The On Cloudboom Strike 2 is On's most advanced marathon racing shoe yet, and it's a full evolution of the franchise. The headline is CloudTec Sphere: a redesigned segmented forefoot with thin gaps that let the foam flex and expand in multiple directions for a smoother, more responsive feel at race pace. Underneath, a lighter, more resilient Helion HF foam and a carbon Speedboard work together to channel energy forward with efficient, aggressive propulsion. The payoff is a 6.7 oz racer engineered to keep your legs fresh deep into a marathon — the same Cloudboom franchise Helen Obiri has been running into the record books. And at $250, it delivers elite super-shoe performance at one of the best prices in the category.

What we're geeking out about:

CloudTec Sphere — the segmented forefoot flexes multi-directionally for a smoother, more responsive feel at race pace
6.7 oz on a full carbon Speedboard — featherweight for a shoe built to go the full 26.2
