ASICS GEL-Kayano 23 vs. ASICS GEL-Nimbus 19 review

ASICS GEL-Kayano 23 provides softness, comfort, and a touch of stability to overpronators. ASICS GEL-Nimbus 19 delivers a soft but responsive ride to neutral runners...

The ASICS GEL-Kayano 23 and the ASICS GEL-Nimbus 19 fall in two different categories of running shoes with the ASICS GEL-Kayano 23 being a stability running shoe and the ASICS GEL-Nimbus 19 a neutral cushioning running shoe although the ASICS GEL-Kayano 23 is also listed by ASICS as a running shoe that can be worn by neutral runners.

ADVERTISEMENTS

The uppers of the ASICS GEL-Kayano 23 The preceding link takes you to Amazon.com and the ASICS GEL-Nimbus 19 are quite similar in that they have a minimum amount of stitches in them to increase the amount of comfort and reduce irritation.

They also both have the ASICS logo to provide some structure and hold around the midfoot.

The main difference lies in the type of mesh used and the fact that the ASICS GEL-Nimbus 19 The preceding link takes you to Amazon.com comes with 3D printed overlays running throughout the entire upper to increase the amount of support.

The ASICS GEL-Kayano 23 comes with normal extra no-sew overlays on the medial side to provide support around the midfoot.

The mesh on both running shoes tends to stretch as your foot moves, but unlike the mesh on the ASICS GEL-Kayano 23, the mesh on the ASICS GEL-Nimbus 19 is tightened and loosened in zones, so has a greater possibility of providing a tighter fit than the ASICS GEL-Kayano 23.

Both the ASICS GEL-Kayano 23 and the ASICS GEL-Nimbus 19 come with an external heel counter at the back to provide extra support behind the heel and lock it in.

All in all, both the ASICS GEL-Kayano 23 and the ASICS GEL-Nimbus 19 should be able to provide enough support through their uppers, but the ASICS GEL-Kayano 23 might offer a somewhat looser and more comfortable fit than the ASICS GEL-Nimbus 19, especially in the forefoot.

The midsoles of the ASICS GEL-Nimbus 19 and the ASICS GEL-Kayano 23 are quite similar because both come with two layers of foam with GEL cushioning between these two layers.

The type of foam is also the same in the bottom layer. This foam (FlyteFoam) is meant to be responsive and have bounce back properties.

Due to the construction of the bottom layer of foam, the ASICS GEL-Nimbus 19 seems to provide a bit more cushioning under the heel than the ASICS GEL-Kayano 23, and the ASICS GEL-Nimbus 19 has one pod of GEL cushioning in the forefoot more than the ASICS GEL-Kayano 23.

In general, the ASICS GEL-Nimbus is meant to provide more cushioning than the ASICS GEL-Kayano, because the former is a cushioning running shoe and the latter a stability running shoe.

Both running shoes come with an extra 3 mm of height under the heel of the female versions of the running shoes to take tension off the Achilles tendon. This also tends to increase the amount of heel cushioning for women.

Another difference between the midsoles is that the ASICS GEL-Kayano 23 comes with a support system in the form of reinforced foam on the medial side of the running shoe to help stop the feet of overpronators from rolling too far inward.

This support system includes a midfoot shank that connects the lateral side to the medial side and provides structural integrity and support under the midfoot.

The ASICS GEL-Nimbus 19 also comes with a midfoot shank, but its lateral and medial pieces are not connected like under the ASICS GEL-Kayano 23.

The outsoles of the ASICS GEL-Kayano 23 and the ASICS GEL-Nimbus 19 look quite similar in layout. They differ mainly in the length of flex grooves.

The vertical flex groove that runs in the middle of the outsole from back to front stops earlier in the ASICS GEL-Nimbus 19 than it does it in the ASICS GEL-Kayano 23. This flex groove is meant to help with gait efficiency.

Another difference is that the frontmost flex groove under the ASICS GEL-Nimbus 19 does not run from side to side like under the ASICS GEL-Kayano 23.

Horizontal flex grooves in the forefoot benefit the flexibility of a running shoe, so it is not surprising that running shoe lab tests rate the ASICS GEL-Kayano 23 as being quite flexible for both men and women.

Other than that, both running shoes come with a good amount of rubber in their outsoles so should last quite a long time.

The women's version of the ASICS GEL-Kayano 23 weighs approximately 9.4 oz (266 grams), while the ASICS GEL-Nimbus 19 for women weighs approximately 8.9 oz (252 grams).

The men's version of the ASICS GEL-Kayano 23 weighs about 11.5 oz (326 grams), and the ASICS GEL-Nimbus 19 for men weighs 11.1 oz (315 grams).

If you are a neutral runner or an underpronator (someone whose feet tend to roll outwards) who is looking for a soft ride, you may want to look into the ASICS GEL-Nimbus 19.

And if you are a neutral runner or a moderate overpronator (someone whose feet tend to roll inwards) who is looking for a soft ride, the ASICS GEL-Kayano 23 would be the one to look into.

Note: The weight of a running shoe depends on the size of the running shoe, so any weights mentioned in this review may differ from the weight of the running shoe you choose to wear. Running shoes of the same size were compared for this review.
