Top Reasons to Buy the Men's ASICS GEL-Nimbus 21

Back and better than ever! ASICS originally released the Nimbus back in 1999 and recently celebrated the shoe's 20th birthday. It returns again to introduce a number of new updates that prove why this ever-popular shoe has withstood the test of time.

Looking for plenty of shock absorption? These guys are loaded to the max! Three different cushioning systems work to deliver incredibly soft landings every time your foot pounds the pavement. If you want to take it easy on your body–while still going hard on your runs–these shoes will give your bones and joints some much needed relief.

There's tons of technology packed into these shoes. We love the Guidance Line and Guidance Trusstic tech that enhance your running performance, improve gait efficiency, and promote midfoot integrity. If you want to take your running form to the next level, these shoes can help get you there.

What People Are Saying About the Men's ASICS GEL-Nimbus 21

If you loved the older models, you're in luck–we're told that the men's GEL-Nimbus 21 is now lighter and more responsive than before thanks to the new FlyteFoam Lyte and FlyteFoam Propel cushioning. Big fan of the ASICS GEL technology? Fear not, you still receive a full-length dose of that cushioning, too!

The name says it all! One shopper noted that the maximal cushioning in these shoes really feels like you're running on a cloud, true to its moniker.

Male runners with wider feet are happy to report that ASICS got the toe box right. The GEL-Nimbus 21 comes available in three different width sizes, allowing you to dial in the perfect fit.

Men's ASICS GEL-Nimbus 21 Updates

In the updated GEL-Nimbus 21, you score a new jacquard mesh that serves up plenty of flex with an optimized FluidFit upper. The real shining feature in this new release is the first-ever ASICS dual-density foam midsole; it keeps your run responsive while still absorbing a massive amount of shock.

Size and Fit of the Men's ASICS GEL-Nimbus 21

General Size and Fit

With three width sizes, you're guaranteed to find the fit that feels amazing for the specifications of your feet. This is a neutral running shoe though, meaning it'll perform best for male runners with medium to high arches who don't need extra support or motion control.


ASICS tweaked the upper of the men's GEL-Nimbus 21 so that the toe box is a little roomier, but you don't lose any critical support in the midfoot area. Despite the added space upfront, your feet will stay snugly saddled in–because no one has time for annoying heel slippage, right?


Near the top of the midsole is the layer of FlyteFoam propel material, designed to return the energy you input to make your stride springier. Beneath that is the FlyteFoam Lyte layer, which serves up long-lasting cushioning for ultra-soft landings that won't break down after high-mileage runs. Finally, both forefoot, midfoot, and rearfoot strikers get to enjoy the GEL cushioning that runs from heel to toe.


The outsole of the men's ASICS GEL-Nimbus 21 has been redesigned for lateral full ground contact. Translation? Smoother transitions throughout your entire gait cycle for better running efficiency.
