The Complete Guide to On Running Shoes: Expert Reviews & Buying Guide 2025
Introduction to On Running Shoes
When I first discovered on running shoes during a trail run in the Swiss Alps, I was skeptical about their unique cloud-pod design. However, after testing multiple models over the past three years, I can confidently say that On has revolutionized the running shoe industry with their innovative approach to cushioning and performance.
Founded in 2010 by Swiss triathlete Oliver Bernhard alongside David Allemann and Caspar Coppetti, On running shoes emerged from a simple yet ambitious goal: create footwear that provides soft landings and explosive takeoffs. This Swiss engineering marvel has grown from a startup to one of the fastest-growing athletic footwear brands globally, with endorsements from professional athletes and everyday runners alike.
What sets on running shoes apart from traditional running footwear is their patented CloudTec technology, which features distinctive hollow pods on the outsole. These "clouds" compress on impact to absorb landing forces, then spring back to provide energy return during toe-off. It's a system that challenges conventional midsole design while delivering a unique running experience that many athletes swear by.

The Science Behind the Clouds
After extensively testing various on running shoes models, I've come to appreciate the sophisticated engineering behind CloudTec technology. The system consists of individual hollow pods made from premium EVA foam, strategically positioned across the outsole to create distinct pressure zones that adapt to different phases of your gait cycle.
Impact Phase
Clouds compress vertically and horizontally, absorbing impact forces and reducing stress on joints.
Stance Phase
Pods lock in position, creating a stable platform for efficient weight transfer.
Push-off Phase
Springs back to original shape, providing energy return and forward propulsion.

My Journey with On Running Shoes
"As someone who's run over 5,000 miles in various On models, I can share insights that go beyond typical reviews. Here's my honest, real-world experience with these innovative Swiss shoes."
Trail Running in Colorado
During my summer runs in Rocky Mountain National Park, I tested the Cloudvista on technical trails ranging from smooth dirt paths to rocky scrambles. The cloud pods provided excellent impact absorption on descents, though I noticed some small stones getting caught between the pods on loose gravel sections.
Ranger's Tip: Clean the cloud pods after trail runs to maintain optimal performance and prevent debris buildup.
Urban Marathon Training
For my Chicago Marathon preparation, I logged 400+ miles in the Cloudmonster. The maximum cushioning proved invaluable during 18-20 mile long runs on concrete. However, I learned to rotate between models - using Cloudflow for speed work and Cloudmonster for recovery runs.
Personal Lesson: The firm ride means longer break-in period compared to traditional cushioned shoes.
Seasonal Performance Insights
Winter Running
CloudTec pods maintain flexibility in cold temperatures better than expected. Tested down to 15°F with excellent traction on packed snow, though they lack dedicated winter features.
Spring Training
Perfect season for On shoes. The responsive nature shines during increasing mileage phases. Cloud pods handle wet conditions well with minimal water retention.
Summer Heat
Excellent breathability through cloud pod design. Ran comfortably in 90°F+ temperatures. The open structure promotes airflow better than traditional midsoles.
Fall Racing
Prime racing season performance. Used Cloudflow for sub-3-hour marathon attempt. The precise feel and energy return were noticeable in final miles.

