Who should buy the Brooks Glycerin GTS 20

Don't write off the 20th edition of the Brooks Glycerin GTS if you're looking to buy a: 

  • stability running shoe for mild to moderate overpronation
  • softer version of the Brooks Glycerin GTS 19 that's great for road running
  • long-distance running shoe that's stable and protective

Who should NOT buy it

If you want a snug-fitting alternative for your medium to narrow-width foot, the Brooks Adrenaline GTS 21 is the better Brooks option. And if you want comfort straight out of the box, the Brooks Launch GTS 9 can do the job.

Runners who are tight on a budget can look into the Asics GT 1000 10 instead. 

Brooks Glycerin GTS 20 vs. 19

It's not a wildly different shoe from its predecessor. The Brooks Glycerin GTS 20 sees the following changes: 

  • A combination of DNA Loft and BioMoGo DNA foam creates a more responsive and plusher landing
  • A stretchier and wider upper for a more welcoming fit. 
  • It has a less rockered design and a wider base, ramping up stability.

Stability that's not overbearing

The Glycerin GTS 20, apart from its wide base, also uses GuideRails to keep the knee's movements within a safe range of motion. On top of this, the less pronounced rocker geometry of the shoe gives it a feeling of "inherent stability" as testers have confirmed, much like the Asics Gel Kayano

True to how it's dubbed—the "self-driving car of the running shoe world"—the Glycerin GTS 20 "steers" your running as it guides your movements. As one tester puts it, if you've tried the Brooks Launch GTS 9, the support feels as unobtrusive

Easy days made easier

As mentioned, the Brooks Glycerin GTS 20 is strictly for easy days on the road. It doesn't just stabilize the runner's movements; it also creates soft and energetic landings, thanks to its revamped midsole, which most, if not all, consider the "hype piece" of this shoe.

Transitions are also easy in the Glycerin GTS 20, despite its toned-down rocker design. As an experienced running expert has said, the ride "would not be a chore" in this shoe. FYI, a break-in period is necessary for this running shoe. But once broken, the overall ride feels safe, comfortable, and fun. 

The Glycerin GTS 20 comes to life

It's not crazy responsive. To be more precise, the rebound feels soft yet noticeable. According to a reviewer, the Brooks Glycerin GTS 20 feels "dead on the first landing" but "comes alive" when you put all your weight on it and once you break it in.

No harshness from the pavement

The Brooks Glycerin GTS' level of protection is outstanding for easy days. It has a copious amount of foam; one runner says his "heart soars" for a well-cushioned shoe like this one. This helps mute out the shock during each foot strike, preventing strain and fatigue. 

The fit is a miss

This is where things have started to "go south" for several road runners. The Brooks Glycerin GTS 20's upper feels sloppy, especially for medium to narrow feet; it "cries for some more substantial overlays." Some even had to really cinch down the laces down to the last eyelet to feel secure.

Meanwhile, this is a different story for wide-footed runners. the stretchier and more accommodating upper allows for both easy slip-on and comfortable foot wrap.

Ultimately, the Glycerin GTS redeems itself in the heel area. The heel cup provides a "gentle hug." None of the critics have experienced slips in the Brooks Glycerin GTS 20. 

Not for the budget-conscious runners

For a daily trainer, which usually costs $119 per pair, the Brooks Glycerin GTS 20 is way too expensive at $160 a pair. Even for a stability running shoe, which sells for $135 on average, the Glycerin GTS still sits way above. 

Looks like a Brooks, but a good-looking one

It may be the "most Brooks-looking shoe of all time," but the twentieth edition of the Brooks Glycerin GTS is quite the looker. This is because of the hollowed-out logo look shoe, making it more daring.

One says its colorways may "resemble the Florida Gators," but with its revamped upper design, it looks "pretty clean."
