ASICS Gel-Nimbus 25 Review: Launching March, 2023
To celebrate its 25th birthday, the iconic ASICS Gel-Nimbus 25 has undergone one of its biggest transformations ever with a high-tech redesign that will satisfy both veteran and new runners alike.
Loyal fans of the Gel-Nimbus can rest easy knowing that the qualities they've come to count on from this shoe remain intact: plush cushioning, doctor-approved support, and a firm, reliable midsole. But after a few iterations that fell a little flat among the running community, the new Gel-Nimbus 25 is making an exciting comeback that places it squarely back in the running with top shoes on the market.
ASICS Gel-Nimbus 25 Specs & New Tech
Construction: Neutral daily trainer
Stack & Drop: 41.5 mm / 33.5 mm (8 mm drop)
Upper: Engineered knit upper wraps around the foot providing breathable and flexible support.
Notable Tech Features: Combined PureGEL & FF BLAST ECO PLUS technology with 20% more foam underfoot provides ample cushioning and soft-as-clouds landings.
Tester Reviews: Everything You Need To Know
In an independent study at The Biomechanics Lab in Australia, the Gel-Nimbus 25 was named "The Most Comfortable Running Shoe" by 100 active runners when compared against five other popular shoes in the study.
Still, we decided to have a few of our BlackToe Running Shoe Experts take the new Gel-Nimbus 25 through a series of training runs to generate our own feedback. Take a look at their honest reviews!
Fit, Feel, and Comfort
Jenn: "Historically I have struggled with models that fit on the narrow side, like many ASICS shoes of past, but these are not tight and have such a great fit. The upper of the shoe is very accommodating and there are NO pressure points for me: they weren’t squeezing or rubbing my 'Flintstones feet' at all. I think the new upper will have a good amount of flexibility for people who are prone to foot swelling with extra mileage.
Andrew: "I’ve been running in the ASICS Gel-Nimbus series for the past 6 years and this is by far the best iteration of the shoe that I’ve run in. The Gel-Nimbus 25 feels light years ahead of what they did with the 24! The shoe has even more support under the foot (despite being so much lighter: how did they do it?!), and it really feels like the perfect maximum cushion, every day training shoe. I’m a big fan of the additional width in the sole, which provides even more overall support."
Tania: "Wow, I've always liked the softness of the Gel-Nimbus, but the new model really offers amazing impact absorption. I think they would be very helpful for heel strikers, due to the high stack under the heel."
Sarah: "These are incredibly soft but still provide just enough rebound to make me feel like I've got some energy underfoot. I absolutely love the new upper, it's like putting your favourite sweater on: cozy, flexible, and feels like a hug. The heel has a sock-like design to it that I enjoyed. I was worried it wouldn't offer enough ankle support on long runs, but I was definitely proven wrong. It can go the distance!"
Jenn: "Even with all of the cushion and support, these shoes still felt light and springy. There are previous versions of the Gel-Nimbus that became pretty heavy, but ASICS has really rectified that with this new model."
Andrew: "The new foam blend has a nice solid feel throughout, even though there is a lot of cushioning. It's an interesting sensation between being both soft and solid, and there is a surprising amount of responsiveness to this shoe."
Tania: "These shoes are really nice for both running and walking. It's energetic enough to be a great training buddy, but I keep reaching for them when I need to walk as well. ASICS has really leaned into the 'rocker' technology across the lineup, and even though these aren't a 'performance shoe,' they still help get you onto your toes for a really smooth transition."
Sarah: "I find myself really enjoying the performance of the new Gel-Nimbus 25! It's very comfortable during easier efforts but is certainly capable of 'activating' when I add some pickups to my run, likely due to the rocker technology and new foam blend."
Who Is This Shoe Best Suited For?
Jenn: "I’m pumped to get them out for longer runs this spring and summer. As an ultra-marathoner, I take my distance shoes very seriously. These fit the bill. I also suspect they will become my go-to option for run-commuting."
Tania: "I think the Gel-Nimbus 25 will make a great addition to anyone's shoe collection as a mid-to-long distance trainer. You can use it for just about any type of casual run, and the comfort, cushion, and support makes them suitable for all neutral runners."
Andrew: "It’s the perfect shoe for city sidewalks and pavement since it takes away the rough feeling of the ground but doesn’t take away all the pop in your step. I could see these shoes being great for everything from easy recovery runs to long runs and even some quicker uptempo work."
Sarah: "It's very easy to recommend these shoes to customers because they are so versatile and comfortable. Whether you're a walker, new runner, or veteran marathoner, you could probably use these shoes in your collection. It helps that they are really stylish too!"
