    ON CloudStratus - Reach for the skies, but the clouds are the limit

    More photos

    On Running. I love a company that is not afraid to try new and different things. Their shoes have always intrigued me with their unique designs and fancy looks. However, It has been a brand that has not impressed me, and yet I try their new offerings in hopes that they get it right.

    The On CloudStratus is a huge improvement from the company, but On Running must take some serious considerations from consumer feedback to keep up with the other running brands.

     

    Weight: 305grams/10.76oz           Heel-to-toe Drop: 8mm          Category: Stability

    Upper

    A soft and breathable engineered mesh upper is used. There is an orange mesh layer in the toe box to help with upper durability while maintaining its breathable nature.

    The toe box is reinforced, which helps maintain the structure of the shoe.

     

     

    An additional reinforced mesh layer is used to wrap the medial and lateral side of the foot like a burrito. This helps with securing the foot by providing a comfortable yet snug fit.

    Thoughts

    Finally! On got it right this time. I absolutely LOVE the upper! It has one of the best uppers that I’ve tried on to date. The toe box is not shallow, nor is it narrow like the rest of the On line-up.

    I really enjoyed the form-fitting upper and had no need for any breaking in whatsoever. The excessive cushion in the interior of the shoes that exist in most daily trainers is not found here.

    On manages to get the amount of padding just right. The shoe remained well ventilated and dissipated heat well even at temperatures of 32 degrees Celsius. This is the first time that I have zero complaints on the upper of a shoe. Just perfect!

     

    Lacing

    A star-lacing configuration is utilized. I did not find any difference in the fit other than the fact that it looked unique. I am unable to tell if it really helps, but it seems gimmicky to me.

     

     

    Three additional lace holes are available if the user wants a customized and more locked down fit. Personally, I found the standard lacing enough for lockdown.

     

    Heel cup & ankle collar

    The ankle collar has just the right amount of padding. This made the shoe feel plush and comfortable without feeling like too much shoe.

     

     

    An external heel cup is used in the shoe. I noticed that the heel cup is higher on the medial side.

    This is intentionally designed to increase stability. It was not noticeable and did not affect the comfort of the shoe.

    Tongue

    The tongue is well padded and prevents any lacing pressure.

     

     

    I like that it's attached to the upper, which prevents any side to side slippage.

     

    Insole

    The insole is ribbed on the medial side where the arch is. This is intentionally designed to allow consumers to be aware of their running form when it begins to be sloppy at the later stages of a run.

    However, this was designed with the neutral runner in mind. As to how it works, the ribbed area will be felt if the arch of the foot encounters it.

     

     

    At the later stages of a run, when form starts to get sloppy, overpronation will occur more often, and the runner will then be able to feel the ribbed portion. This acts as feedback for the runner to focus on his form.

    I found the design to be interesting but sadly unhelpful as I felt the ribbed portion the moment I put my feet into the shoe. It may work for others, but not for me.

    Sizing & fit

    The CloudStratus fits true to size. It accommodates my wide foot well.

    I had problems with almost all the shoes from the On line up, but On seemed to have widened the toe box in this one. The improved fit allowed for my toes to splay without any pressure points.

     

    Midsole technology & the ride

    Cloudtec Elements

    An additional layer of Cloudtec Elements that run from the heel to the midfoot. The Cloudtec elements are designed to compress upon impact to provide for a softer landing.

     

     

    Helion Foam

    ‘Helion’ is a brand-new midsole compound that claims to be lighter, temperature resistant, durable, and bouncier than any previous cushioning setup On has used in the past.

     

     

    Speedboard

    A thin plastic board that runs just below the insole to facilitate a more directed, snappy, and responsive ride.

     

    Thoughts

    The shoe rides FIRM. I expected a bouncy and plush ride from the new ‘Helion’ midsole and added a layer of cloud elements.

    With incredible new midsole technology such as Nike React and ZoomX, New Balance FuelCell, and Skechers Hyperburst, I was deeply excited about whether ‘Helion’ would deliver a similarly enjoyable experience.

    I was sorely disappointed. Throwback maybe 5 years, and this would have been one of the best shoes in the market. Its time for On Running to move on with the times and keep up with the competition.

    The midsole probably the softest offering for On Running but is still considerably firm. Even Mizuno, known for its plastic wave plates and firm midsoles, has ditched their wave plate in their newest offering: ‘Sky Waveknit 3’ and added a new polyurethane cushioning.

     

     

    To the touch, the Helion foam hardly had any give. Other foams like Saucony’s Everun, and the few abovementioned foams all had a certain level of ‘squishy’ characteristics when I pressed them. I thought, ‘Maybe the Cloudtec elements will allow for a softer ride while running in them.’

    On foot, the CloudStratus felt firm but very stable and protective. However, the CloudTec elements provided a little effect of softening the ride.

