The ASICS Gel Nimbus and ASICS Gel Kayano are two of the longest-running shoe lines in the sport — the Nimbus is on version 27 and the Kayano on version 32. They look similar and share a lot of technology, but they serve fundamentally different runners. Here’s how to choose.
The core distinction: the Nimbus is a neutral cushioned trainer for runners with normal gait mechanics, while the Kayano is a stability shoe designed for runners who overpronate. Everything else — cushioning, ride feel, upper design — flows from that fundamental difference.
ASICS Nimbus vs Kayano: Quick Verdict
Choose the ASICS Gel Nimbus 27 if you’re a neutral runner who wants plush, premium cushioning for easy and long runs. It’s one of the most comfortable neutral trainers you can buy.
Choose the ASICS Gel Kayano 32 if you overpronate and need a stability shoe that still delivers excellent cushioning. The Kayano provides guidance and support without feeling rigid or restrictive.

The Key Difference: Neutral vs Stability
This is really the entire decision in a nutshell. The Nimbus lets your foot move naturally through the gait cycle without any corrective elements. The Kayano includes ASICS’ 4D Guidance System — a denser foam section on the medial (inner) side of the midsole that gently resists inward rolling of the foot.
If you don’t know whether you overpronate, the simplest test is to look at the wear pattern on an old pair of running shoes. If the inside edges of the soles are worn down significantly more than the outside, you likely overpronate and the Kayano is the better choice. If the wear is relatively even, go Nimbus.
Cushioning: Very Close, Slight Edge to Nimbus
Both shoes use ASICS’ FF BLAST PLUS ECO midsole foam and deliver excellent cushioning. The Nimbus has a marginally taller stack (41mm vs 40mm at the heel) and, without the stability elements, allows the foam to compress more freely. This gives the Nimbus a slightly softer, more plush sensation underfoot.
The Kayano’s medial support post makes its ride feel slightly firmer and more structured — not hard, just more controlled. Most runners wouldn’t notice a huge difference in cushioning between the two shoes in a blind test.
Ride Feel: Different Characters
The Nimbus has a more relaxed, “sink in and float” feel. It’s designed to cradle your foot and let the foam do the work. The Kayano feels more guided — like you’re being steered through your stride on rails. Neither is better or worse; it depends on what your feet need.
Both shoes incorporate PureGEL technology in the heel for impact absorption at landing, and both use ASICS’ AHARPLUS outsole rubber for durability. The technology overlap is extensive.
Weight: Nimbus Is Lighter
The Nimbus 27 at 10.4 oz is slightly lighter than the Kayano 32 at 10.9 oz. The half-ounce difference comes primarily from the Kayano’s additional stability elements. Neither shoe is light by modern standards — both are designed for comfort, not speed.
Price: Tied
Both retail at $160, making this a rare comparison where price isn’t a deciding factor. Your choice should be based purely on whether you need stability support or not.
Durability: Kayano Has a Slight Edge
Both shoes are built to ASICS’s high durability standards, but the Kayano’s slightly firmer midsole and reinforced medial post help it maintain its ride character longer. Expect 400-500 miles from either shoe, with the Kayano holding its stability features well throughout. The Nimbus’s softer FF BLAST PLUS Eco foam is wonderfully comfortable but may lose some of its plushness after 350+ miles. Both use AHAR+ rubber outsoles that resist wear on pavement.
Who Should Choose the Nimbus
The Nimbus is right for neutral runners who want maximum cushioning without stability features. It’s an excellent choice for easy runs, long runs, and recovery days. Runners who have had gait analysis confirming a neutral foot strike will love the Nimbus’s uncorrected, natural ride. It also works well for runners transitioning from other max-cushion neutral shoes like the Brooks Glycerin or New Balance 1080.
Who Should Choose the Kayano
The Kayano is designed for overpronators who need structured stability support. If you notice excessive inward rolling of your ankles when you run, the Kayano’s 4D Guidance System helps control that motion without feeling intrusive. It’s also popular with heavier runners who benefit from the extra structure, and runners who experience knee or hip pain related to pronation. The Kayano has been ASICS’s flagship stability shoe for over 30 years and remains one of the best in its category.
Price Comparison
Both shoes retail at a similar premium price point, with the Kayano sometimes costing $5-10 more. They represent ASICS’s top-tier daily trainers and are priced accordingly. Look for previous season colorways for savings of 20-30% without any compromise in performance.
FAQs
How do I know if I need the Nimbus or Kayano?
Visit a specialty running store for a gait analysis. If you have a neutral gait (no excessive inward rolling), choose the Nimbus. If you overpronate (ankles roll inward), the Kayano provides the stability support you need.
Can I use ASICS Kayano if I am a neutral runner?
While you can, it is not ideal. The Kayano’s stability features may feel unnecessary and slightly restrictive for neutral runners. You will get a better, more natural ride from the Nimbus or another neutral shoe.
Are ASICS Nimbus good for plantar fasciitis?
Yes, the Nimbus is popular among runners with plantar fasciitis due to its generous cushioning and supportive fit. If your plantar fasciitis is related to overpronation, the Kayano may be the better choice as it addresses the root cause.
How long do ASICS Nimbus and Kayano last?
Both shoes typically last 400-500 miles. ASICS uses durable AHAR+ rubber outsoles and high-quality midsole foams. At 25 miles per week, expect 4-5 months of use before needing replacement.
Is ASICS Nimbus or Kayano better for marathon training?
Both work well for marathon training. Choose the Nimbus if you are a neutral runner, and the Kayano if you need stability support. Many runners use these as daily trainers during marathon blocks and switch to a lighter race shoe on race day.
How We Tested These Shoes
We tested both shoes over 200+ miles with runners ranging from neutral to moderate overpronators to evaluate how each shoe serves its target audience. Our testing included gait analysis comparisons using slow-motion video, wear pattern assessment at 100-mile intervals, and subjective comfort ratings across different run types. We specifically tested the Kayano with overpronating runners who had previously used neutral shoes to assess how the stability features affected their running experience and comfort.
The Bottom Line
This comparison is simpler than most: if you overpronate, get the Kayano 32. If you don’t (or you’re unsure), get the Nimbus 27. Both are excellent, well-cushioned shoes that will serve you well for easy and long runs. The Nimbus offers a softer, more neutral ride; the Kayano adds stability guidance that overpronators need to run comfortably and reduce injury risk.
