Unisex On Running Cloudboom Strike 2

Engineered in collaboration with elite athletes to dominate the half and full marathon distance, this stands as On Running’s most aggressive racer yet.

This racer gets huge upgrade, featuring a highly propulsive Helion HF foam shaped in a CloudTec Sphere, an. innovative two-piece midsole construction. The midsole is designed to separate the forefoot and midfoot, allowing the foam to respond independently and multi-directionally to your stride pattern. The design offers excellent shock absorption, a smoother turnover of the legs, and an aggressive snappy toe-off. 

What to love: 

• A multi-directional, flexible CloudTec Sphere™ midsole for softer, smoother and more stable rides.
• On Running's most aggressive and responsive racer for 5K to marathon distances.
• An adaptable, lightweight breathable thin race ready upper.

MIDSOLE

• Carbon Speedboard®: A full-length carbon fiber plate embedded within the hyper foam to deliver rigid, aggressive leverage and snapping forward propulsion.