    The ride seemed to soften a little after roughly 30km in them but far from ‘Running on Clouds.’ If any representative of On Running is reading this review, please, soften the midsole. I am unable to use the shoes on recovery runs as they are just too firm.

    The next issue I found was with the Speedboard. The plastic speedboard is placed too close to the foot, with only an insole separating it.

    I used the same analogy in previous reviews of On shoes: Placing a bed on top of the wooden plank is softer than if it were the other way around.

    It seems like a plate is necessary to stabilize the Cloudtec elements. If that were the case, a suggestion would be to sandwich the plate in between the top and bottom elements, akin to the Nike Vaporfly 4%/Nike Zoom Fly 3/Hoka Carbon X.

    Another suggestion could be to add a thin layer of Helion with a softer durometer above the speedboard and have the Cloudtec elements remain as it is. The ride may be greatly improved while maintaining the stability of the elements.

     

     

    That said, the firmness of the shoe may appeal to those looking for a firmer ride. I found the CloudStratus to run quite smoothly at steady paces during easy days where I felt fresh.

    I especially enjoyed them on progression runs, where I increased my pace slightly towards the end of the run. The ride, although firm, is well cushioned and is not in any sense jarring. Vibration dampening is decent, as well.

    Outsole & durability

    Technology

    The outsole uses durable black rubber patches that cover all but the medial part of the shoe. The rubber patches are cut laterally to specifically increase grip when moving forward.

     

    Thoughts

    The outsole has a decent grip. I have not slipped in the shoe even while running after a short thunderstorm.

    I only experienced mild slippage when I picked up the pace on a wet surface. The outsole has great durability and shows little wear after 80km.

     

     

    However, I feel that the traction pattern of the outsole rubber could be improved. Also, using the outsole rubber of a softer durometer could further increase grip while enhancing the ride experience.

     

    Types of workouts

    The On CloudStratus can be used for a variety of paces. It is best used for easy to up-tempo paces (up to half-marathon race pace).

     

    Pros

    • Firm but protective cushioning
    • Smooth transition from heel to toe
    • Most comfortable upper to date from On Running

    Cons

    • Helion is a very firm midsole material
    • The plastic speedboard and the foot is separated merely by an insole, further firming up the ride
    • Leaning towards the heavy side (>300grams)

    Areas of improvement

    • Softer Midsole foam
    • Change of placement of Speedboard
    • Thicker Laces

     

    Comparisons

    On CloudStratus vs. New Balance Fuelcell Propel

    The Fuelcell Propel is lighter and much softer than the firm CloudStratus. The CloudStratus, however, has a superior upper.

    Put the upper of the CloudStratus and the fuelcell midsole of the Propel, and you’ve got yourself a beast of a shoe. The Fuelcell Propel is $110SGD cheaper and has a higher versatility. I’d stick with the Fuelcell Propel.

    On CloudStratus vs. Nike Pegasus Turbo 2

    At 220grams, the Pegasus Turbo 2 is much lighter than the CloudStratus and yet offers cushioning that is both softer and more substantial.

    The upper of the CloudStratus feels plusher and more structured. The Pegasus Turbo 2, on the other hand, has an upper that is more form-fitting and breathable while being thinner. Both shoes are similarly priced.

    With my preference towards a softer ride, I would go for the Pegasus Turbo 2.

    On CloudStratus vs. Asics Kayano 26

    The Asics Kayano line has one of the highest popularity ratings when it comes to daily trainers in the market. With both shoes in the same price range and serving the same purpose, I found it fitting to compare a new market offering with a product that went through 26 versions.

    The CloudStratus is wider and has a noticeably, more comfortable upper. The Asics Kayano is slightly softer but feels clunky in comparison. I’d rather opt for the superior ride and upper construction of the CloudStratus.

    Conclusion

    The On CloudStratus is a firm but protective daily trainer with an excellent upper and an attractive look. Despite being the best On shoe to date, there are necessary improvements that have to be made to keep up in the rapidly growing market of super-foams.

    The On Cloudstratus – Double the layers, double the comfort

    More photos

    The On Cloudstratus, the latest offering from On, is the first shoe that features two layers of Cloudtec pockets on the bottom.

     

     

    The Cloudstratus takes innovation from other On models and molds them into a conglomerate shoe with its twist and design.

    The shoes, like most offerings from On, are built for the road, and it’s here that the Cloudstratus supports the runner the most.

    I own several pairs of On running shoes and have an older model Cloudventure for trail running. I have bought several pairs of On Cloud to run, race, or just wear for when I’m doing chores.

     

     

    I own a pair of the Cloudswift, and I've been wearing the On Cloud Edge (now known as the Cloud Terry) since the shoes first came out. Also, I’m a huge fan of their Cloudflyer and Cloudace shoes.

