REVIEW: Brooks Adrenaline GTS 21

The new Adrenaline includes more DNA Loft foam and a super breathable upper

For years, the Brooks Adrenaline has been a staple stability shoe in the company’s lineup. As a runner who typically wears a neutral shoe, when reviewing one that falls in the stability category, I tend to notice that my foot is moving differently as I run. However, this wasn’t the case with the Brooks Adrenaline GTS (which stands for go-to support) – it’s supportive without being (noticeably) corrective.

The Adrenaline GTS 21 has a few key changes when compared to the 20. Those are the extension of their DNA LOFT foam through the entire shoe and a lighter, more breathable upper – both welcome additions to a reliable shoe.

The upper

The Adrenaline’s upper is made with Air Mesh to keep things breathable and flexible. The laces also have a bit of elasticity, meaning that you can tie them tight without restricting your movement. While this shoe would be a great treadmill or warm-weather buy, due to the mesh upper, it’s not ideal for running outside on snowy days. 

GuideRails (a.k.a the midsole)

Instead of building up the foam along the inside of the shoe (with what’s traditionally known as posting) the Adrenaline uses the Brooks GuideRails to keep your foot in line. GuideRails keep your foot from excessively moving without actually correcting it. Basically, they reduce the movement options for your foot, without locking it into one position. Think of them like a fence for your yard, or a rumble strip on the highway. 

The GuideRails are coupled with newly extended DNA LOFT foam through the lateral side, which now runs from the heel all the way to the toes, and the BioGoMo foam, which runs through the medial side. These three midsole components make for a firm but smooth ride.

The outsole

The outsole held up well on dry roads and loose gravel. It’s made with traditional grooves and durable rubber to easily last over 500K. Brooks didn’t reinvent the wheel with this outsole, and when something works, it doesn’t need to be changed.

Final thoughts

Because of the GuideRails, this is essentially a neutral runner’s stability shoe. The GuideRails are a flexible form of correction, so if your foot isn’t out of line, you won’t even notice they’re there. It’s great for someone who overpronates or supinates, but also can work for a neutral runner.

This shoe is ideal for someone new to running (who might not be sure if they need a stability shoe) or a person who likes a firm feel and wants a reliable everyday shoe. If you’re in the market for a new trainer, this shoe can easily hold a place in any runner’s lineup. Extra widths are also available and the shoe comes in 10 different colourways.
