Customer Reviews ASICS GEL-Nimbus® 21

Asics are my go-to for my workouts. Any HIIT, aerobics training! Comfy and somewhat lightweight.

I'm happy the 21's fit like the 18's, for the most part. Those were still the best. The 21 has the room in the toe box like it should. They do run a 1/2 size small though so buy a bigger size. They are cushiony but not as much as the 18's but definitely better than the 19's and 20's. I hope they come out with better color choices! Where are the PINK ones?? Girls like pink! I bought 2 of the 21's so far. I'm waiting for more color choices that I like. I was told they will come out with a couple more. I had bought about 6 or 7 of the 18's when they were out because they were the best and loved the color choices. So ASICS,......step it up w/the colors!

I am an avid fan of Asics Nimbus. I own the 17, 18 and 19 amongst several pairs of Kayanos. I have always worn a 9 in the nimbus until now. I had to send them back and order a 1/2 size larger. My toe touched the end. I can't wait to get the new ones. The arch support and cushioning felt great. The toe is more rounded which looks great. Not pointy like the 20's. Just order at least a half size larger.

After running outside in these shoes for over a week, they just do not have the "sweet" cushion and support when you first break in a pair of running shoes. I have been a loyal Asics customer for over 25 years and I am a little disappointed in the support and cushioning of these particular shoes. However, I love the color. I am going back to Gel Kayano 24.

The shoes were stiffer than my previous Nimbus.I really don't have anything else to say.

Narrower than expected for D wide sneaker. Too bad that I had to return due to that issue as the Cumulus and GT-2000 styles in the same wide option fit great. Hopefully they remove that plastic piece along my big toe joint and make it all fabric around the toebox like the Cumulus.

I love them when I can find my size - but they shipped me 2 left shoes

This is my 3rd pair with same size and width . For some reason I am just having the worst time breaking them in. They just feel different, almost more narrow. I find myself constantly adjusting the laces on a run.

I usually love these shoes but this one hurts my feet!

These shoes have changed and not for the better. I've been a Nimbus subscriber. Whenever I'd try on different running shoes, they just felt so "unfamiliar". Until I'd try on a Nimbus and it felt like home. Well, this version is stiff and not comfortable at all. Sad to say, I don't think I'll be wearing the Nimbus any longer.

While these are mostly used for Zumba and Orangetheory workouts, the running shoe was recommended to me by a fitness instructor who loves them. In my experience, the shoes have been entirely stiff and do not seem to be breaking in well. They're comfortable when first laced up but I can't wait to take them off by the end of class. During the workout I'm very aware of my feet. I'm typically 10.5 but got 11 for these and am glad I did as they run small and narrow. They are good looking shoes and I'll continue to wear them as I can't afford to replace them.

Nice looking sneaker but runs small so unfortunately I had to return it. Maybe 1/2 size larger would have been a better fit.

Don't get me wrong- I love my Nimbus shoes. They just don't hold up for me. The forefoot sole is already smooth and I haven't done crazy miles. The padding on the ankles is also ripped up.

Great stability and color yet shoe sizing a problem. I'm a consistent 10 and yet after returning those and replacing them with 10 1/2 Wide they are still too small!

I bought my normal size (which is accurate 95% of the time) and it was WAY too small. This is a lot of shoe - material and padding- especially in the heel. However, it's still lightweight. Obviously I never test drive these so I don't know how they perform.

I have been wearing Gel Nimbus for over a decade now. This is the first pair that my socks slide down constantly. I'm talking brand spankin new socks. Not sure what's going on. I blame it on the shoe lol. But these shoes are usually amazing for my feet, fun colors, laces stay tied. Love, love, love them - but not these 21s. Womp womp

Ordered a half size Up but a little tight in toe box when walking on pavement . There was an ASICS sneaker that has been discontinued and accommodated custom orthotics and was perfect for me . But this is Gel-nimbus 21 is not .

These are a little more narrow than I was expecting for wide width. Comfort level is okay, but I hoped for more.

These shoes are very cute but they are not true to size or width - too small and too tight.

No arch support. I was looking for a running shoe that was good for plantar fasciitis.

I am disappointed with the cushion of the shoes. I have been wearing Hooka shoes for walking and comfort. I usually wear Asics for working out but hope to find more comfortable shoes for gym wear.

I have been wearing Asics Shoes for such a long time that I don't even remember whether my first models were a Gel Nimbus. They fit very well and are really comfortable. However, I have noticed that the latest models do not look as good as gel nimbus 18 for example, the 21 model looks a bit cheap and does not really reflect the quality that you would expect from a shoe in this price range unfortunately

The Nimbus 21 are narrow at the heel. They feel just like the Cumulus with little arch support. I'm glad I did not pay full price for this pair.

The soles are a bit stiff. I use to love Ascic Nimbus because it felt like I was running on clouds. Since the change to flytefoam, I don't like them as much. Fit is accurate.