    The Cloudstratus differentiates itself from other On shoes, predominately because of the double layer of Cloudtec pockets.

    But, On added other features to these shoes that they incorporate from other models as well.

    Design and aesthetics

    The Cloudstratus comes in two color choices for each gender. For men’s shoes, you can go for either Orange and Wash (bright orange and light gray) or Black and Shadow (black and not dark black).

     

     

    For women, the choices are Navy and Wash (dark blue and slightly light blue) or Black and Shadow.

    I do wish that On had more color choices for these shoes because a big, eye-catching feature for the Cloudstratus is the dual-layer Cloudtec pockets.

    This feature is only noticeable from a distance with the Orange and Wash color scheme.

    Personally, I did not get the Orange and Wash colors because I already own a pair of orange running shoes with the On Cloudswift.

    The upper is very breathable. The Cloudstratus has a dual-layer mesh for the toe box upper.

    I feel this shoe was built and designed for summer running, even with the darker color scheme that I chose, because of how breathable and light the upper is.

    The Cloudstratus incorporates the Cloudflyer’s star lacing pattern. It owned this system by using an asymmetric design pattern to help keep the Cloudstratus snugger but without constricting the feet.

     

     

    I love the star lacing system on the Cloudflyer, but On’s engineers took it further with this adjustment on the Cloudstratus.

    The side flaps include two rows of lacing holes. Thus, the wearer has a variety of ways to lace up their shoes.

    While I will leave my laces the way they came on the shoes, I can imagine people going for the wider lacing holes or just creating unique and interesting lacing patterns with the Cloudstratus.

    The Cloudstratus insole features a grip system where your arches are. On talks about proprioception on their blog, which is the body understanding where it is in space.

    I don’t know if the ribbed grooves do help with that, but what I do know is that my heel stays in place with that additional feature, and I attribute it to slightly raised grips.

    As I stated earlier, the Cloudstratus’ sole is comprised of two layers of Cloudtec pockets. The sole also contains On’s own Helion superfoam, which was first seen with the Cloudswift.

    Helion is marketed as lightweight yet durable. I’ve watched and reviewed my footage of the Cloudstratus in action, and the pockets do collapse and bounce right back.

    But after my second run, I did notice some creases forming on the inside edge of the outer Cloudtec pockets on the shoe's bottom.

    These creases do not crack deep, but it is something that I will be observing as I continue to wear them.

    One additional feature to point out is On’s inclusion of their speedboard. The Cloudstratus’s speedboard appears to run from heel to toe, and it is designed to help propel the runner more.

     

     

    From my understanding, On’s speedboard works on the same principle as the springboard in Nike’s Vaporfly 4%, but at a lower price point for the consumer.

    When I did a sprint with the Cloudstratus, I did feel like I was using less energy, and that was a good feeling.

    Overall comfortability

    I wore the Cloudstratus for an entire week, bookending my initial trial period with a run and walking around in them the rest of the time.

    During my initial short run, the back of the shoes felt very comfortable, but I did not notice much for the front. As I wore them more, however, the comfort level increased.

    I don’t know if it’s because I was getting used to the built-in speedboard or On’s fusion of the first four rows of Cloudtec pockets, but I grew more at ease wearing them at work.

    I tend to walk a lot at work. In fact, I think if On made the Cloudstratus without the speedboard, these would be the ideal work shoes for a lot of people who stand or walk during their day. 

    I don’t think I will wear the Cloudstratus without socks, though. I can do that with the On Cloud, the On Cloud Edge (Terry), and even the Cloudswift, but might be one where I keep my socks on.

    This is the heaviest pair of On running shoes that I own. The Helion superfoam may be lightweight, and the upper is very light, but my size US men’s shoes weigh in at 11.7 or 337 grams per shoe.

    Compared to my regular On Cloud sizes that weigh less than 8.5 ounces, it does sound like the Cloudstratus would bog a runner down.

     

     

    I suspect the extra weight comes from the speedboard and the asymmetric hardened back of the shoe.

    Conclusion

    I really like On’s Cloudstratus, but I still have a few reservations before completely recommending these shoes to future users.

    The limited color choices is a more aesthetic issue, but the main concern stems from the On Cloudswift.

    Several people I know who own Cloudswift, even I with my pair of Cloudswift after three months of usage, noticed holes and tears developing on the inside heel area.

    In some cases, these are also found along the top of the back heel of the shoe.

    While my personal Cloudswift shoes’ holes are small, having the fabric break down and tear after only three months is a major issue for a lot of runners, especially when the shoes cost 149.99 USD.

    So, the potential for the 169.99 USD Cloudstratus shoes developing the same holes in the heel area exists. That is why I still recommend trying out the shoes first.

