ON Cloudboom Strike Review: Precision Racing Redefined

Prateek Mishra / Leave a Comment / On, Running Shoes / March 24, 2025

The marathon shoe arena is crowded with bouncy super foams and aggressive carbon plates, but ON’s Cloudboom Strike takes a different approach. Instead of chasing max energy return, it blends Swiss-engineered precision with a balanced ride that feels both propulsive and controlled. Designed for race day but tempting enough for speed sessions, this shoe targets runners who crave a mix of cushioning and responsiveness without the “trampoline effect.” In this ON Cloudboom Strike review, we dissect a marathon shoe designed for runners who value precision over hype. Does its blend of Swiss-engineered stability and carbon propulsion justify the $280 price tag? Let’s dig in.

Key specifications:

Brand: On
Model: Cloudboom Strike
Weight: 8.5 oz (241g) for US 9 model
Heel: 39.5 mm
Toe: 35.5 mm
Heel drop: 4 mm
Carbon plate: Yes

Price of ON Cloudboom Strike

Price: $280 USD
Release date: September 1, 2024

Upper Review: Snug, Secure, and Breathable

The Cloudboom Strike’s upper is all business. A single-layer engineered mesh wraps the foot like a second skin—thin, almost translucent, and dotted with laser-cut perforations for airflow. It’s surprisingly durable, avoiding the fragile feel of some race-day uppers. The gusseted tongue stays put without bulk, and ON’s signature “wing” eyelets create a lockdown that hugs the midfoot.

Around the heel, a rigid external counter and plush internal padding strike a rare balance: secure enough to prevent slippage during sharp turns, yet soft enough to avoid blistering. Runners with wider feet might find the toe box snug, but the mesh stretches subtly over time. One gripe? The laces are slick and prone to loosening—swap them for elastic Lock Laces if you’re picky.

Midsole Review: Where CloudTec Meets Carbon

ON’s Helion Hyper foam takes center stage here. Unlike the marshmallow-soft midsoles dominating the market, this one feels firmer at first touch but softens intelligently under load. The redesigned CloudTec Phase pods compress vertically to cushion impact, then snap back to propel you forward. Paired with a full-length carbon Speedboard, the result is a ride that’s more “controlled pop” than “wild rebound.”

The rocker geometry is subtle but effective. During testing, marathoners praised how the shoe transitions smoothly from heel to toe, reducing calf strain over long miles. The removable insole adds a touch of customization, though most testers kept it in for a plush underfoot feel. Warning: The high stack demands some ankle stability. New runners or heel strikers might need a break-in period to adapt.

Outsole Review: Grip That Sticks (Mostly)

ON ditched the traditional rubber slab for a strategic approach. Exposed Helion Hyper foam forms the bulk of the outsole, with carbon rubber pads glued to high-wear zones. The result? A grippy, flexible tread that claws into pavement, even on damp roads. While not as rugged as a daily trainer’s outsole, it held up through 100+ miles in testing with minimal wear. The CloudTec pods double as traction points, flexing naturally with your stride. However, gravel or muddy paths are a no-go—this is a road warrior through and through.

Who Should Buy This Shoe?

Marathoners and Half-Marathoners: The cushioning lasts for 26.2 miles without fading.
Neutral Runners Seeking Precision: If you dislike overly bouncy shoes, this offers a stable, connected ride.
Speedwork Enthusiasts: Perfect for tempo runs or intervals when you want to practice race-day feel.

Who Should Skip It?

Overpronators: Zero stability features here.
Daily Trainers: The price and specialized design scream “special occasions only.

Verdict

The ON Cloudboom Strike isn’t here to revolutionize racing shoes—it’s here to refine them. It trades gimmicks for a polished, reliable ride that shines over long distances. While the firm-ish midsole won’t please everyone, it’s a stealthy pick for runners who value control as much as speed. Add the breathable upper and durable outsole, and you’ve got a shoe that’s ready to tackle PRs without coddling your feet.

