Cloudboom Strike
A carbon-plated shoe for half-marathon and marathon racing. Its Helion HF cushioning delivers a lively ride with a balanced feel, especially for runners who land toward the front of the foot.

The shoe at a glance.
The Cloudboom Strike brings a lively, balanced ride to half-marathon and marathon racing through Helion HF cushioning and a carbon Speedboard. It is particularly appealing for runners who land farther forward and want a secure racing shoe with some usable space around the toes. The narrow heel provides limited stability, while the light upper puts race-day performance ahead of everyday durability. Length is generally true to size, but checking the secure midfoot hold alongside heel confidence is sensible before a long event.

Cushioning and ride
Independent testing favors forefoot landings in this highly cushioned racer. Its roomier fit may help some feet, but rearfoot security and stability still need checking.
Our editorial ride category: balanced.
