Enter a world of soft. lightweight cushion and support with the new Brooks Glycerin GTS 21.

A new blend of DNA LOFT v3 foam makes this running shoe noticeably softer than the Brooks Glycerin GTS 20 so that your foot disappears into the shoe. Combined with an updated outsole geometry. DNA LOFT v3 gives the Glycerin GTS 21 smooth and effortless heel-to-toe transitions for a distraction-free run.

GuideRails unobtrusively keep the foot on a natural motion path while reducing excess joint movement. A new engineered warp knit upper flexibly hugs the foot for a plush fit with plenty of support where you need it.

WHY PACERS CARRIES THESE SHOES:

When you’re running. you don’t want to think about whether you have enough cushion or whether your foot has the proper support. You want to focus on the things that are important—like where the nearest bathroom is or how much longer until you can get back to reclining on the couch.

The Brooks Glycerin GTS 21 frees up your mind so you can think about these weighty matters. You’ll barely even notice your feet. with plenty of soft DNA LOFT v3 cushioning and a GuideRail support system that seamlessly guides your foot on a natural motion path.

An increased rocker geometry and beveled heel add to the smooth transitions in this stable running shoe for an effortless ride. All you have to do is lace this shoe up and let it guide you through your next run.

WHAT’S NEW:

The Brooks Glycerin GTS 21 takes what runners have long loved about the Glycerin GTS line and dials it up a notch.

First. the nitrogen-infused midsole cushioning feels improved. In the Glycerin GTS 21. Brooks’ DNA LOFT v3 feels light underfoot and noticeably softer than the foam of the same name in the Glycerin GTS 20.

And there’s more of it. It’s so light that Brooks was able to add 2 mm more cushioning the midsole without a noticeable increase in weight – in fact. the Glycerin 21 is lighter than the 20.

Additionally. a more noticeable rocker shape creates a smoother ride.

Around the foot. a new warp knit upper mesh and an incredibly plush tongue create a more flexible fit while retaining the Glycerin’s trademark plush feel and secure lockdown. GuideRails cap off this shoe for a ride that is supportive and soft at the same time.