Just don’t expect it to double as a daily trainer. This is a specialist, and it’s priced like one (though if you’re curious about a softer, more versatile ON option, check out my Cloudsurfer 2 review for a shoe that’s built for everyday miles). If you’re hunting for a marathon shoe that feels like an extension of your stride rather than a rocket strapped to your feet, the Cloudboom Strike deserves a spot on your shortlist.

On Cloudsurfer 2 Review: The Smoothest Ride or Just Hype?

Prateek Mishra / 1 Comment / On, Running Shoes / February 15, 2025

The On Cloudsurfer series has carved a niche in the running world with its signature blend of Swiss precision, lightweight design, and adaptive cushioning. With the Cloudsurfer 2, On Running takes a bold leap forward, reimagining the shoe from the ground up. This latest iteration ditches the divisive Speedboard of its predecessor and introduces a fresh midsole philosophy, all while doubling down on sustainability. Designed for runners who crave a plush yet versatile daily trainer, the Cloudsurfer 2 aims to balance innovation with eco-consciousness. Let’s unpack its upgrades, performance, and whether it lives up to the hype.

What’s New in the On Cloudsurfer 2?

The Cloudsurfer 2 represents a radical redesign rather than a minor refresh. The most notable change is the elimination of the Speedboard, a rigid plate that polarized runners in the original model. In its place, On introduces CloudTec Phase, a midsole technology featuring wave-like pod geometry that promotes smoother transitions and natural flexibility. Sustainability also takes center stage, with 20% of the upper now crafted from recycled materials. The fit has been refined with a gusseted tongue and simplified lacing system to address heel slippage complaints, while the softer Helion supercritical foam midsole delivers a more forgiving ride. Combined, these updates position the Cloudsurfer 2 as a gentler, more eco-friendly companion for daily miles.

Key specifications:

Brand: On
Model: Cloudsurfer 2
Weight: 9 oz. (257 g) for US 9 model
Heel: 32 mm
Toe: 23 mm
Heel drop: 9 mm
Carbon plate: No plate

Cushioning & Ride

Amount of cushioning: Highly cushioned
Purpose: Daily Trainer

Price of On Cloudsurfer 2

Price: $160 USD

Upper

The Cloudsurfer 2’s upper showcases On’s commitment to sustainability without compromising performance. Constructed from a dual-layer engineered mesh comprising 20% recycled polyester, it strikes a balance between breathability and structure. The redesigned gusseted tongue is a standout upgrade, locking the foot in place and minimizing debris ingress during off-road excursions. Strategic padding around the heel collar and achilles tendon adds comfort, while the slightly roomier toe box accommodates natural foot splay without feeling sloppy. Though the midfoot remains snug—a hallmark of On’s fit—the overall design feels more forgiving than previous models, wrapping the foot in a secure, sock-like embrace.

Midsole

The removal of the Speedboard allows the new CloudTec Phase midsole to shine. Built with Helion supercritical foam—a nitrogen-infused compound—the midsole features a series of wave-shaped pods that compress progressively underfoot. This design eliminates the abrupt “crash” feel of the original Cloudsurfer, replacing it with a smoother, more organic transition from heel to toe. The foam itself strikes a delicate balance: soft enough to absorb road shock during recovery runs, yet sufficiently resilient to handle uptempo efforts. Runners will appreciate the enhanced flexibility, which reduces leg fatigue over long distances. While it lacks the explosive energy return of plated racers, the Cloudsurfer 2’s midsole excels as a jack-of-all-trades workhorse.

Outsole

On has taken a targeted approach to the Cloudsurfer 2’s outsole, applying durable rubber only to high-wear zones like the heel and forefoot. The geometric tread pattern improves grip on wet pavement and loose gravel, a subtle upgrade from the v1’s simpler layout. However, exposed foam in the midfoot area remains a durability concern, particularly for heel strikers or heavier runners. While testers noted improved longevity compared to the original, the outsole still shows visible wear after 250–300 miles. That said, the minimalist design keeps weight in check, aligning with the shoe’s ethos as a lightweight cruiser.

