On CloudFlyer 4 and ASICS Gel-Kayano 30 is their cushioning style and stability level. The CloudFlyer 4 offers a more responsive, firmer ride with moderate stability features, while the Gel-Kayano 30 provides plush, soft cushioning with stronger stability for more severe overpronators. Both are quality running shoes for different preferences.
Before comparing the specifics, here is an overview of On CloudFlyer 4 vs ASICS Gel-Kayano 30:
| Feature | On CloudFlyer 4 | ASICS Gel-Kayano 30 |
| Weight | Lighter (9.9 oz men’s) | Heavier (10.6 oz men’s) |

Summary: The CloudFlyer 4 is great if you want a lighter shoe with a responsive feel and don’t need maximum stability. The Gel-Kayano 30 is better if you need more support for your feet and love soft cushioning. The CloudFlyer looks more modern, while the Kayano comes in more width options. Both cost about the same and are good for running, but they feel different on your feet. Try them both if you can to see which one feels more comfortable for you.
What Makes a Good Running Shoe?
Before we compare these two shoes, let’s talk about what makes a good running shoe. A good running shoe should:
- Feel comfortable on your feet
- Support your feet in the right places
- Last a long time
- Let your feet breathe
- Match your running style
Now, let’s see how the CloudFlyer 4 and Gel-Kayano 30 measure up in these areas.
On CloudFlyer 4: The Basics
The On CloudFlyer 4 is made by On, a Swiss company known for its unique cushioning system. This shoe is designed for runners who need stability but still want a light, responsive feel.
The CloudFlyer 4 has On’s special CloudTec® cushioning, which uses hollow pods (called “clouds”) that compress when you land and then become firm when you push off. This gives you both comfort and energy return.
ASICS Gel-Kayano 30: The Basics
The ASICS Gel-Kayano 30 is the 30th version of this popular stability shoe. ASICS is a Japanese company with a long history of making running shoes. The Kayano line is known for giving lots of support to runners who overpronate (when your foot rolls inward too much when you run).
The Gel-Kayano 30 uses ASICS’ FF BLAST™ PLUS cushioning and GEL® technology to absorb shock and provide comfort. It also has features to help keep your foot from rolling inward too much.
Cushioning
On CloudFlyer 4
The CloudFlyer 4 uses On’s CloudTec® system with Helion™ superfoam. When you land, the “clouds” compress to cushion your step. Then they become firm to help you push off. This creates a feel that’s both soft and responsive. The cushioning is moderate—not too soft, not too firm.
ASICS Gel-Kayano 30
The Gel-Kayano 30 has ASICS’ FF BLAST™ PLUS foam and GEL® technology in the heel and forefoot. This combination makes for a very cushioned feel, especially in the heel. Many runners describe the Kayano 30 as plush and soft, offering a lot of protection from the impact of running.
Which has better cushioning?
If you want a softer, more cushioned feel, especially in the heel, the Gel-Kayano 30 might be better for you. If you prefer a firmer, more responsive feel, you might like the CloudFlyer 4 more.
Stability
On CloudFlyer 4
The CloudFlyer 4 provides stability through its wide base and Speedboard, a firm plate that runs the length of the shoe. The Speedboard helps control excess motion while still allowing for a natural stride. The CloudFlyer’s stability is more subtle than some other stability shoes.
ASICS Gel-Kayano 30
The Gel-Kayano 30 uses several technologies to provide stability. It has a firm piece on the inner side of the midsole (called LITETRUSS™) that helps prevent overpronation. The shoe also has a wide base and structured upper for added support. The Kayano provides strong stability for moderate to severe overpronators.
Which has better stability?
The Gel-Kayano 30 offers more pronounced stability features and might be better for runners who need more correction for overpronation. The CloudFlyer 4 provides more moderate stability that feels less intrusive.
Durability
On CloudFlyer 4
The CloudFlyer 4 uses durable materials, including a rubber outsole and high-quality upper. The Helion™ foam is designed to last longer than traditional EVA foam. However, some runners report that the spaces between the “clouds” can collect small rocks and debris, which might affect durability.
