Customer Reviews Brooks Adrenaline GTS 21

I ordered multiple sneakers & these looked good & were comfortable, but I chose to keep a different brand as they were a better fit. I returned these.

I ordered in wide & I don’t think it was necessary. Seemed comfortable, but we’re too floppy. Returned.

These are nice looking & comfortable. I am returning as they felt too loose in the toe box & I felt I needed a little more support.

I've been wearing Adrenalines since 2016, and the 21 model just fits differently - a bit longer and narrower at the toes with less cushion. I was able to mostly compensate by moving from a 13 to a 12.5 and going a size wider. We'll see how it wears, but I'm at least glad Zappos had the sizes available to enable me to triangulate a solution.

I have been a Brooks Adrenaline fan for years. I had to give them up between the 17s and the 20s because they just didn't feel "right" (they pitched me too far forward, arch was awkwardly placed, etc.) but the new 21s have made me come back! I even bought two pairs. The ride is not as cushioned as I remember, but they work fine for my runs. In comparison, I also bought a pair of Hoka One One Bondis and while those are supremely cushy, are by no means as wide in the toe box as the Adrenalines. The Hoka's gave me blisters between my toes because of the cramped toebox.

I am a long time Brooks shoe owner. I have had multiple Glycerin, Adrenaline and Ghost. Honestly the newer versions are not as comfortable as the versions from more than 3 years ago. I have had several difficulties with both the Glycerin and Adrenaline. They are both great for the first few months but they seriously degrade after. I didn't think that this Adrenaline would fail me like the Glycerin did. I hope the next version would be better. Another thing to note is that they looked great in the picture but once you see them live and up close, they are a bit ugly. I'll be passing on these Adrenaline and will see how the new Ghost fares.

The fit has less room that my Kayano 26s, but is much comfier. There's definitely a lot more bounce to the shoes and less pressure on my knees (also seems to have reduced my shin splints).

Replacing Beast 18 which over the years had become bulkier and bulkier. Nice and light without giving up on arch and heel support.

It was a very comfortable shoe but just a little too short. My big toe rubbed against the front of the shoe whenever I took a step. It wasn't uncomfortable when it did that, but I figured I'd be wearing a hole in it soon. I had also ordered Asics Gel Kayano 27 at the same time, which turned out to be perfect fit. So I returned the Adrenaline.

Apparently Brook has change their engineering somewhat as this style show feels about a half size smaller and narrower that the previous versions. Otherwise the styling is good .

Sizing was good. Shoe is runs more firm than GTS 20, but that didn’t bother me.
