Asics Gel-Nimbus 26 Vs Asics Gel-Nimbus 25: I’ve Tested Both And I’d Get The Older Shoe In The Sales

The Asics Gel-Nimbus 25 was a major update for the long-running Asics Gel-Nimbus line, with Asics increasing the midsole stack height and changing the foams used to make it a more comfortable shoe than ever. I rated it among the best cushioned shoes and didn’t expect Asics to make sweeping changes with the Gel-Nimbus 26. On paper the minor updates look good: the 26 has a new outsole material to improve its grip and the upper has been adjusted to create a more secure fit around the midfoot.

However, having run 40-50 miles in both sets of shoes, as well as doing a short run with one on each foot, I can’t say that the changes have improved the shoe. I found the Gel-Nimbus 25 a little slippery on greasy paved surfaces in my first couple of runs in it, but after that the outsole roughed up a little and I had no grip concerns when running on asphalt.

The fit of both shoes in my usual running shoe size was equally good for me. Both are comfortable and great for long and easy runs, with a smooth and soft ride that helps you to tick over at relaxed paces. It’s one of the best marathon running shoes thanks to the way it helps you roll through long distances.

Given how similar the shoes are, the improved grip on the Gel-Nimbus 26 should make it a better shoe, yet the added traction doesn’t come without drawbacks. I found the outsole material on the 26 felt harder than the rubber on the 25, which made the ride “slappier” because the impact of the shoe on the sidewalk felt harder, and was louder.

I also noticed forefoot discomfort with the newer shoe when I did a fast intervals session in it, and the ride was a little less comfortable than the 25 on long runs as well. The Gel-Nimbus 26 is still a comfortable shoe for long runs, but I prefer the feel of the Gel-Nimbus 25.
