Packed with Lightweight, Nitrogen-Infused Foam Cushioning
Experience cushioning like you have never felt before with the Brooks Glycerin 21. Packed with more of Brooks’ high-performance DNA LOFT v3 midsole foam you will appreciate the way the shoe absorbs the impact from the road. The Glycerin 21 has been one of the best high-cushion running shoes on the market for years, and the newest version of the Glycerin will not disappoint.
Once you step into the shoe you will notice a new and improved upper that has been streamlined to reduce irritation and improve the fit of the shoe. This combined with a broad underfoot platform to ensure a secure transition means your foot will remain stable and every stride feels smooth and soft.
Brooks also makes some of the most sustainable running shoes available and the Brooks Glycerin 21 does not disappoint with the upper being made from 59.7% recycled materials which diverted 4.1 plastic bottles from landfills. Whether you are using the Brooks Glycerin 21 as a walking shoe, training for a marathon, or anything in between you will appreciate the plush cushioned feel underfoot to keep you moving in comfort.

- DNA LOFT v3: A soft, light, nitrogen-infused EVA midsole foam built to increase cushioning and reduce weight.

- 28mm/18mm Stack Height: The Glycerin 21 has 2mm more midsole foam than the Glycerin 20 while reducing the overall weight of the shoe.

soft and durable
I am a beginner runner with an above-average BMI. This is my first serious running shoe that meets my expectations from all aspects. Great companion, love it!

Really great shows
I started running again and have done several 10k runs with these. Really comfortable and light. Would totally recommend them.

Survived a mud run
Wore them on a mud run because I needed something for my heel spur. They survived the mud and the foot felt great.

Amazing
Who knew that as a woman, I needed a man's shoe? Well, the helpful salesperson at Marathon Sports helped me to realize that my widening mid 40s feet didn't need a new running shoe style (though we tried on about 10 other brands/styles), but the trick was just sizing up to a man's shoe which did the trick. This shoe is so comfortable and cushioned.

Had to Return
Unfortunately they did not fit my dad’s foot well. I returned and still haven’t received notification that you received them. Hope to get that soon with the refund. Thanks.

Poor Fit
I’ve had earlier versions of this shoe and was very happy with them. While the sole and cushion in the shoe was great, the tongue is sewn into the shoe and was cutting into the top of my foot. I’ve retired this shoe after only 15-20 miles of running and have switched to On.
