Brooks Ghost 8 vs. ASICS GEL-Kayano 21 review

ASICS GEL-Kayano 21 provides a secure fitting upper and a plush ride to overpronators. Brooks Ghost 8 delivers a soft and smooth ride with a touch of stability to neutral runners.

NEW! Brooks Ghost 9 vs. ASICS GEL-Kayano 23

The Brooks Ghost 8 and the ASICS GEL-Kayano 21 fall in two different categories of running shoes, but because the ASICS GEL-Kayano 21 can also be worn by neutral runners, it can serve the same crowd as the Brooks Ghost 8.

ADVERTISEMENTS

The uppers of the Brooks Ghost 8 The preceding link takes you to Amazon.com and the ASICS GEL-Kayano 21 are very different in that the ASICS GEL-Kayano 21 has sturdy stitched-on overlays wrapping the midfoot and a sturdy heel counter at the back of the shoe.

The Brooks Ghost 8 only has no-sew overlays wrapping the midfoot, and overall, the ASICS GEL-Kayano 21 has many more overlays than the Brooks Ghost 8.

The ASICS GEL-Kayano 21 also comes with no-sew overlays in between the stitched-on overlays to provide a more custom fit.

However, some runners may appreciate the looser fit of the Brooks Ghost 8, especially in the forefoot, where it is mostly mesh that provides structure and a bit of a hold.

All in all, the ASICS GEL-Kayano 21 has a much more supportive upper than the Brooks Ghost 8, but the Brooks Ghost 8 provides enough support to keep your foot in place.

While the Brooks Ghost 8 is not meant to provide a super plush running experience like the ASICS GEL-Kayano 21, it provides enough cushioning through its midsole for runners to get a soft ride.

The ASICS GEL-Kayano 21 comes with two layers of foam and GEL cushioning in the heel and the forefoot as well as a sockliner to provide runners with a super plush ride.

This is evident from running shoe lab tests that show that the ASICS GEL-Kayano 21 provides cushioning that is almost to the max in both the heel and the forefoot and for both men and women.

Such cushioning is difficult for the Brooks Ghost 8 to contend with. However, the Brooks Ghost 8 displays a cushioning profile with way above average heel cushioning and a forefoot that is cushy but not too cushy.

In addition, the amount of heel cushionng in the Brooks Ghost 8 for women comes very close to the amount in the ASICS GEL-Kayano 21 for women.

The difference in heel cushioning is a bit larger for men but not too large. The biggest difference can be found in the amount of forefoot cushioning, where the ASICS GEL-Kayano 21 has a very cushy forefoot for both men and women.

Because the Brooks Ghost 8 is a neutral cushioning running shoe, it does not really have to provide stability and support to runners, because they do not need it.

However, it still comes with a couple of features that make it quite stable and even more stable than the ASICS GEL-Kayano 21, according to running shoe lab tests.

The ASICS GEL-Kayano 21 is supposed to provide stability and support, because it is geared toward moderate overpronators.

So it comes with a support system on the medial side of the midsole and a midfoot shank to control overpronation.

However, because it does not provide a huge amount of correction, ASICS also lists it as a running shoe that can be worn by neutral runners.

The Brooks Ghost 8 does not come with a support system on the medial side of its midsole nor a midfoot shank, so it does not provide any kind of pronation control.

However, because it provides a large amount of ground contact – more than the ASICS GEL-Kayano 21 – and has a crash pad on the lateral side that runs from the back of the shoe to the front, it can be seen as a very stable running shoe despite not being a stability running shoe like the ASICS GEL-Kayano 21.

The outsole of the Brooks Ghost 8 is also well separated and displays more separation than the outsole of the ASICS GEL-Kayano 21.

This allows the Brooks Ghost 8 to increase the smoothness of your ride. However, it does not help much with the flexibility of the running shoe, because running shoe lab tests rate it as quite stiff for both men and women.

The ASICS GEL-Kayano 21, on the other hand, is a little bit more flexible than the Brooks Ghost 8 for both men and women.

The Brooks Ghost 8 for women weighs approximately 8.5 oz (241 grams), while the ASICS GEL-Kayano 21 for women weighs approximately 9.5 oz (269 grams).

The men's version of the Brooks Ghost 8 weighs about 10.9 oz (309 grams), and the ASICS GEL-Kayano 21 for men weighs 11.3 oz (320 grams).

If you are a moderate overpronator who is looking for a very soft ride from a running shoe that provides above average stability and support, then the ASICS GEL-Kayano 21 would be worth looking into.

If you are a neutral runner who is looking for a running shoe that provides a good amount of cushioning, a smooth ride, and a good amount of stability, then the Brooks Ghost 8 might be for you.

Also note that the Brooks Ghost 8 is much lighter than the ASICS GEL-Kayano 21 for both men and women, so if you are looking for a lighter running experience, the Brooks Ghost 8 might do a better job than the ASICS GEL-Kayano 21.

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.