Who Is This Shoe For?

The Cloudsurfer 2 is tailored for neutral runners seeking a do-it-all daily trainer that excels on roads, bike paths, and light trails. Its 8mm drop and rockered geometry cater to midfoot strikers, though heel strikers will still find the cushioning forgiving enough for long runs. Eco-conscious athletes will appreciate its recycled materials, while fans of On’s signature style will love its sleek, modern aesthetic. However, it’s not ideal for speed-focused workouts (opt for the Cloudboom Echo) or runners requiring stability features.

Pros

✅ Plush, adaptable ride return
✅ Lightweight for a max-cushion shoe
✅ Eco-friendly materials (20% recycled)

Cons

❌ Outsole durability still questionable
❌ Less responsive for speedwork
❌ Slightly narrow midfoot for wide feet

Verdict

The On Cloudsurfer 2 is a revelation—a shoe that learns from its predecessor’s flaws while pushing the brand’s design ethos forward. By shedding the Speedboard and embracing CloudTec Phase, On has crafted a daily trainer that feels softer, smoother, and more intuitive than ever. While the outsole’s durability may give pause to some, the Cloudsurfer 2’s blend of cushioning, weight, and sustainability makes it a standout choice for runners seeking versatility and comfort. For those craving a plated counterpart for race-day speed, consider pairing these with On’s Cloudmonster Hyper, a shoe engineered for explosive energy return and podium-chasing paces. Together, they form a dynamic duo for runners who value both daily comfort and competitive edge. At $150, the Cloudsurfer 2 is a compelling option for eco-minded athletes and On loyalists alike.

On’s Cloudboom Strike LS Spray-On Shoe is Here

Prateek Mishra / Leave a Comment / News, On / July 16, 2024

In a groundbreaking move that promises to redefine the future of running footwear, Swiss sportswear brand On has introduced its latest innovation: the Cloudboom Strike LS. Known for their revolutionary CloudTec sole, On is once again set to disrupt the market with this state-of-the-art spray-on running shoe. In a captivating video, the entire process of creating the Cloudboom Strike LS unfolds in just three minutes. From a single 1.5 km thread, a robot weaves the upper and seamlessly attaches it to the midsole—no glues, no seams.

The Birth of a Revolution

The Cloudboom Strike LS, where LS stands for LightSpray, showcases cutting-edge technology and meticulous design. Crafted from a single semi-translucent synthetic monofilament nearly a mile long, the shoe is extruded by a robot arm and engineered to perfectly fit the feet of elite runner Hellen Obiri. This unique process ensures optimal running efficiency, with the upper heat-fused to a foam rubber and carbon-fiber sole, resulting in an ultra-lightweight shoe weighing just 170 grams (about six ounces).

Eco-Friendly Engineering

Beyond its innovative design, the Cloudboom Strike LS represents a significant step forward in sustainable footwear. On reports that the shoe has 75 percent less environmental impact than traditional sneakers. With only seven components compared to the usual 150 to 200, the shoe is manufactured with precision and minimal human intervention. Parametric design principles and computational engineering replace traditional pattern-making, reducing the need for manual labor and factory assembly lines.

A Leap in Manufacturing

The production of the Cloudboom Strike LS takes place in new “production cells” located in Zurich and other key markets, rather than outsourced factories in Asia. This localized manufacturing approach drastically shortens the time between production and delivery. Remarkably, the Cloudboom Strike LS can transition from midsole to finished product in just three minutes. This efficiency eliminates waste and reduces carbon emissions by avoiding unnecessary transportation and leftover materials.

Sustainable to the Core

In a bid to further enhance sustainability, the Cloudboom Strike LS features color added via inkjet rather than traditional fabric dyeing methods. The thermoplastic filament used for the upper can be melted down and reused at the end of the shoe’s life cycle, ensuring a cradle-to-cradle design. This forward-thinking approach minimizes environmental impact and reduces stock left at the end of each season, as production can be closely matched to demand.

