, the On LightSpray Cloudboom Strike 2 takes everything that made the original a marathon-winning shoe and pushes it further with the addition of On's most innovative upper technology yet. LightSpray™ construction begins with a single 1.5 km yarn woven by robot in just three minutes into a seamless, second-skin upper that eliminates waste, reduces weight to just 158 g and delivers a fit that adapts naturally to your foot from the starting line to the finish.

The CloudTec Sphere™ cushioning system is the other meaningful step forward in the Cloudboom Strike 2. Thin gaps between the forefoot and midfoot allow the foam to move more freely, adapting and flexing in multiple directions for a smoother, more responsive feel at race pace. Lighter, more resilient Helion HF hyper foam delivers strong energy return underfoot, and a carbon Speedboard channels that energy forward with aggressive, efficient propulsion across the full marathon distance.

Details:

• Upper: A robot-woven LightSpray™ construction creates a seamless, ultralight upper from a single continuous yarn with no stitching, no seams and no unnecessary weight. The result is a second-skin fit that adapts to every foot shape and keeps your feet comfortable through warm racing conditions. The Elite Run Sock High Hyper comes included with the shoes, engineered specifically to work in perfectly with the LightSpray™ upper for an unmatched fit experience on race day.
• Midsole: CloudTec Sphere™ cushioning features thin gaps between the forefoot and midfoot that allow foam to expand and flex in multiple directions for a smoother, more responsive ride at speed. Lighter and more resilient Helion HF hyper foam delivers strong energy return throughout, keeping legs feeling fresher deeper into the race. A full carbon fiber Speedboard — lighter and stiffer than the previous version — channels energy forward with aggressive, efficient propulsion from start to finish.
• Outsole: Carbon nanotube rubber combines an ultralight construction with improved slip resistance for confident traction on the race course.
