On Cloudboom Strike

RUN (powered by Outside) praises the On Cloudboom Strike as a thoughtful evolution of the carbon‑plated super shoe formula, highlighting On’s bold removal of the strobel and sockliner in favor of a thicker, higher‑quality Helium Hyperfoam “bounceboard” that yields noticeably more cushioning and lively rebound. The reviewer is enthusiastic about the plush, trampoline‑like ride, light weight (about 7.3 oz), and confident midfoot-to-rearfoot feel at marathon and threshold paces, noting it also handles faster efforts and could double as a workout shoe. Criticisms are measured: the high, narrow stack can feel tipsy and unstable at slower paces and may not suit beginners, and the shoe favors mid/rearfoot striking over toe-off drive. Overall the tone is positive and appreciative of On’s engineering tradeoffs, recommending the Cloudboom Strike for advanced and intermediate runners seeking a highly cushioned, race‑focused marathon option.

Carlos Sánchez from RunRepeat praises the On Cloudboom Strike as On’s strongest attempt at a super shoe, highlighting world-class energy return, excellent shock absorption, and a surprisingly roomier, breathable upper that makes it marathon-ready for forefoot and midfoot strikers. He gives detailed lab metrics (72.1% forefoot energy return, 39.5 mm listed stack, 201 g weight, flex and durometer figures) and applauds the innovative single-slab Pebax insole/midsole and extensive rubber coverage for grip. Criticisms are clear: limited stability, minimal heel padding that can cause slippage for heel strikers, marginal durability in the thin upper, and a premium price. Sánchez compares it to top competitors (Saucony, Nike, ASICS), recommends it chiefly for forefoot racers across 5K–marathon distances, and advises heel strikers or those needing extra stability to choose other models. Overall tone is confident and positively enthusiastic but measured about trade-offs.

Brandon Law from Running Shoes Guru praises the On Cloudboom Strike as an exciting, bouncy long‑distance racer that delivers noticeably softer cushioning and superior energy return compared with the Cloudboom Echo 3. He celebrates its engaging forefoot-centric ride, secure heel lockdown, and improved outsole durability, noting the innovative thick removable insole that puts your foot closer to the Helion HF foam. However, Law tempers enthusiasm with measured criticism: the shoe runs half a size large, has excessively long laces, offers poor wet‑surface grip, and lacks a prominent forefoot rocker — making transitions less efficient and tiring the lower legs on hard efforts. He recommends the Strike for fore-/midfoot strikers in 5K–half marathon races and speedwork, but not for marathoners, heel strikers, or anyone needing a highly rockered, marathon‑efficient super shoe.

RTINGS praises the On Cloudboom Strike as a lightweight, well-cushioned carbon-plated racer that prioritizes long-distance comfort and leg preservation. The review is upbeat about the Helion HF foam, thick removable “bounceboard” insole, and true-to-size fit, calling the shoe especially well-suited to marathons where reduced fatigue matters. At the same time the tone is measured: testers note it isn’t the bounciest or most stable super shoe, and the soft forefoot foam can blunt aggressive toe-offs and quick transitions for 5K/10K specialists. Comparisons to rivals (Nike, adidas, New Balance, Saucony, PUMA) underline that the Strike trades some snap and lateral firmness for superior underfoot protection and a lighter overall package. Overall the review reads positively but pragmatic — recommending the Strike for runners seeking a cushioned, marathon-focused racer rather than a hyper-responsive, short-distance weapon.

Erin Bailey, an NYC-based runner featured in Runner’s World US, praises the On Cloudboom Strike as a sleek, lightweight race shoe that blends responsive Helion HF cushioning and a spoon-shaped Speedboard for energetic toe-offs. She emphasizes true-to-size fit and a roomy toe box, calling the upper highly breathable and the tongue secure; overall she felt locked-in stability and appreciated how the shoe balances cushioning with a fast, nimble ride. Minor issues include initial Achilles rubbing when laced very tight, and only moderate grip on wet downhills, but traction on flats was strong. Tested over demo runs and a full 5K, Bailey’s first impressions lean enthusiastic and confident—she calls it a “strong, trustworthy” racing option she’d use for longer efforts, while noting a couple of fit and traction caveats to watch.

RoadTrailRun’s Michael Ellenberger praises the On Cloudboom Strike as a lively, marathon-ready supershoe that finally brings On into the top tier of long-distance racers. He’s enthusiastic about the Helion HF “drop-in” midsole that layers energetic foam directly above the carbon plate—yielding exceptional bounce, lightness, and a propulsive ride at tempo and race paces—while noting the outsole is adequate but not exceptional. Criticisms focus on a narrow midfoot and slight rear/midfoot instability (a “midfoot wobble”) that may bother wider-footed runners or at slower paces, plus a finicky entry and noticeable squeak indoors. Michael backs his view with measured comparisons to ASICS, Nike, Adidas, and Alphafly models, race-test experience (marathon and half-marathon PRs), weights, and stack specs, concluding the Strike is a fun, high-performing choice for racers who try them on for fit and prefer a very soft, bouncy feel.

Doctors of Running praises the On Cloudboom Strike as a lively, highly propulsive carbon‑plated race shoe that delivers exceptional forefoot bounce thanks to a novel “Bounceboard” sockliner and very soft Helion HF foam. Reviewers (David Salas, Nathan Brown, Andrea Myers) consistently highlight its energetic, responsive ride—especially at 5K–10K and up to half‑marathon paces—and compare it favorably to Alphafly and Metaspeed Edge models. Criticisms center on a slightly narrow/unstable rearfoot, variable heel fit, a stiff upper that takes breaking in, and limited compatibility with aftermarket insoles or orthotics. Testers ran interval workouts, races, and longer runs and graded the shoe highly for performance and value while noting it’s best for midfoot‑leaning, stability‑indifferent runners who prioritize pop over long‑distance comfort. Overall tone: enthusiastic and impressed but measured, recommending the Strike with caveats about heel fit and stability.

Thomas Neuberger from Believe in the Run praises the On Cloudboom Strike as On’s best race-day shoe to date, calling it light, fun, and explosively responsive with a unique drop-in Helion HF midsole and carbon plate. He highlights excellent forefoot cushioning, quick turnover, and a breathable, minimal upper that simplifies lacing and keeps weight down (7.8 oz for a US M10). Notable negatives include inconsistent sizing across samples and a stiff heel collar that caused Achilles irritation in one tester — practical caveats that temper the enthusiasm. He compares its foam to Adidas Lightstrike Pro and positions the Strike against Metaspeed and Vaporfly 3, while noting the $280 price premium. Overall the tone is strongly positive but measured by real-world fit and comfort concerns.
