Welcome to Flawless Shoe Reviews! Today, we’re comparing two of ASICS’ most popular running shoes: the Gel Nimbus 27 and the Gel Kayano 31. While both are known for their comfort and cushioning, they serve very different purposes. In this review, we’ll break down the key features of each shoe and highlight how they’re designed to support different types of runners and medical conditions.
Specs Comparison: Gel Nimbus 27 vs. Gel Kayano 31
| Feature | ASICS Gel Nimbus 27 | ASICS Gel Kayano 31 |
|---|---|---|
| Stack Height (Heel/Forefoot) | 43.5mm / 35.5mm | 40mm / 30mm |
| Heel-to-Toe Drop | 8mm | 10mm |
| Weight (Men’s Size 9) | 307g | 311g |
| Cushioning | FF Blast+ Eco (soft, responsive) | FF Blast+ with PureGel (plush) |
| Stability Features | Mild sidewalls, broad base, sole flare | 4D Guidance System, sidewalls, sole flare |
Fit and Upper Features
Both the Nimbus 27 and Kayano 31 feature engineered mesh uppers for a comfortable, breathable fit. The Nimbus 27 has a slightly wider forefoot in its standard version and also comes in wide and extra-wide options, making it a versatile choice for a variety of foot shapes. Similarly, the Kayano 31 accommodates wider feet with its available widths and offers a slightly more padded gusseted tongue for added comfort.
Both shoes offer a true-to-size fit, but the Kayano’s heel counter is noticeably stiffer. While this adds extra stability, it might be less comfortable for those with conditions like Haglund’s deformity or insertional Achilles tendonitis. The Nimbus 27, with its moderately stiff heel counter, provides a more forgiving fit for sensitive heels.
Cushioning and Stability
ASICS Gel Nimbus 27
The Nimbus 27 uses FF Blast+ Eco cushioning, which provides a soft yet responsive feel underfoot. With its 43.5mm stack height in the rearfoot and 35.5mm in the forefoot, the Nimbus has an 8mm heel-to-toe drop. The slightly lower drop compared to the Kayano makes it feel less aggressive during transitions, and the cushioning gives a cloud-like feel, especially during walking or recovery runs.
The Nimbus also includes mild sidewalls, broad base support, and sole flare, offering subtle stability without feeling intrusive. This makes it ideal for those seeking a stable neutral shoe that’s comfortable for longer runs, standing, or walking all day. Similar Shoes to the Nimbus 27 include the Bondi 9 and the 880 V15.
ASICS Gel Kayano 31
In contrast, the Kayano 31 is a max stability shoe designed for runners who overpronate or need added support. It features FF Blast+ cushioning with PureGel in the heel for a plush, shock-absorbing experience. Its 4D Guidance System includes a dense tab under the arch that resists excessive inward motion (pronation) and guides the foot through a stable gait cycle.
With a stack height of 40mm in the rearfoot and 30mm in the forefoot, the Kayano has a 10mm drop. This slightly higher drop can help offload the Achilles tendon and make the shoe feel more supportive. Additional stability features include larger sidewalls around the heel, broad base support, and pronounced sole flare, all of which keep the foot centered and secure.
Performance and Use Cases
Both shoes are excellent for recovery runs, easy runs, and long runs, but they differ when it comes to versatility:
- Nimbus 27: This shoe transitions a bit quicker due to its slightly firmer midsole and lighter weight (307g). It’s suitable for runners looking to mix in some early-stage uptempo work or who prefer a more responsive feel during their runs. Additionally, it’s a great lifestyle shoe for walking and standing all day.
- Kayano 31: Weighing slightly more at 311g, the Kayano’s extra cushioning and stability features make it better suited for runners who overpronate or need a shoe for longer, steadier efforts. However, it’s less responsive and not ideal for faster paces or uptempo workouts. If you’re looking for a faster stability shoe, consider the Hoka Arahi 7.
Final Thoughts
The ASICS Gel Nimbus 27 is a versatile stable neutral shoe with a soft, responsive feel that works well for a variety of activities, from recovery runs to lifestyle use. The Gel Kayano 31, on the other hand, is a max stability shoe designed to provide robust support and comfort for overpronators or those needing extra guidance during their runs.
If you’re deciding between these two models, consider your specific needs:
- Choose the Nimbus 27 if you want a stable neutral shoe that’s comfortable, slightly lighter, and better suited for some faster-paced work.
- Opt for the Kayano 31 if you need maximum stability, particularly for overpronation or conditions requiring additional support.
