Great shoes!
This is my second pair of these shoes, and I wore the bottoms off my first pair. I have a feeling I will do the same with these. I walk a lot, and they are comfortable and give me both stability and cushioning with each step. I have wide feet, and these fit perfectly.

New Favorite!
I used to swear by the Hoka Bondi, but these completely won me over. Super comfortable, supportive, and lightweight—perfect for long runs. I trained for and ran my first half marathon in them, and they held up amazingly. Definitely my new go-to running shoe!

Runs extra small
This Glycerin GTS 21 shoe is super comfortable and super supportive. However, it appears to run half size small. I ordered a Brooks Launch 9 running sneaker style in a medium size 8, about 3 months ago and it fit perfectly. But this GTS 21 syle was half size too small so I ordered a 8.5 size and it fits perfectly. My normal shoe size is 7.5 but in ALL sneakers (Sketchers, Ryka) the company tells you that it runs small so I have been ordering size 8 for all my shoes and everything has been fitting fine with a size 8. This is the first time I have had to order a size 8.5. Some reviews of this shoe did say this ran small; hence why I ordered an 8. But 8 was not long enough in this style. I could fit into the shoe but my toe came right to, and touched, the end of the shoe. I was afraid when my feet swelled in the summertime, the shoe might not be comfortable. I am in my 70s and have no cushioning on the bottom of my feet anymore so I need a shoe that has good cushioning to exercise walk 3 times a week or just walk when I am shopping. Normally, I end up adding a cheap chushioned insole in all of my sneakers no matter how much cushion the company says the shoe says it has but I will not need to do that to this one. I would order this again.

excellent cushioning and stabilizes your gait
Let me start by saying I can't believe I paid $160 for a pair of sneakers. I've been hiking/walking on my treadmill for 3 months now, and have been fighting plantar fasciitis in 1 foot. After talking with a doctor, it was revealed that I under pronate (supination) when I walk. Putting the weight on the outside of my foot, instead of the inside where it belongs. That explained my clumsiness when trying to run, I was all over the treadmill every time.It was suggested that I get some really good supporting sneakers. Either the Puma deviate Nitro or these Brooks. After reading reviews, I decided to give these Brooks a try.These sneakers are awesome! They are lightweight, and they are very cushioning, yet flexible. They are very stabilizing, and the first time with them on the treadmill I was able to run.And the best part? NO PAIN. NO PLANTAR FASCIITIS pain afterwards. Not even at the end of the day.They look to be well made, and I expect to get a lot of use out of them. Well worth the money.I'm already picking out my next color!

Runs short/smaller in the toe box, order up 1/2 size
I'm a fan of Brooks as I over pronate. I've bought the Ariel and Adrenaline in the past, but the last 3 years bought Adrenaline GTS. I wear a 8.5W Women's, always buy one pair and keep a second new in reserve when the first wears out as difficult to find my size and preferred colors. Reviews of the Glycerine GTS 21 Supportive stated best for over pronation but reported smaller and tighter in the toe box recommending sizing up, so I did: 1/2 size to 9W. I agree with reviewers. Amazon also reported many are returned (perhaps due to sizing issues?). Just arrived, have plenty of room in the toe box and don't feel any issue around my big toe regarding rubbing (see customer reviews), will wear in the house today to insure issue doesn't arise. Otherwise, very comfortable and not much longer or bulkier than my Brooks Adrenaline 8.5W. Purchased Used/Like New so arrived without box but otherwise looks unworn, excellent savings so pleased with purchase.
