Asics GEL-Nimbus 27 Complete Review

It feels like we were just talking about the big Nimbus 25 overhaul, when Asics turned a classic daily trainer into a maximalist beast. Now we’ve got the Asics GEL-Nimbus 27, and honestly, the changes feel more settled and intentional. If you’ve followed this line, you know the whole point has always been comfort. The real question is whether the 27 actually moves the needle, or if it’s mostly a refresh of the same ride.

Quick Take

Overall Rating: 4.4/5

Best For: Easy runs, Recovery days, Long slow distance, Heavy runners, Walkers

Key Strengths: Luxurious "cloud-like" cushioning, significantly improved breathability (goodbye to the hot knit!), stable neutral ride, exceptional outsole grip

Notable Limitations: A bit heavy/clunky for speed work, exposed midsole foam might worry trail runners, price has ticked up slightly in some regions

Visual Snapshot Summary

What Makes Asics GEL-Nimbus 27 Stand Out?

When you buy a Nimbus, you’re not buying it to feel the ground. You’re buying it to forget the ground exists. The GEL-Nimbus 27 sticks to that mission, but it tightens up a few details in a way a lot of runners will appreciate.

The big story is the refined FF BLAST™ PLUS ECO foam paired with the new Engineered Jacquard Mesh upper. The Nimbus 26 was plenty cushioned, but that knit upper could run warm. Asics swapped it for a lighter, more breathable mesh that still wraps the foot securely.

What’s impressive is how stable it stays at this height. With a stack this tall (43.5mm in the heel for men!), you’d expect wobble. But the wider base and smart geometry keep the ride surprisingly steady for a neutral shoe. One reviewer summed it up well: a "luxurious, cloud-like cushioning experience that effectively absorbs impact". That sense of luxury is what separates it from a typical daily trainer.

Real Customer Experiences

Since the shoe dropped in early 2025, feedback from early adopters and reviewers has been steady. The tone is overwhelmingly positive on comfort, with the usual caveats around weight.

• ** The "Ahhh" Factor:** Almost every user mentions the immediate step-in comfort. The term "cloud-like" gets thrown around a lot, but in this case, it seems justified by the sheer volume of foam and the OrthoLite X-55 sockliner.
• Heat Management: A major point of relief for long-time fans is the upper. Users are noticing that their feet aren't overheating as much as they did in the Nimbus 26, thanks to that switch to jacquard mesh.
• The Weight Debate: While nobody expects a max-cushion shoe to be a feather, some runners do note that it feels a bit "blocky" or "bulky" when they try to pick up the pace. It's definitely a cruiser, not a racer.

What people are saying:

"The shoe excels primarily at easy to moderate paces... providing a luxurious, cloud-like cushioning experience."

"The new engineered jacquard mesh... significantly improves breathability compared to the previous knit upper, addressing concerns about warmth."

Design and Build Quality

The construction is where the Nimbus 27 justifies the price tag.

Upper: A Breath of Fresh Air

The big story is the Engineered Jacquard Mesh. It moves away from the stretchy knit of the last version. Knit looks great, but it traps heat. This mesh is lighter, soft, and made with at least 75% recycled content. It locks the midfoot down without feeling overly restrictive. You also get a stretchy knit tongue and a seriously plush heel collar that hugs the ankle.

Midsole: The Marshmallow Core

The midsole uses FF BLAST™ PLUS ECO foam, which is about 20–24% bio-based (sugar cane derived). They added 2mm of stack compared to the 26, bringing the heel to a towering 43.5mm (Men). Deep in the heel sits PureGEL™ technology. You can’t see it like the old-school Gel windows, but you’ll feel it. It’s lighter and softer than traditional gel, built to absorb shock on heel strike.

Outsole: Grip for Days

Asics didn't skimp here. They use HYBRID ASICSGRIP™, which is a mashup of their grippy rubber and their durable AHARPLUS™ rubber in high-wear zones. The traction is generally fantastic, even on wet roads. However, there are significant cutouts to save weight, which exposes the soft midsole foam. If you run on gravel, you might chew that foam up a bit.

Weight and Durability

It weighs around 305g (10.7 oz) for a US Men's 9. That’s not light. It’s a cruiserweight. The trade-off is durability: the outsole rubber is hard (measured at 89.4 HC durometer), so it’s built to last for hundreds of miles.

Comfort and Fit

If you’re looking at a Nimbus, comfort is probably priority number one. The GEL-Nimbus 27 delivers that in a big way.

Sizing and Width

Good news for the wide-footed runners among us: Asics continues to be generous. The shoe generally fits True to Size (TTS). But here is the kicker—the toe box is noticeably roomier than the Nimbus 26. If you felt cramped in the last version, you'll likely feel a sense of relief here. They offer multiple widths:

• Men: Standard (D), Wide (2E), Extra-Wide (4E).
• Women: Narrow (A), Standard (B), Wide (D).

The Break-in Period

Some shoes feel stiff straight out of the box. This one is mostly ready to go, but a few users mention a short “get to know you” phase. Think 10 to 50 miles for the heel cushioning to soften and mold to your stride. One reviewer said it took about 50 miles for a toe-guard pressure point to disappear, so don’t panic if mile one feels a little different.

"The highly padded heel collar provides a secure hold, resulting in excellent heel lock with no reported tongue slippage."

Style and Versatility

Let's talk aesthetics. The maximalist trend isn't going anywhere, and the Nimbus 27 embraces that "chunky" look. It's got a thick sole and a boxy shape that actually vibes pretty well with the current "dad shoe" or "gorpcore" trends seen in lifestyle sneakers.

Is it just for running? Surprisingly, no. Because of that stable platform and plush feel, this shoe is actually a killer option for:

1. Nurses or Retail Workers: Anyone standing on concrete all day will appreciate the stack height.
2. Casual Office Wear: If your workplace is chill, the sleek new colorways can pass as "tech-casual".
3. Walking: It's arguably one of the best walking shoes on the market due to the rocker geometry.

However, don’t use these for CrossFit or lateral gym movements. The stack is way too high, and you’re asking for an ankle roll.

Quality and Durability

At this price, you want the shoe to last. The consensus is that the Nimbus 27 is a “high-mileage workhorse”.

• Praise for Longevity: The outsole rubber is tough. Like, really tough. Reviewers are projecting 700-800 km (approx. 450-500 miles) of life out of these, which is above average for soft daily trainers. The foam also seems resilient; it doesn't bottom out or go "dead" quickly.
• Common Issues: The main vulnerability is cosmetic. Because of the weight-saving cutouts in the rubber, the exposed midsole foam will get scuffed and dirty if you run on anything other than pristine asphalt. It won't necessarily ruin the ride, but it might look beat up underneath. Also, watch out for that lace slippage—some found the laces a bit slippery, so double knotting might be mandatory.
