MEAGHAN: Last year I was invited to join the Asics wear testing program for the Gel-Nimbus 25. Of Asics models, the Nimbus has never been my favorite, but the substantial updates had me intrigued. And when I say substantial updates, I’m really talking about a complete overhaul of this shoe.
My favorite update is probably the Gel placement… it’s still in there, but no longer visible. Which is a good thing: Gel hasn’t been cool since Lisa Frank made it work with pens. The midsole, which was previously Flytefoam and Flytefoam Blast+ has been replaced with FF Blast+ Eco, which is made with 20% bio-based material. It’s the same stuff that’s found in Novablast 3 and Glideride 3 but with more recycled goods.
The stack has increased by 4 mm in the heel and 6 mm in the forefoot which leaves you with 41.5 mm / 33.5 mm overall stack (8 mm drop). To keep the updates going, the outsole has a completely new material to provide a softer feel. Asics Lite rubber is found beneath the forefoot with AHAR+ in the heel for added durability.
The new knit upper (previously engineered mesh) is designed with an extended knit around the collar and heel tab to provide a unique look, but also give you that plush step-in feel. What hasn’t changed? That amazing tongue from the Nimbus 24 (though it’s shorter this year, which is a good thing). Not to get weird, but it’s the best tongue on the market.
THOMAS: If one shoe’s evolution highlights how far Asics has come as a brand in the past five years, it’s the Gel-Nimbus 25. When the Nimbus of old showed up, I’ll admit– I did not want to review it. The dusty legend was passed to other reviewers to cover. Basically, it was a dull clunky shoe that podiatrists would recommend to walkers. Each year Asics made slight adjustments, emphasis on slight.
A couple years ago Asics introduced the Gel-Nimbus Lite alongside the traditional Nimbus; the shoe was basically a way to introduce the consumer to a new direction for the Nimbus, without forcing them to go cold turkey.
Long story short, life evolves, selection is natural, and the Nimbus 25 is the melding of the Nimbus and Nimbus Lite into one shoe. The days of passing the Nimbus onto others to review has ended (sorry kids), because Asics has transformed this shoe into a fantastic highly-cushioned, stable, daily trainer that lives up to the title of legend.
ROBBE: Thomas ain’t lying about passing the whole “passing the Nimbus off to other reviewers.” For awhile, we straight up didn’t even review the shoe, and then Wide Foot Jarrett and I bore its weight for a couple versions. And now Thomas reaps the benefits of us giving Asics hell through our own personal valleys of death. It’s good to be king.
For those not familiar, for years, Asics was dead in the water with the Nimbus. Aside from being the most boring daily trainer in running, from 2008-2019, the Gel-Nimbus also managed an annual podium for the “Best Shoe Your Dad Would Wear To Look Hip” award, tied only with its Kayano counterpart, and coming in second only to the Nike Air Monarch. Brooks and Mizuno fought hard to get that title in their hands, but they managed to pull it off over the last couple years.
Then the Asics Gel-Nimbus 24 right-hooked me and became one of my personal favorites of 2022, and probably the shoe I put the most miles in. The shoe was lighter, the Gel was less obvious, it actually looked not bad, and… it was just a really good shoe overall.
Nevertheless, it still had the hallmarks of a Gel-Nimbus, because for nearly a quarter century, the Nimbus was always the Nimbus. Until now. Because everything has changed.
