BrooksMen's Glycerin 21 Running Sneakers from Finish Line

I recently picked up the Brooks Glycerin 21 after my go-to shoe, the Brooks Adrenaline, was out of stock. I was told the Glycerin was a good alternative, but unfortunately, it didn’t live up to that promise—at least not for me. Right out of the box, the Glycerin 21 felt plush and well-cushioned, which initially gave me hope. However, once I started running, the comfort quickly disappeared. The fit felt off, especially around the arch and heel, and I noticed discomfort within the first couple of miles. After a few runs, the pain in my feet became consistent enough that I had to stop using them altogether. To be fair, the Glycerin 21 might work well for runners who prefer a softer, more neutral shoe, but if you're coming from the Adrenaline—especially if you rely on the stability features—it’s just not the same experience. I felt like I had less support, which may have contributed to the discomfort during runs. Overall, I wouldn't recommend the Glycerin 21 as a substitute for the Adrenaline, especially if foot support and comfort are high priorities for you. Hopefully, the Adrenaline comes back in stock soon because this one just didn’t work for me.

Good fit and feel.

I've gotten in about 10 outside runs (3-6 miles) now. Good fit and feel. I am more of a stability and support guys versus super cushioning. It's been my new go-to pair.

Great buy!!!

Great shoe!!!

Love the shoes. Colors are great. I have 5 pair now and wear them all the time.

Best running shoe I've owned. Able to run faster and longer.

Good Shoe but won't be buying again.

Heel placement felt insecure, foot seemed to slide around in the base. Most likely lighter runners won't experience this I'm 6ft 230. Cushioning is amazing and definitely lowered the impact on the body even from concrete paths.

Like a cloud

Love them wish I had a pair of red ones that come in my size. 11.5 wide. They are comfortable and like walking on a cloud

Comfy shoes

The shoe is fantastic, comfortable and amazing to walk and be well all day long. I bought them for trip overseas, and we will be wearing them a lot soon. I always buy 1 size up and wide for extra comfort.
