ASICS Gel-Nimbus 25 Review: A Max-Stack Daily Trainer Rebuilt From the Ground Up

The Gel-Nimbus 25 gets a completely new design with a tall 41.5mm heel, FF Blast Plus foam, and a rolling cushioned ride built for easy and recovery miles.

Introduction

The ASICS Gel-Nimbus 25 has been completely redone compared with previous versions of the shoe. The most obvious change is at the bottom: this is now technically a super max stack shoe, yet it keeps a weight that sits on the lighter end for a shoe of this size. The result is a premium daily trainer aimed squarely at runners who want maximum comfort without giving up a smooth, rolling ride.

Stack Height and Weight

The numbers tell the story of the redesign. The Gel-Nimbus 25 carries 41.5mm in the heel and 33.5mm in the forefoot, for an 8mm drop. Men’s size 10 weighs 10.2 oz, and women’s size 8 comes in at 9 oz. For a shoe with this much cushioning underfoot, that weight lands on the lighter end of the spectrum rather than in featherweight territory.

The midsole uses full-length FF Blast Plus foam with pure Gel in the rearfoot. Together they create a distinctly cushioned platform that still feels more composed than most max-stack shoes on the market.

Ride Feel and Cushioning

Out on the road, the rearfoot feels almost like a soft insole under the heel, and you settle into the rest of the foam, which is a little firmer and more distinct and, importantly, more stable. There are decent sidewalls here, but this is not a stability shoe, so runners cautious about that should be fine.

This is not a bouncy ride at all. Instead, the Gel-Nimbus 25 delivers a rolling, very cushioned and protective feel. There is a solid lateral heel bevel, and while the heel feels a little chunky at first, once you find the sweet spot for landing it feels really good, especially on long runs. The forefoot rolls forward nicely and has a decent amount of flex, though it leans fairly stiff with some toe spring, and there is a decent curve through the profile. Rolling along is really how this shoe feels.

Who the Gel-Nimbus 25 Is For

This is a premium daily training shoe that has earned its place in long-run rotation. It shines on easy and recovery efforts, where the rolling ride lets you switch off and just cruise along without thinking about your footing. Runners who have worn the Cumulus before will find the essence is the same, but the execution is very different, and it is worth trying on to feel exactly what that means.

Upper and Fit

The upper is one of the highlights in a couple of ways. The heel is very nicely cushioned, and the heel counter is stiff, which is worth noting for runners sensitive in that area, but there is plenty of padding around it. The midfoot is slightly wider, and the forefoot tapers, so runners who want a more snug forefoot will like this fit. Runners with a wider forefoot should note that the upper does stretch, but a little caution is warranted there.

Durability

Durability has been phenomenal. After 60 miles on a test pair, there is barely a dent in the outsole, which suggests the Gel-Nimbus 25 should hold up well as a high-mileage daily trainer.

Things to Consider Before Buying

The heel does feel a little chunky until you find your landing sweet spot, and the forefoot taper may not suit runners who prefer a wider toe box, even though the upper stretches somewhat. The ride is cushioned and rolling rather than bouncy, so runners chasing a springy, energetic feel should look elsewhere.

Buying Advice

If your running is built around easy miles, long runs, and recovery days, the Gel-Nimbus 25 makes a compelling case. It pairs genuinely tall cushioning with a weight that does not punish you, wrapped in a comfortable upper that suits most daily training. Try it on first, especially if you have a wider forefoot, but for the right runner this is an easy recommendation.

Conclusion

The ASICS Gel-Nimbus 25 is a total redesign that lands as a premium, protective daily trainer. With a 41.5mm heel, FF Blast Plus foam throughout, pure Gel in the rearfoot, and a rolling cushioned ride, it is built for runners who want to switch off and enjoy the miles. Add in standout durability and a comfortable, well-padded upper, and it stands out as one of the more complete max-cushion daily trainers available.