ASICS Gel-Kayano 30
The Gel-Kayano 30 is built to last, with ASICS’ AHARPLUS™ rubber in high-wear areas of the outsole. The upper is made of engineered mesh that holds up well over time. The Kayano line has a reputation for durability, and the 30th version continues this tradition.
Which is more durable?
Both shoes are built to last, but the Gel-Kayano 30 might have a slight edge in overall durability, especially for runners who put in high mileage.
Breathability
On CloudFlyer 4
The CloudFlyer 4 has an engineered mesh upper that provides good airflow. The mesh is lightweight and has strategically placed ventilation zones to keep your feet cool. The shoe breathes well even on warm days.
ASICS Gel-Kayano 30
The Gel-Kayano 30 also uses engineered mesh for its upper, but it’s a bit more structured than the CloudFlyer 4. While it still provides good breathability, it might not feel quite as airy as the CloudFlyer. However, the mesh is designed to adapt to your foot shape, which can improve comfort.
Which is more breathable?
The CloudFlyer 4 has a slight advantage in breathability, making it a better choice for running in hot weather.
Shoe Fit
On CloudFlyer 4
The CloudFlyer 4 has a medium-width toe box and a secure midfoot and heel. It tends to run true to size, but some runners with wider feet might find it a bit narrow. The lacing system allows for a customized fit.
ASICS Gel-Kayano 30
The Gel-Kayano 30 has a roomier toe box than previous versions. It comes in multiple widths (narrow, regular, wide, and extra-wide), making it suitable for a variety of foot shapes. The shoe has a secure heel fit to prevent slippage.
Which has a better fit?
The Gel-Kayano 30 offers more options for different foot widths, making it more versatile for a wider range of runners. However, if you have narrow to medium-width feet, either shoe could work well for you.
Comfort
On CloudFlyer 4
The CloudFlyer 4 offers a comfortable ride with its CloudTec® cushioning. The shoe has a 9mm heel-to-toe drop, which is a moderate height that works well for many runners. The upper is soft and doesn’t cause irritation. Some runners find the “clouds” create a unique feel that takes getting used to.
ASICS Gel-Kayano 30
The Gel-Kayano 30 is known for its plush comfort. It has a 10mm heel-to-toe drop, which is slightly higher than the CloudFlyer 4. The generous cushioning makes it comfortable for long runs. The upper is soft and adapts to the shape of your foot over time.
Which is more comfortable?
Comfort is very personal, but many runners find the Gel-Kayano 30 more comfortable for long distances due to its plush cushioning. The CloudFlyer 4 offers a different kind of comfort that’s more responsive and less plush.
Quality
On CloudFlyer 4
On is known for high-quality construction and attention to detail. The CloudFlyer 4 is well-made with premium materials. The stitching is neat and the overall finish is excellent.
ASICS Gel-Kayano 30
ASICS has a long history of making quality running shoes, and the Gel-Kayano 30 continues this tradition. The materials are durable, the construction is solid, and the shoe is built to withstand many miles of running.
Which has better quality?
Both shoes are high-quality products from reputable brands. The difference in quality is minimal and might come down to personal preference.
Style and Appearance
On CloudFlyer 4
The CloudFlyer 4 has a modern, distinctive look with On’s signature “cloud” pods visible on the sole. It comes in several color options, including some bright choices and more subtle ones. The Swiss design influence gives it a clean, stylish appearance that works well both for running and casual wear.
ASICS Gel-Kayano 30
The Gel-Kayano 30 has a more traditional running shoe look but with modern updates. It comes in a wide range of colors, from bold to understated. The shoe has ASICS’ iconic tiger stripes on the sides and a sleek overall design.
Which looks better?
Style is subjective, but the CloudFlyer 4 might appeal more to those who want a distinctive, fashion-forward look. The Gel-Kayano 30 has a more classic running shoe appearance that many runners prefer.
Size and Sizing
On CloudFlyer 4
The CloudFlyer 4 tends to run true to size. On recommends buying your usual running shoe size. The shoe comes in standard widths only, which might be limiting for some runners.
ASICS Gel-Kayano 30
The Gel-Kayano 30 also runs true to size for most runners. As mentioned earlier, it comes in multiple width options (narrow, regular, wide, and extra-wide), making it easier to find your perfect fit.
