Customer Reviews Brooks Glycerin 21

I love all my Brook shoes I have bought. Adrenaline is my favorite.

I really liked the 20 model except the narrow toe box so I was hoping Brooks would improve this. I did think the toe box was larger on the 21 however, the entire shoe felt roomy making it feel very sloppy on my foot. Also, it was super clunky....the larger soul that balloons out around the shoe kept hitting the inside of my opposite leg while running. It felt like the shoe was just too big and clunky feeling like it was running me as opposed to me running the shoe. Dislike and returned.

Ive worn the glycerin for years and run several marathons in them. I dont have a sneaker rotation i train and race in the same shoe, until now which Ill address in my Ghost Max review. Im a black sneaker person so the color options arent an issue. I was very much looking forward to the Gycerin 21 and I havent been disappointed just not wowed. It feels a bit flatter and not as cushioned as I expected, but adequate. A bit too roomy in the heel. Im a neutral runner and havent had a toe box issue but my left small toe feels a bit squished and uncomfortable. I wear a 9.5 womens, although in the Gycerin 19 I wore a 9. 57 years old and have been running most of my life-not an expert just a run happy, run for headspace and being outside and all the amazing benefits of running. I purchased the Ghost Max at the same time out of curiosity and thinking that would be my inside keep up with grandson shoe if I liked it. I will review that shoe also.

Compared to the last model I find that my pinky toe is rubbing even in a wide. Such a bummer because the glycerin 20 was my go to marathon shoe! Please fix toe box in next model!!!

I have probably owned at least ten pairs of the various versions of this shoe. However, when wearing these shoes the stiff part of the front of the shoe near the tow box has creased creating a very sharp indent that hurts my feet when I walk. Its the area where the tongue is sewn in. It digs into your foot and makes it impossible to wear. I even tried a high a size bigger to see if that would help. Ive tried stretching the shoe but its too stiff and wont budge. I have stopped wearing them because of this. This happened almost immediately. Too expensive to be so bad. I guess I will finally be switching brands. I have no choice.

The back of the heel is shorter in height and doesnt cover as well as previous models. Kind of odd to make it shorter because it feels like your foot isnt all the way in. I compared it to my 19 &20s and its definitely shorter. Size & fit is the same as previous glycerin. Stiffer at first than previous models. Just ok not my favorite glycerin.

I like these a lot! They have a lot of cushion and for me these are my go to shoes for my long runs. I did my first marathon at Disney with these and I had no blisters or any other issues with my feet!

Love the extra cushioning. I have been wearing Glycerins since the 10. I love this latest version. To me, same fit as the 20 but extra cushion. This ole girl with the joint replacement in my big toe loves these shoes. Look forward to more color choices.

These are WAY better than the previous two versions. They're soft without being too soft and so comfortable. I feel stable while running in these and they barely needed any breaking in. I have high arches so added Currex insoles to these and could not be happier.

So much cushion! Neutral color and pattern that matches everything.

I've gotten the Ghost series in the past. This is my first Glycerin series shoe and I do like it! It's roomy for my EEE width feet, cushiony for my concrete work flooring and takes some of the shock off my "oh-so-sore" knees. I'm very happy with this purchase!

Just finished my first run in my new Brooks Glycerin. They were great. They are light weight and the perfect amount of cushion and support. Bonus, I shaved a few seconds off my mile!

These feel great but they run larger than previous years' Glycerin models and they are quite wide at the toe. I've been buying Glycerins for years, and I've had three pairs of 19's because I like them so much that I keep ordering them. But I wanted to try these. I've always ordered size 10 in these for my size 9 foot as they used to run small, but these 10's are at least a half size too large for me. I will either exchange them for 9.5 or return them. Not sure I like the wide look although maybe I just need to get used to it. Also, they didn't have any colors that I loved, so I bought the beige ones, and maybe the light color makes them look even bigger. They are super comfortable and I'd be interested to see how they are for running if I decide to exchange vs. return. I'm sure they feel amazing to run in, very cushy.

I bought this shoe last week and love it. Its a nice update to the Glycerin 21. Good tread and nice wide platform for stability. Good grip. I think the tread is better than on the prior version. Color ways could be improved, however. The shoe definitely feels good. I wear the same size as I did in the Glycerin 20 model. The fit is similar, but I get a better lock down in the heel.

Great fit, comfortable, almost eliminated my plantar fasciitis after a week of wearing them!

I think this is a great update to the Glycerin from the previous 20 version. I use these for running, and find them appropriate for long runs, as well as speed work. They are very cushioned, yet lightweight. I run outdoors in all conditions & surfaces (dry, wet, snow, pavement, gravel, dirt, etc.) and have found them to be very stable with decent traction. The wider base offers extra stability as well on trails and uneven surfaces. I have average width feet - and find these to have ample room in the toe box, for those long distance runs when your feet tend to swell a bit towards the end. Super comfortable! They were comfortable right out of the box. They seem to be true to size, as I stayed with the same size I always wear.

Very comfortable shoe. After running in the Glycerin for several years the Glycerin 20 didnt work as well. The 21 is working great

I dont like the 21 as much as the 20. 21 It has more cushion compared to 20, but the sole rubber goes up a little high in the side of my feet rubs on my Taylors bunion. I liked better the simplicity of the 20 because they are my everyday shoes (white and grey colors), the sole is not high on the side and they are more stylish. Im desperately waiting for the grey-white ones to come out. I shift between the Medium and Wide models. Definitely the Medium 21 has less room in the toe box than the 20 and the Wide 21 has too much fabric on the toe box and my feet moves around. (I resorted to wear thicker socks). Disappointed.

Dont like them at all. Have worn glycerins for years. They are too soft. The heel is too low. Less stability. Doesnt feel like a Brooks sneaker .

Good amount of cushion in the heel, but also provides stability. I bought my normal sneaker size.

The bottoms were a bit tacky on walking surfaces. I'm thinking it's due to being last year's model and sitting on the shelf in a warehouse too long possibly in suboptimal conditions. Not thrilled with this purchase.

I like the Glycerin 20 much better. The fit was better and the blue color much better.

Eh it's okay . Was expecting something more but I get it . You can't always get what you want but you can try sometimes and you get what you need.

I love brooks shoes!!! But these run a little small and narrow.
