Brooks Glycerin 13 vs. ASICS GEL-Kayano 21 review

Brooks Glycerin 13 provides a comfortable, soft, and smooth ride to neutral runners. ASICS GEL-Kayano 21 provides a secure fitting upper and a plush ride to moderate overpronators.

NEW! Brooks Glycerin 13 vs. ASICS GEL-Kayano 22 and Brooks Glycerin 14 vs. ASICS GEL-Kayano 23

The Brooks Glycerin 13 and the ASICS GEL-Kayano 21 fall in two entirely different categories of running shoes with the Brooks Glycerin 13 intended to be worn by neutral runners and the ASICS GEL-Kayano 21 by mild to moderate overpronators.

ADVERTISEMENTS

The uppers of the Brooks Glycerin 13 The preceding link takes you to Amazon.com and the ASICS GEL-Kayano 21 have a couple of similarities about them.

First off, the ASICS GEL-Kayano 21 has stitched-on overlays wrapping the midfoot to give you a good amount of support there.

While the Brooks Glycerin 13 does not have as many stitches in its overlays, there are a few in the broad overlays that wrap the midfoot.

So both running shoes should provide you with a good lock down around the midfoot.

Another similarity is that both running shoes have no-sew overlays running in their uppers. However, the overlays on the Brooks Glycerin 13 are more plentiful than those on the ASICS GEL-Kayano 21. These overlays are meant to provide you with a more custom and close-to-foot fit.

A difference between the uppers is that the ASICS GEL-Kayano 21 has an external heel counter while the Brooks Glycerin 13 does not. Nonetheless, you should still be able to get an appropriate amount of support behind the heel from the Brooks Glycerin 13.

The midsoles of the ASICS GEL-Kayano 21 and the Brooks Glycerin 13 both provide heel-to-toe cushioning, but in different degrees.

What the ASICS GEL-Kayano 21 implements that the Brooks Glycerin 13 does not is extra cushioning in the form of GEL cushioning in the heel and in the forefoot.

This GEL cushioning lies in between two layers of foam. The one closest to the foot is the softest layer and the one closest to the ground the more responsive one.

All this helps the ASICS GEL-Kayano 21 deliver a super soft ride to runners, while it is not a neutral cushioning running shoe.

However, because it is geared towards mild to moderate overpronators, it can also be worn by neutral runners.

The Brooks Glycerin 13 is a neutral cushioning running shoe, so meant to provide cushioning to runners who do not need stability and support.

However, running shoe lab tests have shown that the ASICS GEL-Kayano 21 is still more cushy than the Brooks Glycerin 13 in both the heel and the forefoot and for both men and women.

The main difference in the midsoles can be found on the medial side of the shoe where the ASICS GEL-Kayano 21 has a support system in place to control overpronation, while the Brooks Glycerin 13 does not.

The rubber outsoles of the Brooks Glycerin 13 and the ASICS GEL-Kayano 21 are quite different in construction. The two biggest differences can be found under the midfoot and the heel.

The heel of the Brooks Glycerin 13 is more narrow and rounded than that of the ASICS GEL-Kayano 21. Its purpose is to take stress off joints and provide you with a better alignment.

At the midfoot, the ASICS GEL-Kayano 21 has a midfoot shank to provide structural integrity and support, while the Brooks Glycerin 13 provides full ground contact under the midfoot.

The full ground contact of the Brooks Glycerin 13 under the entire shoe benefits smoother transitions from heel-strike to toe-off.

In terms of separation, the ASICS GEL-Kayano 21 is a bit more separated than the Brooks Glycerin 13, but both running shoes have a good amount of flex grooves running from side to side in the forefoot, which is good for flexibility.

Flexibility varies between the two running shoes with the ASICS GEL-Kayano 21 being a little bit more flexible than the Brooks Glycerin 13 for women according to running shoe lab tests.

For men, the Brooks Glycerin 13 turns out to be twice as flexible as the ASICS GEL-Kayano 21.

The women's version of the Brooks Glycerin 13 weighs approximately 8.9 oz (252 grams), while the ASICS GEL-Kayano 21 for women weighs 9.5 oz (269 grams).

The men's version of the Brooks Glycerin 13 weighs about 11.0 oz (312 grams), while the ASICS GEL-Kayano 21 for men weighs 11.3 oz (320 grams).

Making a choice between the ASICS GEL-Kayano 21 and the Brooks Glycerin 13 is not that difficult if you are an overpronator, since the ASICS GEL-Kayano 21 would be the one that was made for you.

However, if you are a neutral runner, you could go either way. If lots of cushioning is what you are after, then the ASICS GEL-Kayano 21 would be the one to look into. Otherwise the Brooks Glycerin 13 would be good for a relatively cushy and smooth ride.
