The Brooks Glycerin 16 and the Brooks Adrenaline GTS 18 fall in two different categories of running shoes with the Brooks Glycerin 16 being a cushioned running shoe for neutral runners and the Brooks Adrenaline GTS 18 being a stability running shoe for overpronators.

ADVERTISEMENTS

Despite falling in two different running shoe categories, the uppers of the Brooks Glycerin 16 and the Brooks Adrenaline GTS 18 display quite a few similarities.

Both the Brooks Glycerin 16 The preceding link takes you to Amazon.com and the Brooks Adrenaline GTS 18 have an upper that is quite open from midfoot to forefoot by having no overlays in that area and relying mostly on mesh to provide lightweight support.

Therefore, both the Brooks Adrenaline GTS 18 The preceding link takes you to Amazon.com and the Brooks Glycerin 16 offer a good amount of comfort in the toe box.

They come with some extra support around the midfoot towards the back of the running shoes by having no-sew overlays in that area.

The overlays are pretty broad and connect the saddle well to the midfoot on the Brooks Glycerin 16.

The overlays are more pulled back on the Brooks Adrenaline GTS 18 and deliver somewhat less support directly across the midfoot.

Both the Brooks Adrenaline GTS 18 and the Brooks Glycerin 16 are pretty seamless and only come with some stitches in the saddle, but these should not cause any irritation.

The backs of the two running shoes expose quite a bit of mesh, but the Brooks Adrenaline GTS 18 is the one that throws on some extra overlays for additional support at the back.

Finally, because the Brooks Glycerin 16 comes with an internal bootie that surrounds your foot, it is likely to deliver a closer-to-foot fit than the Brooks Adrenaline GTS 18.

The Brooks Adrenaline GTS 18 and the Brooks Glycerin 16 are clearly geared towards delivering comfort to runners and only providing enough support to keep your foot on the running platform.

Neither can be said to go overboard with support in their upper, but the Brooks Glycerin 16 provides a better wrap around the midfoot, while the Brooks Adrenaline GTS 18 delivers more support around the heel.

The Brooks Glycerin 16 and the Brooks Adrenaline GTS 18 also display similarities in their midsoles by having one main layer of foam.

This layer of foam provides a good amount of ground contact and is well segmented on the lateral side to deliver smoother heel-to-toe transitions as well as add stability to your runs.

One of the differences between the midsoles is that they consist of two different types of midsole material.

The Brooks Glycerin 16 has a DNA LOFT midsole, while the Brooks Adrenaline GTS 18 has a BioMoGo DNA midsole.

The midsole material used by the Brooks Glycerin 16 is meant to deliver a very soft ride, while that of the Brooks Adrenaline GTS 18 generally delivers a ride that is not too soft nor too firm.

However, both running shoes have been found to deliver an overall soft ride to both men and women, but not surprisingly, the Brooks Glycerin 16 is the one that pushes the amount of overall cushioning to the max.

Midsoles that are very soft are typically also a bit less stable, so despite the full ground contact delivered by the Brooks Glycerin 16, the Brooks Adrenaline GTS 18 would be the one to deliver a bit more stability even if it did not have a medial post, which it does.

The medial post in the Brooks Adrenaline GTS 18 is fairly long and runs high to provide a good degree of pronation control to overpronators.

The Brooks Glycerin 16 does not come with such a medial post, because it is a running shoe that is meant to be worn by neutral runners.

Because the amount of pronation control delivered by the medial post of the Brooks Adrenaline GTS 18 is fairly strong, such support would get in the way of neutral runners, so the Brooks Adrenaline GTS 18 is not really a suitable running shoe for neutral runners.

The outsoles of the Brooks Glycerin 16 and the Brooks Adrenaline GTS 18 are similar in that they display quite a bit of separation and segmentation.

They both come with well-segmented crash sections under the heel to isolate shock from the rest of the outsole, and they both provide a good seamless connection between the heel and the forefoot, although the Brooks Glycerin 16 provides a better connection on the medial side, because it does not have a small midfoot shank like the Brooks Adrenaline GTS 18 does on that side.

The Brooks Glycerin 16 also has more deep flex grooves than the Brooks Adrenaline GTS 18, but because it provides so much cushioning, it is a stiff running shoe for both men and women.

The Brooks Adrenaline GTS 18 is also a stiff running shoe, because it also delivers a good amount of forefoot cushioning and does not have as many deep flex grooves as the Brooks Glycerin 16, but it might still feel a bit more flexible than the Brooks Glycerin 16 due to the more moderate amount of cushioning.

The women's version of the Brooks Adrenaline GTS 18 weighs approximately 8.3 oz (235 grams), and the Brooks Glycerin 16 for women weighs 9.4 oz (266 grams).

The men's version of the Brooks Adrenaline GTS 18 weighs 9.7 oz (275 grams), and the Brooks Glycerin 16 for men weighs about 10.6 oz (301 grams).

Making a decision between the Brooks Adrenaline GTS 18 and the Brooks Glycerin 16 should not be difficult, because they are meant to be worn by two different types of runners.

Both running shoes can deliver an overall soft and smooth ride, but your ride will just be much softer in the Brooks Glycerin 16, while it will be more stable in the Brooks Adrenaline GTS 18.

If you are a moderate to severe overpronator, you may want to look into the Brooks Adrenaline GTS 18, and if you are a neutral runner, the Brooks Glycerin 16 was built with your needs in mind.
