Product Details:
With even more nitro-infused foam than before, the Brooks Glycerin 21 returns to deliver an ultra-comfortable and smooth ride for any distance.
In this update, the Glycerin 21 adds 2mm more plush and responsive DNA Loft v3 foam into the midsole, offering a little extra softness to a shoe that's already plenty soft. As a cherry on top, the additional cushioning does not come at the expense of extra weight. On the contrary, the Glycerin 21 weighs almost an ounce less than the previous model!
Bringing long-lasting traction to the party is the new RoadTack rubber that is strategically placed in the outsole to deliver the grip needed to rack up the miles. This shoe is rounded out with a new engineered warp knit upper that checks the boxes of being accommodating, secure, and breathable, which only adds to the supreme comfort the Glycerin brings to the table.
Running farther has been made easier than ever thanks to the Brooks Glycerin 21––all you have to do is enjoy the ride.
What You’ll Love

Customer Reviews
Wifey Love themBought these for my wife. She was a Hoka Clifton gal, but wanted a more durable option. These worked out perfect so far. A little more weight but she isn't really a runner, more of a speed walker. So win, win. Thanks for the great service at RW. Best in the biz

Brooks always deliversThese were a gift to my girlfriend. She’s new to running and she wanted a highly cushioned shoe. She’s only tried 3 other running shoes from different brands so far. She went on her first run with the Glycerin last week. She’s enjoying the shoes so much until she told me to get another backup pair for her birthday next year lol. I guess it’s safe to say that she’s now a big fan of Brooks!

Another stellar releaseI have been buying the Glycerin series for many years now and they keep getting better. I thoroughly enjoy this version. You'll notice the quality detail and workmanship. They feel great during the run.

Brooks Glycerin 21Size is perfect and is very cushioned. So far the tread ware is a lot better than other brands. I would recommend and will buy this shoe again.

Glycerine 21It has high cushion and perfect for daily running! Not heavy and pretty breathable. I got wide but i wish they had more color options for wide. Design and color is far less pretty than other brands.

Brooks 21Shoe is heavy. Good for a walk but feels like a lot to carry on the feet. I would not buy again.

Great ShoeReally nice shoe. Very comfortable and good support. Not heavy either. Shoes with good support and lots of weight drive me crazy. Can hit some of my steady pace (6:00/mi) work in them as well. Big fan

Great feel and cushionngI rarely switch shoes or models once I find one that I really like, but I had developed a dull ache in my ankles and feet that I just couldn't shake. I did some research on shoes that were similar to my previous model, but with a bit more cushioning. I was a little bit concerned with heavier shoes, but this model is absolutely terrific! If I occasionally switch on and off between this model and my previous shoe, the difference in discomfort is immediately noticeable. I am sure that I will be stocking up on the Glycerin shoes with future orders!

Great Comfort, but......Brooks have for many years has been my go to. The Glycerin 19 I put over 800 miles on a pair, the 20 I put over 900 miles on a pair and their was still total rubber on the sole.
The 21's in my opinion were a step up in comfort but wore out extremely fast. The first I got lasted to 400 miles, the second pair is toast at 300 miles. The 21's are great comfort but wear out very quickly.

Best shoes ever!I have worn this shoe for decades, yes I have tried others. Don’t know why I did as they were always failures. I always end up coming back to these fabulous shoes. I really love the fit of the newest model as they returned to the one they had a few years ago. I like a shoe with a wider square toe box and the cushion in these shoes are perfect!

The right kind of squishy for a big runnerTo give a reference point , I’m 6’4” and 310lbs. My runs are normally 2-3 miles with anywhere from 11:02 to over 13:00 minute pace depending on what kind of run it is. These have just the right amount of give, doesn’t feel like it’s sapping your energy but also doesn’t feel like your shoe is bouncing against you. Definitely my new favorite shoe, been wearing Brooks for years and have run in Hoka, Adidas, Nike, Saucony, Asics, NB, and Mizuno; keep coming back to Brooks and these are the best they’ve made for me.

Comfortable from the beginningRecently I needed a new pair of shoes. I went to Run-n-Tri in Gulfport, MS to a computerized fitting. After my firing I tried on the Glycerin and found it to be very comfortable. My heel was being held in place. As I walk the bottom of my foot receives a gel-like feeling that makes it an enjoyable experience. I am very pleased with my purchase.
