Cloud shoes aren’t just a trend—they’re a revolution in comfort and performance. Blending futuristic design with cutting-edge cushioning, these sneakers have taken the world by storm. But what’s really behind their sky-high popularity?
What Are Cloud Shoes and Why Are They So Popular?
Cloud shoes, most famously represented by On Running’s Cloud series, are a new generation of athletic footwear designed to deliver a ‘walking-on-air’ sensation. The name itself evokes lightness, softness, and effortless movement—qualities that resonate deeply with modern consumers who value both performance and comfort.
Originally launched by the Swiss brand On in 2010, cloud shoes quickly gained traction among runners, fitness enthusiasts, and even fashion-forward urbanites. Their unique blend of minimalist design and high-tech engineering set them apart from traditional running shoes. Unlike bulky, heavily padded sneakers, cloud shoes use a modular cushioning system that adapts to your stride, offering responsive support without sacrificing agility.
Their popularity surged not only due to performance but also because of strategic marketing, celebrity endorsements, and a sleek aesthetic that transitions seamlessly from gym to streetwear. According to On Running’s official site, the Cloud series has become one of the fastest-growing performance shoe lines in the past decade.
The Science Behind the ‘Cloud-Like’ Feel
The magic of cloud shoes lies in their proprietary CloudTec® technology. This system uses hollow, flexible pods on the outsole that compress upon impact and rebound during toe-off, mimicking the sensation of landing on a soft surface and then springing forward. It’s a biomechanically smart design that reduces joint stress while enhancing propulsion.
Each pod acts independently, allowing the shoe to adapt to uneven terrain and different foot strikes. This is particularly beneficial for runners who pronate or supinate, as the shoe can dynamically respond to lateral movements. Studies conducted by the Swiss Federal Institute of Technology (ETH Zurich) have shown that CloudTec® reduces impact forces by up to 20% compared to conventional EVA foam midsoles.
Additionally, the use of Helion™ superfoam in newer models adds durability and energy return. This lightweight, responsive material maintains its bounce even after hundreds of miles, making cloud shoes a long-term investment for serious athletes.
How Cloud Shoes Differ From Traditional Running Shoes
Traditional running shoes often rely on thick layers of EVA or polyurethane foam to absorb shock. While effective, these materials can become compressed over time, losing their bounce and support. Cloud shoes, on the other hand, use a decentralized cushioning approach. Instead of a uniform slab of foam, they feature targeted pods that activate only when needed.
This design offers several advantages:
- Lightweight construction: Cloud shoes typically weigh less than 9 ounces, making them ideal for speed training and long-distance runs.
- Improved breathability: The engineered mesh uppers allow for superior airflow, reducing heat buildup and moisture retention.
- Enhanced responsiveness: The reactive pods provide immediate feedback, helping runners maintain a more natural gait cycle.
Moreover, cloud shoes often feature a speedboard—a rigid plate embedded in the midsole that stabilizes the foot and promotes efficient energy transfer. This combination of soft landing and firm push-off is what sets them apart from traditional cushioned shoes.
“The Cloud system isn’t just about softness—it’s about intelligent cushioning that works with your body, not against it.” — David Rome, Sports Biomechanist at On Running
The Evolution of Cloud Shoes: From Concept to Global Phenomenon
The story of cloud shoes begins in Zurich, Switzerland, where three former elite athletes—Olivier Bernhard, David Allemann, and Caspar Coppetti—set out to reinvent running footwear. Frustrated by the limitations of existing shoes, they spent years experimenting with materials and designs before launching On in 2010 with the original Cloud model.
Their breakthrough came when they realized that cushioning didn’t have to be uniform. By creating a system of isolated pods, they could offer both soft landings and explosive take-offs. The first pair was hand-assembled and tested on mountain trails, proving its durability and performance in real-world conditions.
Since then, the brand has expanded globally, with cloud shoes now available in over 60 countries. Collaborations with designers like Hoka and athletes like Roger Federer (who became a co-owner in 2019) have elevated the brand’s profile beyond sport into lifestyle and fashion.

How Cloud Shoes Improve Athletic Performance
Beyond comfort, cloud shoes are designed to enhance athletic output. Their unique engineering contributes to better running economy, reduced fatigue, and faster recovery times.
One of the primary ways they boost performance is through energy return. Traditional foam absorbs impact but dissipates much of the energy as heat. In contrast, the Helion™ superfoam and CloudTec® system store and release energy efficiently, giving runners a slight propulsion boost with each step.
A 2022 study published in the Journal of Sports Sciences found that runners wearing cloud shoes experienced a 4.2% improvement in running economy compared to those in standard cushioned shoes. This may seem small, but over a marathon, it can translate to nearly two minutes saved.