Which has better sizing options?
The Gel-Kayano 30 offers more sizing options with its multiple width choices, making it more versatile for different foot shapes.
Material and Construction
On CloudFlyer 4
The CloudFlyer 4 uses:
- Engineered mesh upper for breathability
- Helion™ superfoam for cushioning
- CloudTec® pods made of rubber for cushioning and traction
- Speedboard for stability and energy return
- Padded tongue and collar for comfort
ASICS Gel-Kayano 30
The Gel-Kayano 30 uses:
- Engineered knit upper that adapts to your foot
- FF BLAST™ PLUS foam for cushioning
- GEL® technology in the heel and forefoot for shock absorption
- LITETRUSS™ technology for stability
- AHARPLUS™ rubber on the outsole for durability
Which has better materials?
Both shoes use high-quality, modern materials. The CloudFlyer 4’s materials focus on responsiveness and lightweight support, while the Gel-Kayano 30’s materials emphasize plush cushioning and strong stability.
Weight
On CloudFlyer 4
The CloudFlyer 4 weighs about 9.9 oz (280g) for a men’s size 9 and 8.3 oz (235g) for a women’s size 8. This makes it a relatively lightweight shoe for a stability model.
ASICS Gel-Kayano 30
The Gel-Kayano 30 weighs about 10.6 oz (300g) for a men’s size 9 and 9.2 oz (260g) for a women’s size 8. It’s slightly heavier than the CloudFlyer 4.
Which is lighter?
The CloudFlyer 4 is about 0.7 oz (20g) lighter than the Gel-Kayano 30, which might make a difference for runners who prefer lighter shoes.
Flexibility
On CloudFlyer 4
The CloudFlyer 4 has good flexibility thanks to the spaces between the CloudTec® pods. The Speedboard provides some structure but still allows the shoe to flex naturally with your foot. The shoe bends primarily in the forefoot, where you need flexibility for toe-off.
ASICS Gel-Kayano 30
The Gel-Kayano 30 is moderately flexible. The forefoot has deep flex grooves that allow the shoe to bend with your foot. However, the shoe is somewhat stiffer in the midfoot to provide stability.
Which is more flexible?
The CloudFlyer 4 offers slightly more flexibility, which some runners might prefer for a more natural feel. The Gel-Kayano 30’s moderate flexibility provides a good balance of structure and movement.
Water Resistance
On CloudFlyer 4
The CloudFlyer 4 is not specifically designed to be water-resistant. The mesh upper will allow water to enter if you run in rain or through puddles. However, the shoe drains and dries relatively quickly.
ASICS Gel-Kayano 30
Like the CloudFlyer 4, the Gel-Kayano 30 is not water-resistant. The engineered mesh will get wet in rainy conditions. The shoe does drain well but may take some time to dry completely due to its plush cushioning.
Which handles water better?
Neither shoe has a significant advantage in water resistance. Both will get wet in rainy conditions, though the CloudFlyer 4 might dry a bit faster due to its more open mesh and lower weight.
Sole Construction
On CloudFlyer 4
The CloudFlyer 4’s sole has three main parts:
- CloudTec® pods: These hollow “clouds” compress upon landing and then become firm for toe-off
- Speedboard: A firm plate that runs the length of the shoe for stability and energy return
- Helion™ superfoam: A lightweight foam that provides cushioning and durability
The outsole uses rubber in high-wear areas for traction and durability.
ASICS Gel-Kayano 30
The Gel-Kayano 30’s sole consists of:
- FF BLAST™ PLUS foam: A soft, bouncy foam that provides cushioning
- GEL® technology: Placed in the heel and forefoot to absorb shock
- LITETRUSS™: A firm piece on the inner side that provides stability
- AHARPLUS™ rubber: A durable rubber on the outsole for traction
The outsole has a guidance line that helps promote efficient running form.
Which has a better sole?
Both soles are well-designed for stability runners but offer different experiences. The CloudFlyer 4’s sole provides a more responsive, bouncy feel, while the Gel-Kayano 30’s sole offers more plush cushioning and stronger stability features.

A running store can analyze your gait to help determine if you need stability shoes.
