Customer Reviews Brooks Glycerin GTS 21

Why so different from the previous model?! I have been wearing the Glycerin GTS for a few years and have loved them, run several marathons in them and had no issues. I recently got the updated version and immediately noticed how different they look from the previous version. I started getting pain in the balls of my feet within a few miles of the first use. I switched back to the previous model and had no issues. I've tried just using these as walking or every day shoes and the same thing happens. I'm not sure what is going on, but this is not the same shoe as the previous model at all. It's frustrating when shoe companies do this!

Amazing support cushioning most comfortable athletic shoes ever. I work in Outpatient physical therapy and advise patients who experience foot, knee or back pain about proper fitting supportive shoes. Brooks are my new favorite!! My coworkers therapists also wear Brooks. I ordered 7.5 as my first trial but wonder if size 8 would fit better. I have low arch and small bunions. I enjoy walking my dogs. No pain in Brooks shoes compared to my old shoes Skechers or Ryka. Pretty lilac color

These are very comfortable and, in my opinion, true to size. I have back and neck pain and these were highly recommended by the internet. Unfortunately after only a few wears, both shoes have indented in the toe box and although it doesnt look like much, it is severe enough to hit my big toe and causes annoyance to the point that its all I can focus on. I am on my feet about 60% of my workday and Ive worn these on one outside walk in moderate/warm weather. I have tried to correct the indent but no matter what I do, it always ends up popping back into the dented position. Due to this I cant recommend and wouldnt purchase another pair.

I have been a glycerin wearer for years and have been really disappointed in the quality of these shoes! Like others, I had the issue of the toe box collapsing in certain spots, putting pressure on certain toes and making my workouts super uncomfortable. In addition, I got these on April 8th and the tread on the shoes is already completely worn down on the ball of my foot. I use these for walking (not every day) and for indoor workouts, so I am shocked that they have worn out so much in 2 months. I usually get about 4 months out of my Brooks. I do high impact workouts, so usually they lose cushioning, but I have never had a shoe wear down so quickly in other areas. The cushioning also seems to be breaking down pretty quickly. I feel ready for a new pair and its only been about 2 months! Super disappointed and honestly not sure which shoe to buy nowI need new shoes, but I really dont want to keep dropping $150 every 2 months and with these being newly released I will be waiting for a long time. I hope Brooks brings back the quality!!

Love the cushion and support of these and the bright pink color is beautiful! Great room in the toe box. My issue is that on BOTH shoes, the big toe area bends in on the front side and is painfully digging into my big toe when I walk. My pair of the previous version didnt do that, so I dont know if its just an issue with this particular pair, or with this model in general.

I was excited to get these shoes, the moment I tried them on I immediately bounced around to test how cushy they were. The soles have an incredible thickness to help people on their feet a lot, whether its walking, running, other exercises, or long days at work. They were incredibly tight on my feet at first, but after a few days of wear walking through theme parks, they stretched a bit and formed to my feet very well. They are very supportive and incredibly comfortable.

I purchased two pairs of the Glycerin 21 style in Spring 2025 to supplement my Brooks Ghost 15 shoes, which are no longer available. I wear AFO braces and have found the Glycerin to offer slightly more comfort in the heel because of the outer heel style and perhaps a bit more slope of the sole, heel to toe, than the Ghost. The Glycerin seems slightly more snug across the toe box than the Ghost, although not enough to be uncomfortable. I generally order from the company website because the braces require a size 10 wide and I like color and design choices.

Best pair of Brooks shoes I have purchased. I walk 5 miles daily in 1 stent and have owned numerous pair of Brooks this is my 1st pair of glycerin and love them.

So comfy and don't make my feet hurt

My knees have stopped bothering me when I run (I waited too long to get a new shoe). Very nice support. Comfortable. Wish they were a bit lighter, I have been using Brooks running shoes for years.

Very comfortable and I like the style.

My first Glycerin.I have many, many other Brooks shoesbut Glycerin may be my new favorite! I need the GTS shoes so I was disappointed with the color choices offered in GTS. Additionally, the GTS versions often sell out quickly . I'd like to see more color selections in large enough numbers to have them available for purchase. (Personally I did not like the " Miami Vice" version).

Love the shoes. Also have a pair in black.

The fit is consistent with Brooks,which is great. Good cushion. Good toe push. Comfortable heel.
