Welcome to Flawless Shoe Reviews! Today, we’re comparing two of Asics’ most popular neutral running shoes: the Asics Gel Cumulus 27 and the Asics Gel Nimbus 27.
While both shoes fall into the neutral cushioned category, they are designed for different types of runners and offer unique underfoot experiences. Whether you’re looking for an everyday trainer, a long-distance option, or a shoe for all-day comfort, I’ll break down everything you need to know so you can decide which one best fits your needs.
Fit & Upper: Subtle but Important Changes
Both models feature an engineered mesh upper with a true-to-size fit, and wide versions are available for those who need extra room. However, there are some key differences:
Asics Gel Cumulus 27: Improved Fit & Comfort
- Compared to the Gel Cumulus 26, the toe box has been widened slightly, giving a more accommodating fit.
- The new padded tongue provides better comfort than the previous model’s cloth tongue.
- More padding around the heel cup gives a plush yet secure feel.
- A gusseted tongue (stitched to the sides) prevents slipping and ensures a snug lockdown.
Asics Gel Nimbus 27: More Plush & Luxurious
- More padded heel cup, creating a premium, snug feel around the ankle.
- A cloth tongue (also gusseted) adds extra softness.
- Even more toe box space, making it great for those who prefer a roomier fit.
- Overall, the Nimbus 27 prioritizes comfort over weight savings, making it perfect for all-day wear.
Midsole & Cushioning: What’s Different?
The biggest distinction between these two shoes lies in the midsole cushioning. While both use FF Blast+ foam, the Nimbus 27 incorporates FF Blast+ Eco, offering an even softer ride.
Model | Heel Stack | Forefoot Stack | Drop | Weight (Men’s US 9) |
---|---|---|---|---|
Gel Cumulus 27 | 37.5mm | 29.5mm | 8mm | 264g |
Gel Nimbus 27 | 43.5mm | 35.5mm | 8mm | 307g |
Gel Nimbus 27: Maximum Cushioning for Ultimate Comfort
The Nimbus is designed for max cushioning, making it a fantastic choice for:
- Long-distance runs where impact absorption matters.
- Walking or standing all day, thanks to its soft, plush feel.
- Recovery runs, as it provides a super comfortable, gentle ride.
Despite its plush nature, the Nimbus 27 is slightly more responsive than the Nimbus 26, making it usable for early-stage uptempo runs. However, it’s still heavier than the Cumulus and not as nimble for speedwork.

Gel Cumulus 27: A Lighter, Versatile Option
The Cumulus 27 is a lighter, more agile alternative. It’s still soft but offers a firmer underfoot feel compared to the Nimbus. This makes it ideal for:
- Daily training (easy runs, long runs, steady efforts).
- Runners who prefer a more grounded feel instead of excessive softness.
- A versatile all-around shoe that doesn’t feel overly heavy.
Stability Features: More Than Just Neutral
While both the Nimbus 27 and Cumulus 27 are classified as neutral running shoes, they incorporate stability elements that help keep your foot centred and supported.
Gel Nimbus 27 Stability Features
- Larger sidewalls around the heel provide excellent guidance.
- A broad base of support helps keep the foot stable during transitions.
- Sole flare (outwardly extended outsole) prevents excessive inward/outward rolling.
- Moderately stiff heel counter cradles the foot while maintaining comfort.
Gel Cumulus 27 Stability Features
- Sidewalls on both the medial and lateral sides help guide foot motion.
- It has a slightly wider midfoot base than the Cumulus 26, improving overall stability.
- Sole flare and broad forefoot base keep the foot aligned and supported.
While both models are stable neutral shoes, the Nimbus 27 feels softer and slightly more cushioned, whereas the Cumulus 27 provides a firmer, more controlled ride.

Use Cases: Which Shoe Is Right for You?

Final Thoughts: Which Should You Choose?
The Asics Gel Nimbus 27 and Gel Cumulus 27 are fantastic shoes, but the right choice depends on your priorities.
- If you want the softest, most cushioned ride, love max comfort, and need a shoe for long runs, recovery runs, or all-day wear, go with the Nimbus 27.
- If you prefer a lighter, slightly firmer daily trainer that still provides excellent cushioning, opt for the Cumulus 27.
Both are solid options, and Asics has done a great job refining their fit and feel in these latest versions.
