Brooks Glycerine

I have been recommended these shoes for my extremely arthritic feet by professionals. They are a replacement pair and they are the only shoes I can wear comfortably for lengthy periods.

Great Shoes

These are much smaller than the Glycerin 19 and Glycerin 20

Wouldn’t Recommend

[This review was collected as part of a promotion.] Not a very strong, structured shoe, pretty flimsy if you wear orthotics and need support

Once You’ve Tried These, You’ll Never Go Back

These shoes give my feet - and joints - the perfect cushioning and support I need, whether I’m wearing them around all day or at the gym. I will never wear another brand now i have these

Love My Brooks!

Love my Brooks, second pair of same model. They are so comfortable and great support!

Glycerin Comfort With Afo Braces

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.

Glycerin Gts21 Black

Glycerin GTS 21 Black. These did not feel as cushiony as prior purchase. I tried a size up to allow running room and got blisters.

Excellent Support And Fit

Runners feel like clouds with lots of protection for arches

LanaD

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.

ANAC

I love them! I have been running in Brooks for some time and these feel like they have the right amount of cushion without feeling like you will twist your ankle. I got them for my first Hyrox and they did great - only thing is that if you do not tie them up good, they slip on the sled pushes. For running, they are great!

MinetteG

I purchased these because for some reason the 20's were discontinued? They don't fit as well as in they are tighter and for some reason shorter? I will never use them for long distance or prolonged usage. I will keep them as an emergency backup. But would not purchase them again. Still trying to find a replacement for the 20's

Great Running Shoe

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.

Good Shoes For Hospital Workers

Excellent shoe for working in a hospital. I do a lot of walking and standing in the IV room and these provide tons of cushion and support. Love the color combo too.