The Future of Footwear

On’s creation of the Cloudboom Strike LS involved building custom machines to weave the filament according to the biomechanics of the foot. This high-stakes investment in both technology and philosophy underscores On’s commitment to pushing the boundaries of what’s possible in running footwear. The result is a shoe that offers unparalleled support, breathability, and performance, all while prioritizing environmental sustainability.

The unveiling of the Cloudboom Strike LS marks a significant milestone in the evolution of running shoes. With its revolutionary design, eco-friendly production, and advanced engineering, On has set a new standard for performance and sustainability in sportswear. The Cloudboom Strike LS is not just a shoe; it’s a glimpse into the future of footwear. Prepare to be amazed and inspired as you lace up the Cloudboom Strike LS and experience the next generation of running technology.

On Cloudmonster Hyper Review

Prateek Mishra / 1 Comment / On, Running Shoes / April 5, 2024

Guess what? On just added another masterpiece in the Cloudmonster family, and it’s barely been two months since the Cloudmonster 2 hit the shelves. On’s on fire with their latest addition, delivering a sleek and top-notch product that screams efficiency and premium quality in both looks and performance. Say hello to the On Cloudmonster Hyper – these are not just your average running shoes. They’re high-performance running shoes, ticking all the boxes for versatility and comfort. With enhanced durable cushioning and a comfort level that’s off the charts, these shoes promise to elevate every single one of your runs. So, buckle up as I dive into my take on this ultimate super trainer, while also breaking down the differences between the Cloudmonster Hyper and its predecessor, the Cloudmonster 2.

Key Specifications of Cloudmonster Hyper:

Brand: On
Model: Cloudmonster Hyper
Weight: 9.3 oz (265 grams)
Heel: 37.5mm
Toe: 31.5 mm
Heel drop: 6 mm

Cushioning & Ride

Amount of cushioning: Highly cushioned
Stability: Neutral
Usage: Long & Daily training

Release Date & Price of Cloudmonster Hyper:

Release Date: 4th April 2024
Price: $220

Upper

The upper of the On Cloudmonster Hyper blends the finest features from On’s shoe collection seamlessly. It’s thinner than its namesake, ensuring breathability without compromise. With ample padding, comfort is a given. The ankle cut is now more traditional, rounded, and softer, departing from the square cut of the Cloudmonster. The tongue is thin yet well-padded in key areas, enhancing midfoot lockdown and ensuring a cozy fit. And let’s talk laces—they’re decent and slightly rubberized, offering a secure tie-up that keeps your foot firmly in place.

Midsole

The midsole of the On Cloudmonster Hyper running shoe sees a noticeable shift in design. On CloudTec technology remains a key feature, with its distinct CloudTec pods adorning the midsole. However, there’s a significant alteration in materials: Helion foam extends from the heel to the forefoot, while PEBA foam is injected into the front half of the shoe. This difference is clearly visible through the contrasting colors—white for PEBA foam in the front and green/orange highlighting the Helion foam in the back, comprising the majority of the midsole. Helion, known for its resilience and effectiveness, has been a staple in On shoe midsoles for several years. What sets this running shoe apart is the introduction of PEBA foam in the forefoot, promising an exciting change in performance.

Outsole

The outsole of the On Cloudmonster Hyper shares a lot in common with its predecessor, the Cloudmonster. However, you’ll notice a bit more rubber on the Hyper version. Here’s the cool part: every cloud is connected by a strip, giving you extra coverage and shielding the midsole foam from the rough roads. They’ve strategically placed the rubber where it matters most, especially at the back of the heel for those who tend to strike there. So, whether you’re pounding the pavement or hitting the trails, the Hyper’s got your back – or rather, your feet!

On Cloudmonster Hyper VS Cloudmonster 2

Alright, let’s break down the differences between On Cloudmonster Hyper and Cloudmonster 2. So, picture this: with the Hyper, you’ve got this bouncy PEBAX foam on top and Helion foam at the bottom, giving you some serious bounce. But here’s the twist – no plastic speed board in the middle. Now, switch gears to the Cloudmonster 2. It’s got that plastic speed board, with a softer Helion foam on top and a firmer version below. Oh, and here’s a fun fact: the Hyper is lighter by almost a full ounce and has a slightly taller stack height by about 3 millimeters, all with the same drop.

