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.

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!

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.
