In Summary: When choosing between On Cloud X3 and On Cloud Ad shoes, think about what activities you do most. If you need one shoe for school, sports, and hanging out, the X3 is your best bet.
It lasts longer and works for many different movements. If you love running and want a super light shoe just for that, pick the Ad. Both shoes have the special Cloud cushioning that feels bouncy, but they’re designed for different purposes.
Brand Background
The On Cloud Story
On Cloud started in Switzerland in 2010. Three friends had a cool idea – what if running could feel like you’re running on clouds? They created special cushioning pods for the bottom of their shoes, which they called “CloudTec.”
These hollow pods squish when you step down and spring back when you lift your foot. Today, On Cloud makes many different shoe models for all kinds of activities.
X3 and Ad Models: What’s the Difference?
The On Cloud X3 is designed for versatile training and everyday wear. It’s built to handle different activities, from running to gym workouts to walking around town. The On Cloud Ad is more specialized for road running and focuses on providing a smooth, fast experience for runners. Both use the CloudTec system, but in slightly different ways.
Comfort: How They Feel On Your Feet
On Cloud X3 Comfort
The X3 feels cushioned and supportive right out of the box. It has extra padding around the ankle and tongue, which makes it comfortable for all-day wear. The X3’s CloudTec pods are arranged to give good support whether you’re walking, running, or doing other activities.
“I can wear my X3s all day at school and then go straight to soccer practice without changing shoes,” says Jamie, age 13. “They never hurt my feet even after a whole day.”
On Cloud Ad Comfort
The Ad is designed with runners in mind. It has a more streamlined feel with targeted cushioning where runners need it most.
The heel has extra CloudTec pods to absorb impact when your foot strikes the ground. The Ad might not feel as plush as the X3 at first, but many runners say it feels amazing once you start moving.
Cushioning: The Science Behind Each Step
X3 CloudTec System
The X3 uses the CloudTec cushioning system with pods arranged for all-around performance. The pods are positioned to support different foot movements and activities. They provide a balanced feel – not too soft, not too firm. This makes the X3 good for people who do many different activities in their shoes.
Ad CloudTec System
The Ad features CloudTec pods that are optimized specifically for forward motion (running). The pods are larger in the heel for impact absorption and smaller in the forefoot to help you push off and move forward efficiently. This design helps make running feel smoother and more energetic.
Shoe Fit: Finding Your Perfect Size
X3 Fit Profile
The X3 has a medium width with slightly more room in the toe box (where your toes go). This gives your toes space to spread out naturally, which is good for balance and comfort. The heel cup is snug to keep your foot stable. Most people find the X3 fits true to size.
Ad Fit Profile
The Ad has a more performance-oriented fit that’s slightly narrower, especially in the midfoot. This snugger fit helps keep your foot secure during faster movements like running. Some people with wider feet might want to go up half a size in the Ad.
Durability: How Long Will They Last?
| Model | Average Lifespan | Best For | Weak Points |
| On Cloud X3 | 400-600 miles | Mixed activities, everyday wear | Upper material may show wear at flex points |
| On Cloud Ad | 300-500 miles | Road running, speed training | Outsole may wear faster with non-running use |
| Regular use | 8-12 months | Daily wear | Cushioning compression over time |
| Occasional use | 12-18 months | Weekend activities | Midsole stiffening with age |
X3 Durability
The X3 is built to handle different activities and surfaces, which means it has reinforced areas in spots that typically wear out first. The rubber outsole covers more of the bottom of the shoe to protect the CloudTec pods. Most X3 wearers report getting 400-600 miles or 8-12 months of regular use before needing a new pair.
Ad Durability
The Ad focuses on being lightweight for running, which means it uses less rubber on the outsole to save weight. This can make it wear out a bit faster if you use it for activities other than running. The CloudTec pods on the Ad might show wear sooner if you do a lot of sideways movements. Typically, the Ad lasts 300-500 miles for runners.
Breathability: Keeping Your Feet Cool
X3 Breathability
The X3 uses engineered mesh in the upper that allows good airflow. The mesh has different densities – more open in areas where your foot gets hot and more closed in areas that need support. This balanced approach keeps your feet from getting too sweaty while still providing structure.
Ad Breathability
The Ad features a lightweight, highly breathable mesh designed specifically for running. It has larger ventilation zones across the top of the foot and less overlapping material. This makes the Ad excellent for hot weather running, but it might feel a bit chilly in cold conditions.
Stability: Keeping You Steady
X3 Stability Features
The X3 provides good all-around stability for different movements. It has a wider base than many running shoes, which helps prevent wobbling. The midsole (the foam layer between your foot and the ground) extends up the sides of the shoe slightly to cradle your foot and provide extra support during side-to-side movements.
Ad Stability Features
The Ad focuses on forward stability for running. It has a more traditional running shoe profile with a slimmer midsole. The heel is designed to guide your foot through a smooth heel-to-toe transition when running. While great for running in a straight line, it provides less support for quick direction changes.
Quality: What Are You Getting For Your Money?
X3 Quality Details
The X3 shows excellent attention to detail in its construction. The stitching is clean and reinforced in high-stress areas. The materials feel premium, and the different parts of the shoe are connected securely. The X3 uses slightly thicker, more durable materials in areas that typically wear out first.
Ad Quality Details
The Ad uses lightweight, performance-focused materials throughout. While still high quality, these materials prioritize weight savings and speed over maximum durability. The craftsmanship is excellent, with precision stitching and thoughtful design elements that enhance running performance.
Style: Looking Good While Staying Active
X3 Style Options
The X3 has a versatile, athletic look that works well for both sports and casual wear. It comes in a wide range of colors, from bright combinations to more subtle, everyday options. The X3’s design isn’t as obviously “techy” as some On Cloud models, making it blend in better with regular clothes.
