Read our review of the Brooks Glycerin 21


The Brooks Glycerin 21 provides you with miles and miles of softness and comfort.

This plush shoe is optimized for your comfort by being lightweight, responsive, durable and cushioned. Whether you are on your feet all day for work, enjoying a daily walk or training for a marathon, the Brooks Glycerin 21 transforms your experience, making the pavement feel softer and smoother as you put in the work. One reviewer in our Brooks Glycerin 21 review, describe the experience as "running in this shoe reminds me of jumping on a bed, with the same fun factor involved. It was plush and comfortable with just a bit of bounce back."


  • Upper - A new, engineered warp knit upper improves the fit and feel on your foot. It is breathable and flexible, while still being soft and secure.
  • Midsole - the new nitrogen-infused DNA LOFT v3 is added to the Glycerin and there is even more of it to give you a plush, durable and responsive ride. A broad platform makes sure you have smooth heel-to-toe transitions.
  • Outsole - New RoadTrack rubber on the outsole is lightweight, durable and includes recycled silica.

What’s New

Brooks made the new Glycerin softer and more sustainable. They added DNA Loft v3, a nitrogen-infused foam that is lightweight, responsive and durable. Designers added 2mm of the cushioning to make it plusher and more comfortable over the long haul.

A new warp knit upper improved the breathability, fit and feel of the shoe and the new RoadTack Rubber includes recycled silica, is lightweight and durable. The recycled materials in the shoe are the equivalent of five plastic water bottles.

Who It’s Best For

The Brooks Glycerin 21 is one of the best cushioned shoes and is perfect for those looking for a comfortable and plush ride to put in a ton of miles. It is great for standing, walking, walking/running and running.

Why You’ll Love It

Excellent Upper Outsole TOO MUCH CUSHION

Robin T 4 months ago Verified Purchase

Excellent updates to the heel surround. The heel area fits snugly with ample padding not to rub the achilles. The new upper is an excellent fit - roomy in the toe box but the upper fabric keeps the foot firmly in place. The Cushion underfoot is just TOO MUCH. Great for someone who is just standing all day but not for a runner looking for responsive shoe. The outsole is so soft it is causing knee pain and pain in the forefoot. The Cushion on the outsole of the Glycerin 20 with this upper would be perfect. Good for a short walk but not the 10 miles I do.

Best Glycerin yet

Karen 4 months ago Verified Purchase

I've been a Glycerin fan for many years and this is probably my favorite one. Super cushiony but still supportive.

Best version yet

Amber R 5 months ago Verified Purchase

Happy with the upgrades from the 20s. More cushion overall and added in the ball of the foot! I’ve worn 18 19 and 20 but these have been the most comfortable yet. Extremely light lace up position is comfortable and the toe box is wide and non pinching. I have a pair for work and another color for fun!

Shin splints went away

I recently joined Orange Theory and was getting shin splints from the running. I went to my local running store Georgetown Running and they recommended these shoes. My shin splints went away!

Didn’t know what I was missing!

Diana G 5 months ago Verified Purchase

These shoes are so comfortable and the support is perfect….it’s like walking on a cloud! I came home and put my old sneakers on and thought how could I have ever thought these shoes were comfortable?
