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 runner in our Brooks Glycerin 21 review, describes 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

You will love the comfort and softness that the Brooks Glycerin 21 provides for any and everything you do in it.

Happy 3 mile 4 day/wk rinner w wide foot

David M 3 months ago Verified Purchase

Love the Glycerin size 10 wide for men 10 mm drop extra cushion. My first extra cushion shoe. The fit is great the cushion is great. Liking the fact that my usually sore always wide right foot is comfortable with the width and the cushion. Also have had history of calf strain but for whatever reason (could be the 10mm drop) no issues.

Show are very comfortable but they got wet the first week and I put them in the dryer. The dryer left melted spots all on the sole so don’t dry them!!

I have run in a previous version of Glycerins. These fit perfectly and have the right amount of cushioning for longer runs. May order another pair soon.