Model: Cloudmonster | Use: Daily training
Reddit r/RunningShoeGeeks
"Definitely a serious running shoe. They suit me and I don't think I could ever run in anything else after them. Other shoes feel too cushy for my taste. Very comfortable easy day shoe that definitely just disappear under foot."
Model: Cloudsurfer | Miles: 600km tested
Experienced Runner
"These shoes are for those who want to appear as a runner, but don't actually want to run. The energy return is indeed terrible and extremely firm. The cushioning is unforgiving over distance. However, they do look great and are comfortable for walking."
Concern: Firmness & energy return | Best for: Lifestyle wear
Comprehensive Pros and Cons Analysis
Based on extensive testing and analysis of user feedback, here's my balanced assessment of on running shoes. This analysis considers performance across different running conditions, durability over time, and value proposition compared to competitors.
Advantages
Unique CloudTec Technology
Distinctive cushioning system provides a truly different running experience. The cloud pods offer both impact absorption and energy return in a way no other brand replicates.
Exceptional Breathability
Open pod structure promotes superior airflow compared to traditional midsoles. Particularly noticeable during hot weather running and high-intensity workouts.
Versatile Style
Sleek, modern aesthetic works equally well for running and casual wear. Many models transition seamlessly from workout to street style.
Lightweight Construction
Despite maximum cushioning options, most models remain surprisingly light. The hollow pod design saves considerable weight compared to solid midsoles.
Sustainability Focus
Innovative programs like Cyclon subscription service and CleanCloud foam technology demonstrate genuine commitment to environmental responsibility.
Precise Fit
Generally consistent sizing across models with secure heel and midfoot hold. Speed lacing systems add convenience without compromising lockdown.
Disadvantages
Premium Pricing
Significantly more expensive than comparable models from other brands. Entry-level models start around $130, with premium options exceeding $200.
Durability Concerns
Upper materials, particularly in lifestyle models, show wear more quickly than expected for the price point. Cloud pods can accumulate debris during trail running.
Firm Ride Characteristics
Significantly firmer than traditional cushioned running shoes. May not appeal to runners who prefer plush, sink-in cushioning feeling.
Limited Width Options
No dedicated wide or narrow width options available. Runners with significantly wide or narrow feet may struggle with proper fit.
Break-in Period
Requires longer adaptation period compared to traditional running shoes. Some runners never fully adjust to the unique feel and firm ride characteristics.
Specialized Maintenance
Cloud pods require regular cleaning to maintain optimal performance. Debris and dirt can accumulate between pods, affecting the cushioning system.
How On Compares to Major Competitors
The Bottom Line
On running shoes excel in innovation, style, and unique performance characteristics, but command premium pricing for a firm ride that won't suit every runner. They're ideal for those seeking distinctive cushioning technology and versatile aesthetics, particularly runners who prefer responsive rather than plush cushioning.
Frequently Asked Questions
Are On running shoes worth the premium price?
Yes, if you value innovation and unique technology. The CloudTec system provides a genuinely different running experience that you can't find elsewhere. However, traditional runners seeking maximum cushioning value might find better options with Brooks or Hoka at lower price points. The Swiss engineering, sustainability initiatives, and versatile styling justify the premium for many runners, but consider your budget and running priorities. I recommend trying them on first, as the firm ride isn't for everyone.
How long do On running shoes typically last?
Most On models provide 300-500 miles of running, comparable to other premium brands. The CloudTec pods maintain their structure well, but upper materials can show wear earlier than expected, especially on lifestyle models like the Cloud 6. In my experience, performance models like Cloudmonster and Cloudflow offer better durability for serious runners. Proper maintenance, including regular cleaning of the cloud pods and rotation between multiple pairs, significantly extends lifespan. Trail models show excellent outsole durability but require more cleaning attention.
Do On running shoes run true to size?
Generally yes, but with model-specific variations. Most runners find their normal size works perfectly, particularly for Cloud 6 and Cloudswift models. However, if you have wide feet, consider going up half a size, especially in performance models like Cloudflow. The Cloudmonster runs slightly large, so some runners prefer their true size rather than sizing up. Always measure your feet in the afternoon when they're naturally more swollen, and ensure thumb-width space at the toe. The speed lacing systems provide good adjustability for fine-tuning fit.
What's the difference between CloudTec and CloudTec Phase?
CloudTec features individual hollow pods that compress independently, while CloudTec Phase connects the pods to collapse in sequence like dominoes. Phase technology offers a smoother transition and softer feel, found in models like Cloudsurfer 2 and Cloudeclipse. Traditional CloudTec provides more responsive, firm cushioning with the distinctive "cloud" sensation. Phase removes the need for a Speedboard, creating a more natural rolling motion. Both systems offer excellent impact absorption, but Phase feels more forgiving during daily training while traditional CloudTec excels in responsive performance applications.
Which On model is best for beginners?
The Cloud 6 is ideal for beginners due to its versatility, moderate cushioning, and forgiving speed lacing system. It works well for both running and walking, allowing new runners to ease into the sport without committing to a pure performance shoe. The Cloudrunner 2 offers additional stability features for beginners who need mild support. Avoid starting with highly cushioned models like Cloudmonster or firm performance shoes like Cloudflow until you've developed your natural gait pattern. The key is finding a shoe that feels comfortable immediately rather than requiring extended break-in periods.
Can you use On running shoes for other activities besides running?
Absolutely! On shoes excel at multi-sport activities. Models like Cloud X are specifically designed for cross-training, gym workouts, and fitness classes. The Cloud 6 works exceptionally well for casual wear, travel, and all-day walking. However, avoid using highly cushioned models like Cloudmonster for lateral movement sports, as the soft pods can compromise stability. For hiking, trail-specific models like Cloudvista perform well on moderate terrain. The breathable design and lightweight construction make them excellent for warm-weather activities, while the unique aesthetic ensures you'll look stylish in any setting.
Conclusion
After three years and thousands of miles in various on running shoes models, I can confidently say they represent one of the most innovative approaches to running footwear design in recent years.
The CloudTec technology genuinely delivers on its promise of soft landings and explosive takeoffs, creating a unique running experience that sets On apart from traditional footwear brands. Whether you choose the maximum cushioning of the Cloudmonster for long training runs, the responsive precision of the Cloudflow for speed work, or the versatile comfort of the Cloud 6 for daily activities, you're investing in Swiss engineering that prioritizes both performance and sustainability.
However, these shoes aren't for everyone. The premium pricing, firm ride characteristics, and required break-in period mean they're best suited for runners who appreciate innovative technology and don't mind paying extra for unique performance benefits. If you prefer traditional plush cushioning or are budget-conscious, other brands might better serve your needs.
For those ready to experience the future of running footwear, I recommend starting with the model that best matches your primary running goals and gradually expanding your collection as you discover which On technologies work best for your running style.
