WHY PACERS CARRIES THESE SHOES:

As runners, we spend so much time beating up our legs with high mileage and tough workouts that we owe it to give them a little love from time to time. The Brooks Glycerin 21 gives them plenty of love.

Soft and lightweight DNA LOFT v3 midsole cushioning means that you’ll barely even notice your feet touching the ground. An increased rocker geometry and beveled heel add to the smooth transitions in this running shoe for an effortless ride.

You won’t totally forget they’re on your feet, but you’ll love the way they feel every time you run.

WHAT’S NEW:

The Brooks Glycerin 21 takes what runners have long loved about the Glycerin 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.

A more noticeable rocker shape also helps create 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.
