Product Information

Full details

The ASICS Gel-Nimbus 27 is a premium neutral running shoe designed for adult runners seeking maximum comfort and impact protection during high-mileage training. By combining advanced PureGEL technology with FF BLAST PLUS ECO cushioning, the shoe offers a plush, cloud-like experience that excels on long-distance road runs; however, its emphasis on soft cushioning means it may feel less responsive for runners prioritizing explosive speed or track work.

FAQs

Is the Gel-Nimbus 27 suitable for flat feet?

Yes, as a neutral trainer, it provides a stable platform; however, if you require specific arch support, the removable sockliner allows for the easy insertion of custom orthotics.

How often should I replace these shoes?

Generally, running shoes like the Gel-Nimbus 27 should be replaced every 400 to 500 miles, depending on your running surface and gait style.

Can I use these for gym workouts?

While they are excellent for running and walking, their soft, high-cushion platform may feel unstable during heavy weightlifting or lateral-movement-heavy HIIT classes.

Are these shoes waterproof?

No, the engineered jacquard mesh is designed for breathability and will allow water to pass through if submerged or in heavy rain.

What is the difference between the Nimbus and Cumulus series?

The Nimbus series is typically the top-tier, maximum-cushioned option, while the Cumulus series offers a slightly firmer, more versatile ride for everyday use.

Troubleshooting

Upper mesh feels too tight across the forefoot

Try a different lacing technique, such as skipping the eyelets in the tightest area to allow more volume in the toe box.

Heel slippage while running

Use the extra top eyelet to create a runner's loop (lace lock) to secure the heel more firmly against the collar.

Pros and Cons

Pros

  • Exceptional impact protection for joints
  • Breathable and comfortable upper construction
  • Secure lockdown with the gusseted tongue
  • Eco-conscious foam materials
  • Stable platform for neutral runners

Cons

  • Heavier than lightweight racing flats
  • High stack height may feel unstable on uneven trails
  • Not optimized for high-intensity interval speed training

Setup, Compatibility & Care

To ensure the longest lifespan for your Gel-Nimbus 27 trainers, always untie the laces before removing the shoes to protect the heel counter and the internal collar construction. If you use custom orthotics, the factory sockliner is removable; ensure your inserts are flat and properly aligned with the heel cup. For cleaning, avoid the washing machine, which can degrade the foam properties. Instead, wipe the jacquard mesh with a soft, damp cloth and mild soap. Allow the shoes to air dry naturally away from direct heat sources like radiators or sunlight, as high temperatures can warp the midsole cushioning materials.
