Customer Reviews Brooks Adrenaline GTS 21

Not as comfortable as expected.

Fit isn?t as good as the Ariel. ?

I miss the arch support and the sides come up higher on the ankle. The first few runs take some getting used to it. Just doesn?t seem to have as much cushion as it used too but still a strong, supportive shoe.

I don?t feel like the shoes are as good of quality as they have been in the past disappointed I have bought like 12 different pair seems as if the last two pair was not good quality

I like the previous GTS 20's better. This shoe has good support, but the toe box has been a bit stiff which has felt a bit awkward when running.

I love the arch support and the fact that they are so light. I ordered an 8 1/2, my normal size. They are quite snug across the toes, so I have ordered another pair but in a wide. I hope this works.

This shoe is not as comfortable as the 18 was.

Comfortable but not enough support for the arch.

It isn't that I don't like the Adrenalin I just prefer the Ghost. The Ghost is more comfortable.

Overall the shoes are good, but it would be nice to have more options to choose from. As always extra wide is only available in one color.

I got these in extra wide- my foot looks like a duck foot- incredibly wide across the toes and tapered to the heels. I sized up from a normal wide when I started getting blood blisters on the widest part of my foot. I wanted these to be perfect, but the heel is just too wide. They are fine for 30 minutes or so, but anything longer than that and my heel literally slips out of the shoe. If you have a wide foot all over, these will be perfect, but for me, these will be short runs only.

Comfortable but they feel bulky, they make my feet look huge compared to my other shoes

I feel the GTS 20 was a better version. I have been running for over 24 years. I usually run more than 5 miles a few times a week. I feel that the GTS 20 version had more support than the 21 GTS version. After my first 2 uses of running approx 5 miles in the GTS 21, my feet felt tense in the area right above the bridge, before the toes on the bottom of the foot. I am still using them trying too see if that changes. As I revert back to several of the GTS 20 version I have, can immediately feel the difference in the support that the GTS 20 provides for my feet overall.

The cushioning in this shoe is amazing. I felt like I was walking on clouds! For me, however, I found that there wasn?t enough side support to keep my over pronation in correct alignment. If my feet did not have severe over pronation this shoe would be a winner! Don?t be afraid to purchase this style based on my issues!

These are definitely a half size bigger than the last 3 years. There is a noticeable difference when placed side by side. The toe box is much longer. And my feet feel strained after wearing. Haven?t returned them yet , it may be too late. I do love the black and raspberry though great job on the colors

I loved the Adrenaline 20, but for some reason this update just didn?t work for me. It seemed more narrow, but a wide width didn?t fit quite right either. Disappointed but still love Brooks and their customer service! Ordered another pair of Transcends to rotate in.

Less comfortable on my foot than the 19's. Felt a little smaller in the toe box. I reordered 20's and they fit my foot better and feel great!

They feel really flimsy and unsupportive. Definitely nowhere near what I am used to when I get a new pair of shoes (for so much $$). I'm disappointed. Its the first pair I've ever ordered that I wasn't happy with.

Been running in Adrenaline shoes for years. The 21s, while light, are the most poorly made pair I have owned. Interior material did not hold up and insole started to rub before soles wore.

Too wide. Returned, my feed are not particularly narrow and the medium was swimming on me. I have worn the same size and width for years and the fit perfectly except this version.

The GTS 20 was very comfortable but supportive. It hugged my foot as I ran. The GTS 21 gaped at the sides, did not hug my feet well. Shoe laces too short to double knot. Very disappointed. This has always been my go to running shoe in the past.

The toe box was too tight and the cushion was gone in a week. My knees and feet hurt already.
