Asics Metaspeed Sky Paris vs On Cloudboom Strike:
Which to Choose

October 4, 2026

Verdict

These are peers, not opposites — both are elite neutral super shoes that will race 10K to marathon at a high level, so neither is a mistake. It comes down to weight and distance: pick the Metaspeed Sky Paris for its exceptional lightness and marathon tuning, and the Cloudboom Strike for its firmer, more aggressive rocker and half-marathon sweet spot. If you can, run in both and let fit and toe-off feel make the final call.

Who Should Choose Each Shoe

Choose

Asics Metaspeed Sky Paris

Choose the Metaspeed Sky Paris if your goal race is the marathon and you want the lightest possible shoe under you for the final hard miles — it's built to disappear on the foot and reward a committed forefoot-to-midfoot strike held at sustained sub-3:10 min/km effort. It's the better pick for runners who value featherweight feel and a lively, flowing ride over a firmer, more aggressive push, and who are already comfortable managing a narrow, low-stability racing platform.

Choose

On Cloudboom Strike

Choose the Cloudboom Strike if the half marathon is your target and you like a firmer, more overtly propulsive toe-off that drives you through crisp transitions at genuinely fast pace. Its slightly lower 4mm drop and marginally taller forefoot suit runners who want a touch more foam under the ball of the foot and a rocker that actively steers each stride, and who don't mind carrying a bit more shoe in exchange for that planted, driving feel.

Head-to-Head

On paper these two are strikingly close: both ride on roughly a 39.5mm heel stack that sneaks just under the 40mm racing limit, both use a resilient PEBA superfoam (Asics' FF Turbo Plus, On's Helion HF) over a full-length carbon plate, both are rated high-but-not-maximal on cushioning and very high on responsiveness, and both are genuinely low on stability — tall, narrow race platforms that feel tippy at a jog and only settle once you commit to pace. The clearest hard difference is weight: the Metaspeed Sky Paris is one of the lightest marathon racers made, landing around 178g (about 6.3 oz) in a men's US 9, while the Cloudboom Strike is noticeably more substantial at roughly 219g (7.72 oz). That ~40g gap is felt late in a race, and it's the single biggest reason to favor the Asics if you prize raw lightness. Geometry differs subtly too: the Sky Paris runs a 5mm drop with a 34.5mm forefoot, while the Cloudboom Strike sits at a 4mm drop with a slightly taller 35.5mm forefoot, giving the On a touch more under the ball of the foot and a marginally more forefoot-friendly feel. In ride character, both rely on a rocker to roll you forward, but the Sky Paris leans on its ultralight foam-and-plate snap for a lively, flowing turnover, whereas the Cloudboom Strike's rocker feels more insistently propulsive and firm through toe-off. Use-case tuning is the other tiebreaker: both cover 10K through the marathon, but the Sky Paris is dialed in with the marathon as its clearest sweet spot (optimal around 3:00–3:35 min/km), while the Cloudboom Strike peaks at the half marathon (optimal around 3:00–3:20 min/km) and asks for a slightly faster effort to extract its full return.
