Great fit
Have been having foot issues lately.
Bought these because of a friend recommendation.
Very satisfied with the comfort. They have a lot of padding (gel and generous room in the toe box.
Liked them so much, I bought a second pair (different color)!

Great fit, feels great!
It was time to upgrade my GT2000-2’s, so I walked into a local Asics store to see what’s currently available.
After talking about distance and pronation (which i never properly tested, the very knowledgeable employee put me on a treadmill wearing special shoes and some sensors and we found out that neutral shoes are fine for me as well based on my running metrics.
Trying on the Nimbus and Cumulus (running around the store for a few minutes), i decided to go for the Nimbus, as they gave me a bit more support in the rear when doing faster turns.
Went out for a 5k run after i got home and they felt great to me. Glad i upgraded!

Only a week old. I put them side by side with my 20's and I don't really agree with some other comments suggesting that the 21's have a bigger toe box. The sole/platform is somewhat wider, but actual foot space is indeed smaller than the 20's. They aren't the most visually appealing Asics ever, but I got black and white so they can pass. I ended up a half size larger than my 20's and they will do for now. Not awful, and not great. I've probably a tough reviewer, in that I haven't been fully satisfied with my Asics shoes in recent years. The 21 continues that trend.

Great shoe but they run a size small
I always wear the Nimbus model and wear a size 12 but this model I couldn't even get it on my foot. Other than that issue the shoe is perfect.

Greatly improved fit and ride
I have been running on Nimbus for five years now and the changes that have been made in this version are all positive. Toe box change transforms the feel of the shoe and the new foam does as advertised. I run about 20 miles per week and Nimbus has always worn welll.

Ugliest Nimbus Yet
My expectations for the Nimbus 21 were pretty high. While I thoroughly enjoyed the 19 and 20s, the 21s absolutely look horrendous! They are absolutely ugly and look completely outdated and clunky. They are somewhat comfortable, but I will be stockpiling my 20s or switch to New Balance until they come out with a decent looking Nimbus.
