If you have visited a running store lately you have probably heard people talking about “technology. In the world of high-performance shoes “walking on clouds” is what everyone wants. However two big brands, ASICS and On Running have ideas about what a cloud should feel like.
ASICS has a technology called PureGEL. This is an light material that helps absorb shock when you run. It’s not like the gel windows in ASICS shoes, which were heavy and felt mushy. PureGEL is 65% softer and much lighter. Its placed inside the midsole of the shoe under the heel to help with impact.
ASICS Cloud Technology also uses FF BLAST foam. This foam gives the shoe a bouncy feel. When you put PureGEL and FF BLAST together you get a shoe that feels soft and springy.
On Running has an approach. They use something called CloudTec, which is made up of tubes of foam. When you land on the ground these tubes. Then lock into place. This helps with cushioning.
Here are the main differences between ASICS Cloud Technology. On Running:
- Structural vs. Material Cushioning: ASICS uses materials like gel and foam to create a cushioned ride. On Running uses tubes to absorb impact.
- The Feeling of the Transition: ASICS shoes feel smooth and consistent from heel to toe. On Running shoes feel firmer and more snappy.
When it comes to stability ASICS Cloud Technology is often paired with a system called 4D GUIDANCE SYSTEM. This helps with stability and support. On Running uses a plate called Speedboard to help with stability.
In terms of durability ASICS Cloud Technology is different from On Running. ASICS shoes don’t pick up debris like rocks or gravel. PureGEL is also very resilient. Doesn’t lose its bounce quickly.
Understanding ASICS Cloud Technology is important if you’re thinking of buying a pair of shoes. It’s different from On Running. It can help you make a better decision. ASICS Cloud Technology is, about providing a soft and springy ride. ASICS. Ff BLAST work together to create this ride. ASICS shoes feel smooth and consistent. They provide great stability and support.
Choosing Your Ride: Which “Cloud” is For You?
| Feature | ASICS (PureGEL/FF BLAST) | On Running (CloudTec) |
| Best For | Long, slow recovery runs; high mileage. | City style; HIIT workouts; fast intervals. |
| Surface | Road, light paths. | Road, gym floors, urban environments. |
| Weight | Slightly heavier due to plush padding. | Generally ultra-light. |
| Step-in Comfort | Instant “pillowy” feel. | Firm at first, softens as you move. |
When to choose ASICS Cloud Technology:
If you are training for a marathon and your joints feel the “pavement pounding,” the ASICS Cloud Technology in the Gel-Nimbus or Gel-Cumulus series is likely your best bet. It prioritizes protection and comfort over “ground feel.”
When to choose On Running:
If you value a shoe that looks as good with jeans as it does on a 5k run, or if you prefer a “firmer” cloud that lets you feel a bit of the road for better agility, On Running’s geometry-based system is the winner.
The Verdict on the “Cloud” Wars
As we move through 2026, the gap between these two brands is narrowing. On Running is moving toward “Phase” technology which looks more like traditional foam, and ASICS is making their shoes lighter and more “lifestyle” friendly.
However, the core truth remains: ASICS Cloud Technology is about material science (PureGEL), whereas On Running is about structural engineering.
If you want a traditional, plush, “hug-your-foot” experience that has been refined over 40 years, ASICS is your home. If you want a modern, firm, and aesthetically striking ride that excels in bursts of speed, On Running is the way to go.
Summary of Key Takeaways:
- ASICS Cloud Technology is officially PureGEL combined with FF BLAST foam.
- It is 65% softer than previous Gel versions.
- On Running uses hollow “Cloudpods” for mechanical cushioning.
- ASICS generally offers a smoother, more “bottomless” cushion for long-distance protection.
