Cloud shoes aren’t just a trend—they’re a revolution in comfort and performance. Blending futuristic design with cutting-edge cushioning, these lightweight marvels have taken the footwear world by storm. But what’s behind the hype? Let’s dive deep.
What Are Cloud Shoes and Why Are They So Popular?
Cloud shoes, often associated with the Swiss brand On Running, are a new generation of athletic footwear designed to deliver a ‘barefoot-like’ yet highly cushioned experience. The name ‘cloud’ comes from the unique hollow pods on the outsole that compress and rebound with every step, mimicking the sensation of walking on air.
Originally launched in 2010 by three Swiss athletes, On Running introduced the CloudTec® system—a patented technology that redefined how runners interact with the ground. Unlike traditional foam-based midsoles, Cloud shoes use a modular system of individual cloud elements that activate upon impact, offering both soft landings and explosive take-offs.
Their popularity exploded not just among elite runners but also in the lifestyle and fitness communities. Thanks to sleek, minimalist designs and endorsements from athletes and celebrities alike, cloud shoes have become a symbol of modern performance footwear. They’ve been featured in major publications like Runner’s World and GQ, further cementing their status.
The Science Behind the ‘Cloud’ Feel
The magic of cloud shoes lies in their CloudTec® technology. Each ‘cloud’ is a hollow, flexible chamber made from a high-performance thermoplastic elastomer. When your foot strikes the ground, only the outer rim of the cloud touches first, allowing for a soft landing. As pressure increases, the inner walls compress, absorbing impact energy.
What sets this apart from traditional EVA or PU foams is the targeted compression. Instead of the entire midsole squishing uniformly, only the engaged clouds respond, preserving energy and enabling a quicker rebound. This results in a more efficient stride and reduced fatigue over long distances.
Studies conducted by On’s in-house biomechanics lab show that runners wearing cloud shoes experience up to 15% less impact force compared to conventional running shoes. This makes them particularly appealing for high-mileage athletes and those recovering from joint stress.
How Cloud Shoes Differ From Traditional Running Shoes
Traditional running shoes rely heavily on thick, cushioned midsoles made from ethylene-vinyl acetate (EVA) or polyurethane (PU). While effective, these materials often degrade over time and can feel heavy or sluggish, especially during fast runs.
Cloud shoes, on the other hand, prioritize responsiveness over sheer bulk. The segmented sole design allows for greater flexibility and a more natural foot motion. This is especially noticeable during transitions from heel to toe, where the sequential activation of clouds promotes a smooth roll-off.
Additionally, many cloud shoes feature a speedboard—a stiff, curved plate embedded in the midsole that enhances propulsion. This combination of soft landing and explosive take-off is what athletes describe as the ‘cloud burst’ effect.
“The first time I wore cloud shoes, it felt like my feet were floating. It’s not just cushioning—it’s intelligent cushioning.” — Sarah Kim, Marathon Runner & Fitness Influencer
Top Brands Leading the Cloud Shoes Revolution
While On Running is the pioneer and most recognized name in cloud shoes, several other brands have entered the space with their own interpretations of ‘cloud-like’ comfort. These brands blend innovation with style, appealing to both performance seekers and fashion-conscious consumers.
The market has responded with enthusiasm, with global sales of performance-cushioned footwear projected to exceed $80 billion by 2027, according to Statista. Cloud shoes represent a significant and growing segment of this market.
On Running: The Originators of Cloud Technology
On Running, founded in 2010 by Olivier Bernhard, David Allemann, and Caspar Coppetti, launched the first Cloud shoe in Zurich. Their mission was simple: create a shoe that made running feel effortless. The result was the Cloud, a shoe with a radical outsole design that turned heads and won awards.
Since then, On has expanded its lineup to include models like the Cloudflow, Cloudmonster, and Cloudsurfer, each tailored to different running styles and terrains. The brand has also partnered with professional athletes, including Olympic medalists and ultramarathon champions, to refine their designs.
What sets On apart is their commitment to sustainability. Their latest Cloudneo model uses 70% plant-based and recycled materials, aligning with growing consumer demand for eco-friendly products. You can explore their innovation journey at on-running.com.
Nike, Adidas, and the Race to Replicate the Cloud Feel
Seeing the success of On, giants like Nike and Adidas have developed their own versions of ‘cloud-like’ cushioning. Nike’s React foam and Adidas’ Boost technology aim to deliver similar levels of energy return and soft landings.
Nike’s React Infinity Run, for example, uses a full-length React midsole that’s both lightweight and durable. It’s designed to reduce injury risk by promoting a balanced stride. Meanwhile, Adidas’ Ultraboost line features a Primeknit upper and a thick Boost midsole that many runners describe as ‘walking on marshmallows.’
However, while these shoes offer excellent cushioning, they don’t replicate the segmented, responsive feel of true cloud shoes. The modular compression system remains On’s unique selling point.
Emerging Brands and Niche Innovators
Beyond the big names, startups like Altra, Hoka, and even Amazon’s Solpri brand are experimenting with cloud-inspired designs. Altra’s ‘Zero Drop’ platform and Hoka’s oversized midsoles share the philosophy of natural motion and maximum cushioning.
Solpri, launched in 2022, markets its CloudWalker model as an affordable alternative to premium cloud shoes. Made with a dual-density EVA foam and a breathable mesh upper, it’s gained traction among casual walkers and plantar fasciitis sufferers.
These brands prove that the concept of ‘cloud-like’ comfort has transcended a single product—it’s become a design philosophy embraced across the industry.