Ad Style Options
The Ad has a sleeker, more performance-oriented appearance with a distinctive running shoe silhouette. The visible CloudTec pods and streamlined upper give it a fast, modern look. The Ad typically comes in more vibrant color options that stand out. It definitely looks like a running shoe rather than a casual sneaker.
Materials: What Are These Shoes Made Of?
| Component | On Cloud X3 | On Cloud Ad | Benefits |
| Upper | Engineered mesh with reinforced zones | Lightweight performance mesh | Breathability, durability |
| Midsole | Helion superfoam with CloudTec | Helion superfoam with CloudTec | Cushioning, energy return |
| Outsole | Rubber coverage in high-wear areas | Strategic rubber placement for weight saving | Traction, protection |
| Sockliner | Memory foam | Thin performance foam | Comfort, response |
| Laces | Standard flat laces | Thin speedlaces | Security, convenience |
X3 Materials
The X3 uses a durable engineered mesh upper with strategic overlays for support. The midsole features On’s Helion superfoam combined with CloudTec pods for cushioning. The outsole has rubber placed in areas that typically wear out first. Inside, a memory foam sockliner provides extra comfort.
Ad Materials
The Ad uses an ultralight performance mesh in the upper with minimal overlays to save weight. It has the same Helion superfoam and CloudTec system, but with pods optimized for running. The outsole uses less rubber, strategically placed only where most needed. The thinner sockliner emphasizes responsiveness over plushness.
Weight: How Heavy Are They On Your Feet?
X3 Weight Profile
The X3 typically weighs about 9-10 ounces (255-285 grams) per shoe in a men’s size 9. This puts it in the mid-range for training shoes – not the lightest, but definitely not heavy. The weight is distributed evenly throughout the shoe, giving it a balanced feel.
Ad Weight Profile
The Ad is lighter, usually weighing around 7-8 ounces (200-230 grams) per shoe in the same size. This lighter weight is noticeable when running longer distances or at faster speeds. The weight is focused more toward the back of the shoe, helping your foot roll forward naturally when running.
Flexibility: How They Move With Your Feet
X3 Flexibility
The X3 offers moderate flexibility. It bends well at the forefoot (where your foot naturally bends when walking or running) but provides some stability through the midfoot. This balanced approach makes it good for different movements while still giving some support.
Ad Flexibility
The Ad is designed to be more flexible in the forefoot to promote a natural running stride. The midsole has specially designed flex grooves that help the shoe bend where your foot wants to bend during the running motion. The midfoot is slightly stiffer to help with energy transfer when pushing off.
Water Resistance: Staying Dry In Wet Conditions
X3 Water Resistance
The X3 has basic water resistance that can handle light rain and morning dew. The upper material has been treated with a water-repellent coating that causes water to bead up and roll off rather than soaking through immediately. However, in heavy rain or puddles, your feet will eventually get wet.
Ad Water Resistance
The Ad offers minimal water resistance, prioritizing breathability and quick-drying properties instead. The lightweight mesh will let water in during rainy conditions, but it also dries very quickly. On does make waterproof versions of some of their shoes (usually labeled “Waterproof” or “Weather”) if you need more protection.
Sole: What’s Under Your Feet?
X3 Sole Design
The X3 sole features CloudTec pods arranged for versatile movement. The pods are positioned to support both forward motion and side-to-side movements. The rubber outsole covers more of the bottom of the shoe for better traction on different surfaces. The X3 also has a moderate toe spring (upward curve at the front) to help with smooth transitions.
Ad Sole Design
The Ad sole is optimized for running efficiency. The CloudTec pods are larger in the heel for impact absorption and arranged in a more linear pattern to promote forward movement. The outsole has less rubber to save weight, with it placed only in high-wear areas. The toe spring is more pronounced to help roll through your stride.
Price Comparison: What Will They Cost?
| Model | Regular Price | Sale Price | Kids’ Version |
| On Cloud X3 | $140-$160 | $110-$130 | $100-$120 |
| On Cloud Ad | $150-$170 | $120-$140 | Not available |
| Entry models | $120-$140 | $90-$110 | $80-$100 |
| Premium models | $170-$200 | $140-$160 | Not available |
The X3 typically costs between $140-$160, while the Ad is priced slightly higher at $150-$170. Both represent a premium price point compared to many other athletic shoes. On Cloud sometimes has sales that can bring the price down 20-30%, usually at the end of a season or when new models are released.

Frequently Asked Questions
Can I use the On Cloud X3 for running?
Yes! The X3 works well for running, especially if you’re a casual runner who does other activities too. If you run more than 15-20 miles per week or are training for races, you might prefer the more running-specific Ad model.
Is the On Cloud Ad good for gym workouts?
The Ad can work for basic gym workouts, but it’s not ideal for exercises with lots of side-to-side movements. The X3 would be a better choice if you do activities like basketball, tennis, or fitness classes that involve jumping in different directions.
Do On Cloud shoes run true to size?
Most On Cloud shoes, including the X3 and Ad, run fairly true to size. However, the Ad has a narrower fit, so if you have wider feet or like more toe room, you might want to go up half a size. The X3 fits more true to size for most foot shapes.
How do I clean my On Cloud shoes?
For both models, remove the laces and insoles first. Wash them with mild soap and cool water using a soft brush or cloth. Don’t put On Cloud shoes in the washing machine or dryer, as this can damage the CloudTec pods and cushioning. Let them air dry away from direct heat or sunlight.
Are these shoes good for kids with flat feet?
The X3 provides more overall support and could be better for kids with flat feet. It has a wider base and more structured midsole. If you have flat feet or need extra support, you might want to add your own insoles for even more support. When in doubt, check with a doctor or footwear specialist.