     

     

    On does provide excellent customer service, and they have replaced my friends’ Cloudswift torn shoes.

    And, if these Cloudstratus undergo the same problem, I will most likely use the On customer service to replace the shoes as well.

    If you can get past the possible cosmetic issue, these shoes are great on the feet.

    Pros

    • A lot of cushioning
    • The speedboard helps propel the wearer forward
    • Very breathable upper portion
    • Star lacing pattern helps keep the shoe where it should be
    • Asymmetric front and back help ensure feet are comfortable and functioning
    • Two rows of lacing holes to allow for different lacing patterns and systems
    • Ribbed insole offers more grip for feet and socks

    Cons

    • Heavier than expected
    • Still able to pick up rocks, burrs, and large seeds if you’re not careful
    • The back and sides do not have reflective patches for safer night running
    • Limited color choices

Become an expert

- The Cloudstratus is a product that’s designed for the roads. Unlike other On running shoes, this model has a midsole that is significantly thick. The CloudTec® elements that make up the signature cushioning system now have two layers and they run from the midfoot to the heel. A Speedboard™ layer bolsters the push-off ability of the midsole, further energizing each step.

- Providing a secure yet accommodating wrap is an asymmetrical mesh. This curved and stretchy material mimics the natural motion of the foot. It is even accompanied by a set of laces that snake through discreet and well-spaced eyelets, Such a design prevents hot spots and permits the normal swelling of the foot as it accesses the gait cycle.

The On Cloudstratus was created using the standard sizing scheme. Runners are welcome to get a pair using their usual sizing expectations. However, it is worth noting that testing the shoe from brick and mortar stores and getting ahold of user reviews from online sites can help with the attainment of a comfortable in-shoe experience.

When it comes to width, the available options are D - Medium and B - Medium for men and women, respectively. Those with low or medium foot dimensions are the ones who are going to acclimate well inside the compartment of this product.

The outsole unit of the On Cloudstratus is made of CloudTec® rubber. This external layer encompasses the contact points of the forefoot, lateral midfoot and heel, ensuring protection from abrasion as the foot transitions through the gait cycle. The naturally grippy nature of rubber accommodates precise movements, particularly when braking, strafing or swerving.

The unique pod-like structure of this product’s cushioning system gives rise to the presence of flex grooves. These deep trenches make the platform as flexible as possible, thereby allowing the natural flexibility of the foot to take its course through the movement cycle. The toe-off phase is the part of the step that benefits the most from such a feature because it involves the bending of the toe joints and tendons.

Underfoot cushioning is the responsibility of the CloudTec® platform. This technology runs the entire length of the On Cloudstratus, supporting the whole of the foot and keeping it from impact shock. While there is a topsole that welcomes the outline of the foot, the highlight of the CloudTec® are the pod-like ‘elements’ which grace the very bottom of it. These nodes are meant to provide targeted protection from impact and promote energized takeoffs. It now has a dual-layer design (from the midfoot to the heel) to put some emphasis on a strong and unrelenting cushioning capacity.

The entire midsole is made of Helion™, a Swiss-engineered foam that is meant to enhance the performance of the wearer without sacrificing flexibility or the weight of the shoe. It aims to attenuate impact shock during the striking phase, return energy to the foot during the toe-off, and retain its structure, even when exposed to the changing temperatures of the outdoors.

An arch-ribbed sockliner is placed right on top of the primary cushioning system. This add-on offers a bit of extra oomph to the underfoot experience. It has a raised medial midfoot portion to buttress the arch, thus keeping it from buckling at any point during the run.

The upper unit of the On Cloudstratus is made of mesh that has been engineered to follow the anatomical shape and movement capacity of the human foot. It has a slightly convex ceiling to reduce pressure on the bridge of the foot. It also has a rounded forefoot section to encourage the natural splaying of the toes. Minute breathing holes let environmental air inside the foot-chamber, thus maintaining a cool and dry wrap.

The overlay system is made of an amalgamation of fused synthetic sheets, a wraparound midfoot panel that covers both the lateral and medial sides, and stitch-reinforcements. All these kinds of overlays have the job of preventing in-compartment wobbling and accidental shoe removals.

The lacing system is the traditional loop-and-tie configuration, but the eyelet placement is made up of the star configuration, which means that there are plenty of asymmetrical, discreet eyelets on the instep (to allow for custom spacing of the zigzag shoelaces), and a couple of stretchy cords on the vamp (for toe joint flexibility and fit adjustment on the front of the upper unit).

The lightly padded collar and tongue are tasked with cushioning the Achilles tendon, the ankles, and the bridge of the foot.

The ‘ON’ logos that adorn the silhouette provide brand recognition. Each of these symbols has a reflective coat that makes the shoe more visible in low-light. All of On’s running shoes have this feature, including the original model, the venerable On Cloud.