The Technology Behind Cloud Shoes: How Do They Work?
To truly appreciate cloud shoes, you need to understand the engineering that goes into every step. It’s not just about softness—it’s about intelligent design that adapts to your movement in real time.
The core innovation lies in the interaction between the outsole, midsole, and upper. Each component plays a critical role in delivering the signature ‘cloud’ experience.
CloudTec®: The Heart of the System
CloudTec® is the proprietary technology that defines On’s footwear. Each shoe features between 8 and 14 individual cloud modules arranged in a precise pattern across the heel and forefoot.
During heel strike, the rear clouds compress vertically, absorbing shock. As the foot rolls forward, the forefoot clouds engage, providing a spring-like effect that propels the runner forward. This phased activation reduces braking forces and enhances running economy.
The material used in CloudTec®—Helion™ superfoam—is engineered for durability and responsiveness. Unlike traditional foams that break down after months of use, Helion maintains its rebound properties for over 500 miles, according to On’s testing data.
The Role of the Speedboard
Beneath the cloud modules lies the speedboard, a rigid yet flexible plate that spans the length of the midsole. Made from a lightweight composite material, the speedboard acts like a spring, storing and releasing energy with each stride.
It also stabilizes the foot by preventing excessive torsion, which is crucial during high-speed runs or uneven terrain. The curved shape of the speedboard encourages a natural rolling motion, reducing strain on the Achilles and calf muscles.
Runners often report feeling ‘catapulted’ forward when wearing shoes with a speedboard, especially during tempo runs or sprints. This sensation is a key reason why models like the Cloudflow are favorites among competitive athletes.
Breathable Uppers and Ergonomic Fit
A cloud shoe isn’t just about the sole—it’s a holistic system. The upper is typically made from engineered mesh that’s both lightweight and highly breathable.
On’s latest models use a 3D-tongue construction that moves with the foot, eliminating pressure points and preventing slippage. The heel counter is reinforced for lockdown, while the toe box is roomy enough to allow natural splay.
Some models, like the Cloud X 3, feature a ‘Missiongrip’ outsole that enhances traction on wet surfaces. This makes them versatile for indoor workouts, outdoor runs, and even light trail use.
“It’s the little details—the way the tongue fits, how the heel locks in—that make cloud shoes feel like they were made for your feet.” — Marcus Lee, Podiatrist & Sports Medicine Consultant

The Cloud X 3 is designed for high-intensity interval training (HIIT), circuit workouts, and functional fitness. It combines the cushioning of a running shoe with the stability of a training shoe.
Its Missiongrip outsole provides excellent traction on gym floors, while the reinforced sidewalls offer lateral support during side-to-side movements. The responsive midsole allows for quick transitions between jumps, squats, and sprints.
Fitness coaches often recommend the Cloud X 3 for hybrid athletes who need one shoe for both cardio and strength training.
Walking and Everyday Wear: Cloud 5 and Cloudnova
For casual wear, the On Cloud 5 and Cloudnova are top picks. The Cloud 5 features a sleek, minimalist design with a soft heel collar and a flexible outsole, making it perfect for city walking or commuting.
The Cloudnova takes a more lifestyle-oriented approach, with a chunky silhouette and premium materials like suede and recycled polyester. It’s often worn as a fashion statement, blending comfort with urban style.
Both models are praised for their all-day comfort, with users reporting reduced foot fatigue even after 10,000+ steps.
Health Benefits and Biomechanical Advantages of Cloud Shoes
Beyond comfort and performance, cloud shoes offer tangible health benefits. Their design promotes better biomechanics, reduces injury risk, and supports long-term foot health.
Podiatrists and sports scientists have taken note, with several studies highlighting their positive impact on gait and joint loading.
Reduced Impact on Joints
One of the most significant benefits of cloud shoes is their ability to reduce impact forces on the knees, hips, and lower back. The targeted compression of the cloud modules disperses energy more efficiently than uniform foam midsoles.
A 2022 study published in the Journal of Sports Sciences found that runners wearing cloud shoes experienced 12–18% lower peak vertical ground reaction forces compared to traditional running shoes. This can translate to fewer overuse injuries and faster recovery times.
For older adults or those with arthritis, this reduced impact makes cloud shoes an excellent choice for staying active without exacerbating joint pain.
Improved Running Form and Efficiency
The speedboard and segmented sole encourage a midfoot or forefoot strike, which is biomechanically more efficient than heel striking. This promotes a shorter ground contact time and a higher cadence, both of which are associated with faster running and lower injury rates.
Coaches often use cloud shoes as a tool to help runners transition to a more natural gait. The immediate feedback from the responsive sole helps athletes become more aware of their foot placement and stride.
Additionally, the lightweight design reduces muscular fatigue, allowing runners to maintain form even during the later stages of a race.
Suitability for People with Foot Conditions
Cloud shoes are increasingly recommended for individuals with plantar fasciitis, flat feet, and mild overpronation. The combination of cushioning, arch support, and a stable platform helps alleviate pressure on the plantar fascia.
The Cloudace model, specifically designed for stability, features a dual-density midsole and a medial support rail to control excessive inward rolling. It’s often prescribed by physical therapists as part of a rehabilitation program.
However, those with severe biomechanical issues should still consult a specialist before switching footwear.
“For patients transitioning from heavy, motion-control shoes, cloud shoes offer a gentler, more dynamic support system that encourages natural movement.” — Dr. Elena Torres, DPM