Our Verdict

Overall, the Cloudmonster Hyper stands out as a top-notch running shoe, surpassing its predecessors with its impressive performance. Whether you’re tackling tough endurance runs or just going for a casual jog, this shoe delivers. It’s clear that I’ll be logging many miles in it in the months ahead.

Heel: 35 mm
Toe: 29 mm
Heel drop: 6mm
Sizing: True to size

Cushioning & Ride

Amount of cushioning: Medium cushioning
Stability: Very much stable, much more so than the original Cloudmonster
Usage: Everyday training and tempo runs

Price & Availability

Price: $179
Release date: February 22, 2024

Upper

The Upper of the newly launched ON Cloudmonster 2 running shoes introduces exciting upgrades, focusing on enhanced comfort and functionality. The standout features include a redesigned heel collar and an improved lacing system. The new heel collar boasts increased padding, providing a plush feel that surpasses its predecessor. Not only does it deliver superior comfort, but it also ensures a more secure heel lockdown. Moving on to the lacing system, it may not be flashy, but it gets the job done seamlessly. In contrast to the original Cloudmonster’s short and angled lacing pattern, the Cloudmonster 2 adopts a longer, straight design with additional eyelets, positioned at the center of the upper. Functionally, it performs admirably, delivering a delightful lacing experience.

The On Cloudmonster 2 embodies the essence of subtle yet effective updates, allowing users to seamlessly transition from the original model while enjoying improved features that don’t overpower the familiar charm of the original.

Midsole

In the world of running shoes, the ON Cloudmonster 2 brings a refreshing upgrade to the midsole, promising an enhanced cushioning experience through its innovative dual-density foam construction. Wearing the new Cloudmonster 2, it’s easy to mistake it for its predecessor – that is until you start running. The changes are subtle, tailored to satisfy the most dedicated Cloudmonster enthusiasts. While the midsole maintains a familiar firmness level akin to the original, the forefoot surprises with reduced ground feel and a more substantial cushioning sensation. The denser and compact slab of foam beneath the metatarsals significantly improves forefoot shock absorption. The heel, reminiscent of the original, ensures a consistent feel.

Despite not returning much energy, the midsole’s superb impact absorption at various paces stands out, thanks to the Nylon blend Speedboard and its redesigned shape. Similar to the Cloudflow, the new Speedboard maximizes the forward motion between the midfoot and forefoot, making the ON Cloudmonster 2 excel in diverse running scenarios. It may not be immediately apparent, but this design choice explains why the shoe effortlessly performs across the board.

Outsole

Now, let’s talk about the bottom of the ON Cloudmonster 2 running shoes – the outsole. The outsole boasts a new design with a shallower central groove pattern, ensuring that pesky gravel and tiny debris don’t play hide-and-seek in your shoes. Unlike its predecessor, the Cloudmonster 2 won’t be collecting rocks along the way. This tweak makes a world of difference, making your running experience smoother and hassle-free. It’s a noteworthy upgrade that addresses a real-world issue.

Pros & Cons

Pros:
High quality On craftsmanship
Breathable upper
No slippage in wet condition
Stable and supportive

Cons:
Heavier than original Cloudmonster
$180 seems expensive for this shoe

Our Verdict

In conclusion, the On Cloudmonster 2, though delivering a firmer ride catering to those averse to overly squishy running shoes, falls short of surpassing its predecessor’s versatility and agility. While it may not be my top choice, there are other highly-cushioned alternatives in the market that excel in both comfort and adaptability, such as the Puma Magnify Nitro 2, HOKA Mach 5, Brooks Ghost Max, and Saucony Triumph 21. The Cloudmonster 2, with its distinctive features, targets a specific preference in footwear, but the diverse landscape of cushioned shoes offers compelling options that suit a variety of needs and preferences.
