About this product
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 26.2, the On Cloudboom Strike 2 takes everything that made the original a marathon-winning shoe and improves it in every area that matters over the long haul.
The Cloudboom Strike 2 arrives at the starting line packing fifteen percent lighter foam, a stiffer carbon plate and a brand-new forefoot cushioning system. Evolved Helion HF compound delivers more resilience with less weight underfoot, while a lighter and stiffer full carbon fiber Speedboard drives more aggressive forward propulsion with every toe-off.
New CloudTec® Sphere technology in the forefoot allows multi-directional foam expansion for enhanced comfort and feel during the miles where cushioning needs to work hardest. For your final push, a free-floating bounceboard in the top midsole layer preserves the soft yet responsive sensation that made the first generation so celebrated — now refined and elevated for your next race.
Details:
- Upper: A new open leno weave construction is super-breathable and highly adaptive, evaporating moisture and heat to keep your feet comfortable in warm racing conditions. A lower heel counter with softer edges thanks to a waterfall construction increases heel comfort and reduces pressure on the Achilles tendon. Eliminating one of the most common sources of discomfort that shows up late in a marathon.
- Midsole: A dual-layer Helion HF setup pairs a free-floating bounceboard in the top layer with an updated foam in the bottom layer that is lighter and more resilient than before. New CloudTec® Sphere technology in the forefoot allows multi-directional foam expansion for better comfort and feel across long efforts. 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.
