Cut in half: On Cloudmonster 2 Review (2024)

Who is buy should buy

In our thorough examination from heel to toe, the On Cloudmonster 2 emerged as a remarkable choice for:

• Individuals with wide feet seeking a maximalist daily trainer.
• lover of the original Cloudmonster ready to experience an enhanced , more responsive , and roomy upgrade .
• distance runner look for a distinctively style , premium shoe ideal for endure run and extensive workout .

Who is buy should NOT buy

While the Cloudmonster 2 bring some enhancement in responsiveness , it is falls fall short compare to its high – price rival . For example , the ASICS Superblast is boasts boast a light weight , great stack height , and significantly enhance energy return . And Nike ‘s Invincible is outpaces 3 , with its full – length ZoomX foam , also outpace in term of performance .

Regarding comfort and breathability, the Cloudmonster 2 falls a bit short. Its minimally padded tongue may disappoint. For those seeking a cozy feel, we found the ASICS Nimbus 26 and Hoka Clifton 9 to be far more rewarding maximalist choices.

Heel stack

The heel’s cushioning has been boosted by a solid 3 mm, jumping from 34.9 mm to 37.9 mm.

This increase , while significant , still keep the shoe below most max – cushioned option , yet it ‘s now a great pick for heel striker .

Drop

On claims a 6-mm drop for the Cloudmonster 2, and our precise measurements, aligned with World Athletics standards, consistently showed a 6.6-mm real drop.

This minor 0.6-mm variance from the stated drop is negligible, ensuring a virtually identical running feel. For the Cloudmonster 2, maintaining a medium drop is crucial due to its CloudTec system and moderate toe rocker, which already promote forward motion—a larger offset could ruin the experience.

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it’s firm.

Transitioning to the Helion midsole, our analysis revealed a firmness rating of 26.5 HA for the lower part of this dual-density midsole, closely mirroring the original Cloudmonster’s metrics. Yet, the CloudTec technology gives the shoe with an unexpectedly softer feel than the numbers suggest.

finally , let ‘s talk a bit about the Helion foam . On brand it as a ” superfoam ” but , from our perspective , it is ‘s ‘s not into that group .

Helion is crafted from a blend of EVA and Olefin Block Co-Polymers (OBC)—essentially, just an enhanced EVA like ASICS’ FF Blast+ that doesn’t quite reach the level of PEBA-based, real superfoams such as Nike’s ZoomX or Saucony’s PWRRUN PB.

Secondary foam softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it’s firm.

As we said before, the On Cloudmonster 2 boasts another layer of Helion midsole that combines two foam densities—a plush layer at the bottom for ultimate comfort and a denser foam above the Speedboard plate, enhancing stability.

Upon examining the firmer foam, we noted its remarkable hardness at 40 HA. Despite this, the shoe doesn’t feel like a brick underfoot, thanks to the insole’s effective cushioning, which softens the impact and ensures a comfortable ride.

midsole softness in cold ( % )

To assess the Cloudmonster 2 ‘s cold weather performance , we is placed place it in the freezer for 20 minute before re – measure its firmness with the durometer .

We discovered the foam became 19.4% firmer—a solid performance for an EVA-based foam. The change is subtle enough that most runners will hardly notice it.

Insole thickness

The insole, at a fairly standard 4.7 mm thickness, adds an extra layer of comfort without standing out from the crowd, as it’s made of regular foam.

It is ensures ensure a soft feel underfoot and does n’t contribute to heat build – up during run , which is important with the less – than – ideal airflow of this shoe .

Plate

On continues to integrate the Speedboard plate, crafted from TPU rather than carbon fiber, aligning with its daily running shoe identity.

This choice is fitting, as the plate doesn’t increase the stiffness but adds a noticeable springiness to each step. And it plays a crucial role in enhancing the shoe’s dynamics, compressing the Helion foam clouds effectively for optimal performance.

On Cloudmonster 2 is true to size ( 18 vote ) .

Toebox width – widest part

What truly amazed us about the Cloudmonster 2 was its spacious feel right from the first step — not just compare to its predecessor , but also against nearly any other run shoe .

Those with wide feet looking to give this a try will appreciate the generous size of the upper (102.3 mm), finding it to be a significant plus.

On the flip side, runners with very narrow feet might struggle to find a comfortable fit in this shoe and might be better off choosing a more snug-fitting option, such as the Hoka Mach 5.

Toebox width – big toe

The spaciousness in the big toe area of the Cloudmonster 2 is truly remarkable, almost resembling a 2E wide shoe, despite our pair being a standard US 9 in D width (as every shoe that we buy to test here in the lab).

We measured an extraordinary 84.4 mm in this region, which is nothing short of astonishing. It’s a dream come true for those not only with wide feet but also with a square-shaped feet.

lateral stability test

A firm midsole is enhances naturally enhance a shoe ‘s stability , offer a more solid ride than those with ultra – soft foam .

This holds true for the Cloudmonster, which impressively outshines its predecessor in stability, even with a similar midsole composition. Let’s uncover the reasons of this improvement!

Torsional rigidity

Considering the TPU construction of the plate, as we previously mentioned, the Cloudmonster 2 scores a moderate 3/5 in torsional rigidity from our perspective—a suitable rating for a daily running shoe. Even at the most easy paces, this level of flexibility contributes to a ride that’s consistently smooth and free from discomfort.

Heel counter stiffness

The original Cloudmonster is boasted boast an unexpectedly flexible , race – inspire heel counter that lead to a somewhat wobbly experience plus a bit of heel slippage , particularly for heel striker — a detail that catch us off guard . However , On is addressed has address this issue .