Impact on Running Form and Efficiency
Cloud shoes encourage a more natural running gait. The responsive pods promote a midfoot or forefoot strike, which is biomechanically more efficient than heavy heel striking. This reduces braking forces and minimizes stress on the knees and hips.
Additionally, the speedboard acts as a lever, helping the foot roll smoothly from heel to toe. This smooth transition reduces muscular effort, allowing runners to maintain pace with less perceived exertion.
Many users report feeling “lighter on their feet” and able to sustain higher speeds for longer durations. Coaches and trainers increasingly recommend cloud shoes for runners looking to improve form and reduce injury risk.
Benefits for Recovery and Joint Health
The shock-absorbing properties of cloud shoes make them ideal for recovery runs. By reducing impact forces, they allow muscles and joints to heal while still maintaining aerobic fitness.
For older athletes or those with joint issues, cloud shoes offer a protective yet dynamic option. The soft landing reduces strain on the Achilles tendon, plantar fascia, and lower back—common areas of discomfort for runners.
Physical therapists have noted that patients recovering from stress fractures or shin splints often benefit from switching to cloud shoes during rehabilitation. The combination of cushioning and support helps prevent re-injury while promoting confidence in movement.
“I’ve had knee pain for years, but since switching to Cloudflow, my long runs are pain-free. It’s like my body finally got the support it needed.” — Sarah Lin, Marathon Runner & Physical Therapist
Cloud Shoes vs. Other Performance Footwear: A Comparative Analysis
While cloud shoes have gained immense popularity, how do they stack up against other leading performance shoes? Let’s compare them to top models from Nike, Hoka, and Brooks.
Cloud Shoes vs. Nike React Infinity Run
The Nike React Infinity Run is designed to reduce injury risk with a wide base and soft foam. However, it’s significantly heavier (10.1 oz) than most cloud shoes and lacks the dynamic pod system.
While Nike’s React foam is durable, it doesn’t offer the same level of energy return as Helion™. Runners who prioritize speed and agility often find the Infinity Run too sluggish for tempo workouts.
Cloud shoes, particularly the Cloudflow, are lighter and more responsive, making them better suited for faster paces.
Cloud Shoes vs. Hoka Clifton 9
Hoka is known for maximal cushioning, and the Clifton 9 delivers plush comfort with a thick EVA midsole. It’s excellent for long-distance comfort but can feel unstable on uneven terrain.
Cloud shoes, in contrast, offer a more balanced ride. The modular pods provide cushioning where needed without the “boat-like” feel some associate with Hokas.
Additionally, cloud shoes are generally more breathable and have a more modern aesthetic, appealing to style-conscious consumers.
Cloud Shoes vs. Brooks Ghost 15
The Brooks Ghost 15 is a reliable, well-cushioned daily trainer. It’s a favorite among neutral runners for its consistent performance.
However, it lacks the innovative technology seen in cloud shoes. The Ghost relies on traditional DNA Loft foam, which compresses over time and doesn’t rebound as quickly.
Cloud shoes offer a more dynamic experience, with better energy return and a more adaptive fit. While the Ghost is a solid workhorse, cloud shoes feel more like a performance upgrade.
The Role of Cloud Shoes in Injury Prevention
Injury prevention is a major concern for runners, with over 50% experiencing an injury each year. Cloud shoes are increasingly recognized for their role in reducing common running-related injuries.
Their design minimizes impact forces, supports natural foot motion, and promotes better alignment—all critical factors in injury prevention.
Reducing Impact-Related Injuries
High-impact forces are a leading cause of stress fractures, shin splints, and joint pain. The CloudTec® system absorbs and redistributes these forces, reducing peak loading on bones and tendons.
Independent lab tests show that cloud shoes reduce vertical loading rates by up to 18% compared to standard running shoes. This means less strain on the skeletal system with every step.
For runners increasing their mileage or training on hard surfaces, this reduction can be the difference between staying healthy and getting sidelined.
Supporting Proper Biomechanics
Poor running form—such as overstriding or excessive pronation—can lead to chronic injuries. Cloud shoes help correct these issues through intelligent design.
The speedboard encourages a shorter, quicker stride, reducing overstriding. The independent pods adapt to foot roll, minimizing excessive inward or outward motion.
For runners transitioning to a more natural gait, cloud shoes act as a supportive guide, helping retrain muscle memory without the need for orthotics.
Case Studies and User Testimonials
Many runners have reported significant improvements after switching to cloud shoes. For example, a 2023 survey conducted by On Running found that 78% of users experienced fewer aches and pains within the first month of use.
One user, Mark T., shared: “I had chronic plantar fasciitis for two years. After switching to Cloudrunner, the pain disappeared in six weeks. I can finally run without fear.”
While individual results vary, the consistent feedback points to cloud shoes as a valuable tool in injury management and prevention.
