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

The Brooks Adrenaline GTS 15 and the ASICS GEL-Kayano 21 fall in the same category of stability running shoes, although the Brooks Adrenaline GTS 15 is considered close to the motion control side of the stability category, so is expected to provide more support than the ASICS GEL-Kayano 21.

ADVERTISEMENTS

The upper of the ASICS GEL-Kayano 21 consists of a combination of stitched-on and no-sew overlays, just like the upper of the Brooks Adrenaline GTS 15.

However, the overlays that wrap the midfoot to keep you on the platform, are all stitched-on overlays on the ASICS GEL-Kayano 21 and no-sew on the Brooks Adrenaline GTS 15, so the ASICS GEL-Kayano 21 is expected to provide a much more secure fit.

The ASICS GEL-Kayano 21 also has a firm heel counter (Heel Clutching System) at the back of the shoe, so should also provide you with a better lock down of the heel on the platform.

And lastly, there is FluidFit running between the main overlays on the ASICS GEL-Kayano 21 to give you a more custom and glove-like fit.

While the no-sew overlays on the Brooks Adrenaline GTS 15 should minimize irritation, they may provide a somewhat looser fit than the ASICS GEL-Kayano 21.

The midsole technologies differ considerably in the two running shoes. The ASICS GEL-Kayano 21 has a FluidRide midsole that has cushioning and bounce back properties. And beneath that there is GEL cushioning in the heel as well as in the forefoot, making the ASICS GEL-Kayano 21 deliver an exceptionally soft ride.

The midsole of the Brooks Adrenaline GTS 15 is constructed slightly different, since the Adrenaline is geared towards giving you lots of support. The Brooks Adrenaline GTS 15 has a BioMoGo DNA midsole with an anatomical DNA layout for cushioning.

In addition, there is a full-length crash pad under the shoe to absorb shock and provide a smooth heel-to-toe transition.

But most importantly, the Brooks Adrenaline GTS 15 has a medial post (Progressive Diagonal Rollbar) to control overpronation. While the ASICS GEL-Kayano 21 delivers support and stability through the Dynamic DuoMax Support System in its midsole, the Brooks Adrenaline GTS 15 can be seen to control overpronation more strongly than the ASICS GEL-Kayano 21.

And the final stability feature on the Brooks Adrenaline GTS 15 is that it provides almost full ground contact whereas the ASICS GEL-Kayano 21 has a midfoot shank that prevents total ground contact between the forefoot and the rearfoot.

The configuration of the rubber lugs are very different in the outsoles of the two running shoes. The Brooks Adrenaline GTS 15 has small squarish rubber lugs with many flex grooves, while the ASICS GEL-Kayano 21 has groups of large rubber compartments in between a couple of main flex grooves.

This should make the Brooks Adrenaline GTS 15 feel a little bit more flexible under your foot than the ASICS GEL-Kayano 21.

The women's version of the Brooks Adrenaline GTS 15 weighs approximately 9.3 oz (264 grams), while the ASICS GEL-Kayano 21 for women weighs approximately 9.5 oz (269 grams). The men's version of the Brooks Adrenaline GTS 15 weighs about 11.3 oz (320 grams), and the ASICS GEL-Kayano 21 for men weighs 11.3 oz (320 grams).

If you are looking for a running shoe that can give you a moderate amount of stability and support with a lot of cushioning, a very plush feel, and a secure fit, then the ASICS GEL-Kayano 21 might be it.

And if you require lots of support and stability from a running shoe that can give you a smooth, comfortable, and stable ride, then the Brooks Adrenaline GTS 15 would be one to look into.
