NEW! ASICS GEL-Kayano 23 vs. Brooks Adrenaline GTS 17 and ASICS GEL-Kayano 22 vs. Brooks Adrenaline GTS 16 and ASICS GEL-Kayano 23 vs. Brooks Adrenaline GTS 16 and ASICS GEL-Kayano 24 vs. Brooks Adrenaline GTS 17

The ASICS GEL-Kayano 22 and the Brooks Adrenaline GTS 15 fall in the same category of stability running shoes, but the ASICS GEL-Kayano has come to be known for its plushness and the Brooks Adrenaline GTS for its stability and support.

ADVERTISEMENTS

The ASICS GEL-Kayano 22 The preceding link takes you to Amazon.com does not have many stitched-on overlays in its upper; it consists mainly of no-sew overlays with mesh that can stretch in different directions.

Because of the lack of stitched-on overlays and overlays in general, the ASICS GEL-Kayano 22 does not have many places where it can irritate your foot, and the fit may feel looser than in the Brooks Adrenaline GTS 15.

The Brooks Adrenaline GTS 15 also has an upper that consists mainly of no-sew overlays, but it still has stitched-on pieces at the front of the shoe and another one wrapping the heel.

In addition, it has a broad overlay on the medial side of its upper that provides overpronators with the kind of support they need.

The bunion window of the ASICS GEL-Kayano 22 is more open and free than that of the Brooks Adrenaline GTS 15, so if you have large bunions, the ASICS GEL-Kayano 22 may provide more comfort in that area.

Finally, the ASICS GEL-Kayano 22 has an external heel counter that locks the heel down on the platform.

While the Brooks Adrenaline GTS 15 does not have such a heel counter, it provides sturdy stitched-on overlays at the back that should have an effect that comes close to that provided by the ASICS GEL-Kayano 22.

All in all, the Brooks Adrenaline GTS 15 has an overall more supportive upper than the ASICS GEL-Kayano 22.

The ASICS GEL-Kayano is known for the cushioning that it provides, which is delivered through two layers of foam with GEL cushioning in between. This is no different in the ASICS GEL-Kayano 22.

The Brooks Adrenaline GTS 15 on the other hand, is known for its cushioning that is not too soft nor too firm; it's just right and lies somewhere in the middle.

This is confirmed by running shoe lab tests, which show that the Brooks Adrenaline GTS 15 has a similar cushioning profile as the ASICS GEL-Kayano 22, but provides almost twice as less cushioning than the ASICS GEL-Kayano 22.

So if cushioning is what you are after, the ASICS GEL-Kayano 22 would be the one to consider above the Brooks Adrenaline GTS 15, which is a good running shoe for overpronators who prefer a somewhat firmer platform to run on that is also better for heavier runners.

Another difference in the midsole is the fact that the Brooks Adrenaline GTS 15 has a crash pad that runs along the entire length of the midsole.

The ASICS GEL-Kayano 22 does not have a crash pad per se, but instead provides GEL cushioning in the heel and good separation in the outsole under the heel to soften your landings, and does a good job of it according running shoe lab tests, so is a good running shoe for heel-strikers.

However, the full-length crash pad on the Brooks Adrenaline GTS 15 should allow you to get a smoother ride from heel-strike to toe-off.

This also adds to the stability of the running shoe, which is reinforced by a long piece of firmer foam on the medial side of the shoe that starts at the back of the shoe and consists of several densities of foam for more gradual pronation control.

While the ASICS GEL-Kayano 22 also provides reinforcement on the medial side of the midsole, it is more subtle than the support provided by the Brooks Adrenaline GTS 15; it does not run as high or as far back.

Therefore, the ASICS GEL-Kayano 22 cannot beat the Brooks Adrenaline GTS 15 in the support department.

The rubber outsoles also differ in the two running shoes. While both has the same amount of horizontal flex grooves in the forefoot, the ASICS GEL-Kayano 22 has larger slabs of rubber, while the Brooks Adrenaline GTS 15 has smaller rubber pods with more separation between them.

The latter benefits shock absorption and dissipation, and again increases the potential for a smoother ride.

However, while one would expect the amount of flexibility to also go up with the amount of separation, running shoe lab tests have shown that both the ASICS GEL-Kayano 22 and the Brooks Adrenaline GTS 15 are almost equally flexible for both men and women.

The women's version of the Brooks Adrenaline GTS 15 weighs approximately 9.3 oz (264 grams) and the ASICS GEL-Kayano 22 for women weighs 9.6 oz (272 grams).

The men's versions of the shoes weigh 11.3 oz (320 grams) and 11.6 oz (329 grams), respectively, with the Brooks Adrenaline GTS 15 being the lighter one.

If you are a runner who tends towards being a severe overpronator, but who does not need a motion control running shoe, the Brooks Adrenaline GTS 15 would be the option to look into.

If on the other hand, you are a moderate overpronator who is looking for a very soft ride, then the ASICS GEL-Kayano 22 may be able to give you what you want.

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.
