Review Analysis

9.3Overall score
Very good long-distance
Brooks has delivered dozens of times over the years with running shoes that perform. However, their latest model—the Adrenaline GTS 21—might take the cake for bestselling stability trainer. Touted for its smooth ride and adaptable support, the brand has done it again with a reliable, no-frills shoe geared for daily runs.

Perhaps the most notable feature of the Adrenaline is its stellar midsole. Its DNA Loft and BioMoGo DNA technologies provide the best of both worlds with the perfect balance of comfort and security. The cushioning makes it a great shoe for longer rides and daily use. The upper is breathable and supportive with an updated engineered mesh. Brooks has also continued implementing GuideRails support technology on their stack, extending it to the Adrenaline GTS. It's supposed to ensure that a runner's feet and knees remain aligned, providing as much security as possible. While we generally don't advocate for support shoes in the absence of probing scientific proof, some runners swear by it. Hence, it's definitely an option to consider if you're having difficulty finding comfortable shoes. The outsole's segmented crash pad is sturdy and lends itself to good traction so that runners can enjoy a secure grip on the road.

There's no doubt that the Adrenaline GTS is more than capable of performing as a stability shoe. In fact, it's one of the strongest stability options on the market. That said, runners shouldn't expect a noticeable bounce or lively spring with each stride. Instead, this Brooks model focuses on providing a smooth ride that's durable and reliable for your daily run. It's not recommended for sprints or faster workouts. Some users also suggested that a lower heel drop-off would be preferable.

In summation, the Adrenaline GTS does everything a good, long-distance stability trainer should. In addition to offering steady support, it's great for marathons and recovery days alike. Available at an average price for its caliber, it may just be the shoe for you!

I have overpronation. Are the Brooks Adrenaline GTS 21 good for me?

Yes, this shoe is a stability shoe, so it’s specially configured for overpronators. Anyway, no empirical data prove that stability running models are a better choice than neutral shoes to prevent injury.

Yes, this model should be a good fit regardless of your weight. Indeed, it has a comfortable cushioning with a 30-mm stack height under the heel, which is sufficient for most runners.

Is the Brooks Adrenaline GTS 21 a good choice to run a marathon?
