Brooks Adrenaline GTS 21


The legendary Brooks Adrenaline is twenty-fun and celebrating with a makeover.

Fresh new colorways and cutting edge tech come together in the Adrenaline GTS 21 delivering the adaptive support and ideal softness you know and love.

Guide Rails support shifts the focus from the feet to the knees. The holistic support system reduces excess movement so your knees and hips can move more naturally to keep you running comfortably and to keep injury at bay.

DNA Loft cushioning is a staple for the Adrenaline GTS. Now, Brooks extended the soft foam from the heel all the way to the forefoot to maximize cushioning, making each stride buttery smooth. Add in BioMoGo DNA foam to the midsole for heightened responsiveness and you’ve got the perfect recipe for a balanced, smooth ride.

The brand new Air Mesh upper with 3D Fit Print technology is specially engineered to hug the foot for a breathable, yet secure fit. Clean edges and sleek colorways keep this classic shoe looking timeless and fresh.

The Adrenaline GTS 21 has arrived, become part of the legacy today.

Things We Love About the Brooks Adrenaline GTS 21:

  • DNA LOFT cushioning now extends throughout the midsole for an even smoother transition from heel to toe
  • Air Mesh upper with 3D Fit Print technology offers snug fit and exceptional breathability
  • BioMoGo DNA midsole brings heightened responsiveness to super-soft cushioning
  • Guide Rails support system encourages natural motion of knees and hips, reducing chance of injury over time

Best supportive sneaker

I have worn Adrenaline for many years because of the great support yet comfortable footbed this sneaker provides. Plus I like the many different colors they come in.

Smaller fit than Adrenaline GTS 20

The Adrenaline 20 were my first pair of Brooks running shoes and I loved them right out of the box so when I was approaching 500 miles on them I looked in vain to replace them with the exact same make/model. Having no luck, I ended up ordering the Adrenaline 21 in the same size as my previous 20 pair (9). The fit was definitely tighter than my 20s, particularly around the upper half of my foot and on my toes, and after a short run my feet were starting to feel tingly/numb. After reading a number of reviews it seems this tends to be a common issue (the material/build is a little more restrictive) and I saw a few other reviews that people had to size up 1/2 a size. Thanks to Fleet Feet's amazing return policy I brought them in and they were able to get me into 9.5. Definitely felt roomier (the employee recommended more space between the edge of your big toe and the shoe than I am used to) but felt great after my first run and will definitely be a keeper now with the correct size.

Brooks Adrenaline GTS 21

I love Brooks running shoes and my new Adrenalines are very comfortable. Just ran my second 5K of the year in them with no discomfort. Great shoes!!

Brooks Adrenaline GTS 21

I have a short, wide, high in-step foot. This sneaker fits me like no other. No breaking in period. I would recommend whole heartedly!

Keeps going forever

The Adrenaline is a go to for marathons or for any run I do longer than 10 miles. They give a well cushion and yet structured ride that does not feel too marshmallowy. They also still have a degree of flexibility and amount of energy return and I appreciate the slightly higher drop as well. A forever favorite!