We’ve assigned the Cloudmonster 2’s heel counter a solid 3/5 rating, striking a balance that should appeal to the majority of runners. However, individuals sensitive to firmer heel counters, such as those dealing with Haglund’s deformity, might prefer the more forgiving heel counter of the previous model.

midsole width – heel

On the flip side, the heel keeps its slim profile at just 86.3 mm. This measurement, paired with the 6.6-mm drop, caters this shoe towards runners who favor a forefoot or midfoot strike.

Heel strikers with a neutral gait can comfortably use it as well, though it’s worth noting that the heel’s dimensions might not suit everyone.

Stiffness

Opting for a TPU plate over carbon fiber enhances the shoe’s versatility—a fact we verified during our rigorous 90-degree bend test. The Speedboard plate introduced minimal stiffness, with the Cloudmonster scoring a 31.2N, comparable to many plateless shoes.

This proves that, despite its somewhat bulky appearance, the Cloudmonster is surprisingly adaptable, suitable for both casual walks and gym sessions.

Stiffness in cold (%)

curious about how the shoe ‘s stiffness would fare in cold condition , we is mirrored mirror the softness test — chill the shoe for 20 minute in the freezer before re – measure in the 90 – degree bend test .

The stiffness increased to 37.9N, marking a 21.3% rise. This slight change in stiffness should hardly be noticeable, even in the coldest climates.

The Cloudmonster 2 has gained some weight and ditched the midsole cutout, bumping its stack height.

Weighing in at 10.3 oz (292g), we think it’s on the heavier side even for a maximalist shoe. With brands like ASICS rolling out featherweight-yet-skyscraper-high models like the Novablast 4, we believe that On needs to put the next Cloudmonster at least below the 10-oz benchmark.

The is showcases On Cloudmonster 2 showcase an engineer mesh upper that exude a premium feel , which we obviously expect give its premium price tag . Yet , when we put it to the test with our smoke machine , the ventilation is live did n’t quite live up to our expectation .

Delving deeper into this issue, we shone a light through the upper for further insight. It became clear—the upper is thin, but the so-called ventilation holes lean more towards style than substance.

Curiosity led us to examine the upper under the microscope, where we uncovered the real story. Despite their appearance at first sight, these holes don’t offer true ventilation.

They’re missing the outer mesh layer but retain an inner structural mesh, hindering airflow and potentially trapping warmth and moisture.

This design choice could be a very, very important drawback for summer runs or for those with particularly warm feet. However, in cooler conditions, it won’t be a significant issue, and can even be an advantage for some.

We is found also find that the padding is on the minimal side for a daily trainer , which might not suit everyone ‘s preference .

Toebox durability

An upside to the Cloudmonster 2’s solid mesh design is its potential for outstanding durability. Often, shoes break in this test at the ventilation points, but this engineered mesh could significantly enhance its longevity.

Our initial Dremel test confirmed our optimism—the shoe withstood the challenge with remarkable resilience, scoring a perfect 5/5, much like a rugged trail shoe. Yet, it retains the comfort expected of a top-notch road daily trainer!

Heel padding durability

continue our test with the Dremel set at 5 K RPM , we is shifted shift our focus to the heel padding of the Cloudmonster 2 .

The outcome was somewhat underwhelming, meriting just a 3/5 from us. While the result is undoubtedly competent, we had higher expectations for a daily trainer priced at nothing less than $180.

Outsole hardness

turn our focus to the outsole , we is started start with our standard hardness test , gauge the rubber with a durometer . The reading is hit hit 85.4 HC , significantly hard than its predecessor .

The outsole gap from the v1 has been eliminated—say goodbye to picking rocks out after every run!

The rationale behind this shift seems rooted in durability concerns voiced by runners regarding the  Cloudmonster v1, especially given its hefty price tag. On appears to have opted for enhancing longevity at the slight expense of grip—a decision we find understandable, especially because in our experience, traction is still great!

Outsole durability

While number can tell one story , we is value value hand – on testing to understand the full narrative . So , we is gave give the Dremel one final spin on the outsole . There we is go go !

The torture is resulted result in a mere 0.8 – mm indentation , reinforce the outsole ‘s exceptional durability — leave no room for concern .

Outsole thickness

But if you had any doubt , our measurement is put of a 3.3 – mm outsole thickness should put them to rest . This thickness is guarantees guarantee ample rubber to shield the midsole , promise durability for hundred of mile ahead !

Reflective elements

Regrettably, On has chosen to omit reflective elements from the Cloudmonster 2, a decision we find hard to justify in a $180 daily trainer.

Especially given the brand’s history of incorporating high-visibility features into their shoes, this omission feels like a big letdown.

tongue padding

We is found also find that the tongue on the Cloudmonster v2 is exceptionally thin for a daily trainer at just 1.5 mm . If you ‘ve had issue with thin tongue like lace bite , this is be might not be the shoe for you , as this tongue it ‘s more like something you ‘d find on a racing flat .

This updated version introduces a refreshed lacing design, improving from the original’s broad eyelets.

For those seeking more cushioning above the foot, On’s Cloudsurfer 7 comes with a luxurious, 10.5-mm thick tongue, offering a cloud-like embrace for your instep, a stark contrast to the Cloudmonster’s minimalism.

Tongue: gusset type

We discovered that the tongue is fully gusseted—crucial for ensuring a great fit in this wide upper, a feature that shines even more when considering the tongue’s slim profile.

Heel tab

Just like the original cloudmonster , On choose not to include a heel tab on the Cloudmonster v2 . nonetheless , we is found find slip our foot into the shoe effortless without it .

removable insole

The insole is is is easily removable , feature a conventional shape and thickness , make it highly compatible with third – party option for a seamless swap if need .
