ASICS GEL-Kayano 23 vs. Brooks Ghost 9 review

ASICS GEL-Kayano 23 provides softness, comfort, and a touch of stability to overpronators. Brooks Ghost 9 provides a soft ride with a touch of stability to neutral runners.

The ASICS GEL-Kayano 23 and the Brooks Ghost 9 fall in two different categories of running shoes, with the ASICS GEL-Kayano 23 being a stability running shoe and the Brooks Ghost 9 a neutral cushioning running shoe, although the ASICS GEL-Kayano 23 can also be worn by neutral runners (according to ASICS).

ADVERTISEMENTS

The uppers of the ASICS GEL-Kayano 23 The preceding link takes you to Amazon.com and the Brooks Ghost 9 have been kept very light with light no-sew overlays and mesh that has a structure that reduces the need for overlays.

Therefore, you can expect to get a comfortable and somewhat loose fit from both running shoes.

The big difference between the uppers can be found at the back, where the ASICS GEL-Kayano 23 comes with a sturdy external heel counter, but the Brooks Ghost 9 The preceding link takes you to Amazon.com only provides overlays for extra support.

Therefore, you can expect the ASICS GEL-Kayano 23 to provide a bit more support than the Brooks Ghost 9 at the back.

The toe box has been kept open and free on both running shoes, but if you have large bunions, they might get more room in the ASICS GEL-Kayano 23 than in the Brooks Ghost 9 due to the positioning of the no-sew overlays near the bunion window.

Both the ASICS GEL-Kayano 23 and the Brooks Ghost 9 are meant to provide runners with a soft ride, but because the Brooks Ghost 9 is the cushioning running shoe among the two, it is expected to provide more cushioning than the ASICS GEL-Kayano 23.

The latter is true to some degree when you analyze running shoe lab test results.

For women, there are almost no differences to be noted between the amount of cushioning provided in the forefoot and the heel of the ASICS GEL-Kayano 23 and the Brooks Ghost 9.

They both provide a large amount of heel cushioning and an above average amount of forefoot cushioning to women.

However, when you look at the men's versions of the running shoes, you will notice some differences, especially in the amount of heel cushioning.

The Brooks Ghost 9 provides a large amount of heel cushioning to men, compared to an above average amount in the ASICS GEL-Kayano 23.

The amount of forefoot cushioning does not differ that much between the two running shoes, but the ASICS GEL-Kayano 23 provides just a tiny bit more than the Brooks Ghost 9.

All in all, you should be able to get a soft and comfortable ride from either the ASICS GEL-Kayano 23 or the Brooks Ghost 9.

The ASICS GEL-Kayano 23 comes with a support system on the medial side of its midsole and a midfoot shank for midfoot integrity, but because ASICS lists the ASICS GEL-Kayano 23 as also suitable to be worn by neutral runners, the amount of stability and support it provides lies just above average. Otherwise, it would get in the way of neutral runners.

Overpronators should expect to get a moderate amount of stability and support from the ASICS GEL-Kayano 23.

The Brooks Ghost 9 is exclusively for neutral runners, but because it provides a good amount of ground contact and comes with a crash pad that runs from the back of the shoe all the way to the front, running shoe lab tests rate it as being more stable than the ASICS GEL-Kayano 23.

In fact, the amount of stability is quite high for a neutral running shoe.

The outsole of the Brooks Ghost 9 is also quite separated with small rubber pods compared to the large slabs of rubber under the ASICS GEL-Kayano 23.

The separation should benefit the smoothness of your ride, but according to running shoe lab tests, it does not help with flexibility in the case of the Brooks Ghost 9.

In that case, the ASICS GEL-Kayano 23 turns out to be much more flexible than the Brooks Ghost 9 for both men and women.

The women's version of the Brooks Ghost 9 weighs approximately 9.0 oz (255 grams), and the ASICS GEL-Kayano 23 for women weighs 9.4 oz (266 grams).

The men's versions of the shoes weigh 10.5 oz (298 grams) and 11.5 oz (326 grams), respectively, with the Brooks Ghost 9 being the lighter one.

The Brooks Ghost 9 is a relatively light running shoe that provides neutral runners with a soft, comfortable, smooth, and very stable ride.

However, if you are an overpronator, the ASICS GEL-Kayano 23 was meant to be for you more than the Brooks Ghost 9, despite the ASICS GEL-Kayano 23 being rated as somewhat less stable than the Brooks Ghost 9.

Neutral runners could go either way, but keep in mind that the Brooks Ghost 9 was built with you in mind more than the ASICS GEL-Kayano 23 was.

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.
