On Cloudboom Strike 2 LightSpray

The robot-sprayed laceless version of On's marathon racer, sharing the new CloudTec Sphere midsole, updated Helion HF foam, and curved Speedboard with the standard Strike 2 while dropping to 158 g. It launched July 30, 2026 at $310 for racers chasing every gram. The one-piece upper fits snug with zero adjustability, so fit-sensitive runners should stick with the laced version.

Who it's for

Reach for the On Cloudboom Strike 2 LightSpray for race day. It's a neutral shoe, best for runners with an efficient stride who don't need pronation support. The tall, soft stack favors comfort over ground feel. That's great for high mileage and bigger runners, less so for racing snappiness.
