ASICS Gel Nimbus 20: overall impression

The ASICS Gel Nimbus 20 is another excellent shoe that works well for neutral runners.

The shoe features new updates for a more satisfying running experience. It offers exceptional cushioning and unmatched comfort no matter how far you run.

Updates of the ASICS Gel Nimbus 20

ASICS has made minor enhancements in the midsole and outsole of the Nimbus 20. The major update of the shoe can be seen in its upper.

The shoe now features a new gradient mesh that delivers lightweight breathability. The mesh allows the foot to move naturally and it also provides a more customized fit.

The Nimbus 20 is breathable

The upper of the ASICS Gel Nimbus 20 features the new gradient mesh material that provides the foot a breathable coverage. The mesh is smooth and flexible. It gives the foot a more glove-like fit.

Incorporated into the mesh material are the seamless 3D printed overlays. It delivers added structural integrity at the same time reduces irritation and blisters.

Secure heel fit

For a reliable midfoot security, ASICS introduced a new lacing system. Along with it are the padded tongue and collar that also provides added comfort and foot security.

The shoe also features the Heel Clutching System that makes for a more secure heel fit.

Responsive ride in the Gel Nimbus 20

The Nimbus 20 utilizes the same midsole technology found in the ASICS Gel Nimbus 19. However, ASICS made minor enhancements in the midsole to make the ride quality smoother and more responsive.

In the midsole is the FlyteFoam technology which is commonly found in some ASICS running shoes. This technology provides lightweight cushioning. It is efficient in absorbing shock during impact and gives high energy return for a more powerful toe-off.

Along with the FlyteFoam is the FluidRide technology. It provides added underfoot cushioning without adding too much weight.

The notable Rearfoot and Forefoot Gel Cushioning is also found in the midsole of the shoe. The gel cushioning system allows runners to experience a more responsive ride. It also delivers added cushioning to the foot for impact protection.

Reliable traction

In the outsole of the Nimbus 20 is the ASICS High Abrasion Rubber (AHAR) material.

It is a reliable material specifically placed in high-wear areas for maximum durability. Along with the AHAR is the DuraSponge material. It is placed in the forefoot area for flexibility and added cushioning.

The outsole has a less aggressive configuration, but it still provides reliable traction on the road and other paved surfaces.

Adaptive fit

The ASICS Gel Nimbus 20 is available in standard sizes, and it fits well for runners with medium and slightly wide foot measurements. The shoe has a medium measurement from the heel to the forefoot, and the toe box area is wide.

The gradient mesh material in the upper of the shoe is flexible. It adapts to the natural shape of the foot which results to a more adaptive fit.

The new lacing system of the shoe also contributed to the overall fit of the shoe. The lacing system is very efficient in providing the foot a more secure midfoot lock-down.

Impressive comfort

Compared to its predecessor, the Nimbus 20 is more breathable and comfortable.

The gradient mesh upper did a good job in providing the foot a breathable coverage. The tongue and collar have also contributed to the overall comfort of the shoe.

The comfort and breathability of the ASICS Gel Nimbus 20 is comparable to that of the Brooks Ghost 10.

Impressive performance

I own several lightweight running shoes, and they perform well on up-tempo training and long-distance runs. The ASICS Gel Nimbus 20 has an average weight (264 grams for women’s and 306 grams for men’s), and it is as good as the other running shoes that I have.

The overall ride quality of the shoe is impressive. The cushioning provides a responsive and flexible ride. The forefoot is flexible, and the 13mm heel drop is just right for my personal preference.

The Nimbus 20 also has a good level of traction on paved surfaces. It even performed well on slightly wet and slippery surfaces.

Very durable

The ASICS Gel Nimbus 20 is a bit expensive compared to the other daily running shoes that I have. I’m not complaining about the price of the shoe because it is also made from high-quality materials and is very durable.

The outsole is made from high-abrasion rubber that remains unbroken after several miles. The upper also shows no significant damage.

The only minor thing that I noticed is the new lacing system. I think it was poorly made. The foam is too thin and not properly stitched to the upper material. It started ripping off after using the shoe a few times.

The shoe is more breathable than its predecessor, and it provides a more comfortable in-shoe feel all throughout the run. It is a bit expensive, but considering the performance and shoe durability, I think the Nimbus 20 is a good investment.
