The Brooks Adrenaline GTS is one of our most popular running shoes at Run4It. They might just be one of the best stability running shoes ever made. Now on its 23rd edition, the latest Brooks Adrenaline features the most cushioned underfoot feel to date. This is because the Brooks Adrenaline GTS 23 has been updated with DNA LOFT v2. The fit on the bridge of my foot felt a little too snug at first, but once I started moving, I was pleasantly surprised at how the gusseted tongue and laces flexed as my foot did, allowing for a nice smooth transition by preventing any restriction, rubbing or tightness.

Having been in the shoe game for over two decades, Brooks is amongst both the oldest and most successful running shoe companies globally. Their specialty is producing durable, everyday trainers with their innovative technology and specialized cushioning. I have/had Adrenalin GTS 19/20 and now bought a pair of Adrenalin GTS 21 US12/46EU size (Blue/Red color). Never used first once on both feet. If I slight put weight on the toes the TOE Box mesh material collapses on both sides (Only left shoe). My real foot size is 28.5CM so the 12″ is 1.5″ Size above. There is enough room for the toes. The durable midsole provided a firm yet responsive ride. The GuideRail system cradled my feet as I ran in them giving me the right amount of stability when needed. One aspect of the shoe I liked was the width. It isn’t a tailored fit but it gives your feet room to feel and splay out naturally. This natural feeling is extended to the engineered mesh because of its flexibility. The drop of this shoe is 12mm, being 1mm less than the previous GTS 20, but still much higher than the running shoe average drop of 8-10mm.Guide Rails support system encourages natural motion of knees and hips, reducing chance of injury over time During gait analysis you will be asked to walk and run on our in-store treadmill whilst your movements are recorded using the latest Daftfish software. A slow-motion, detailed analysis will show and explain your biomechanics, specifically looking at pronation, the inward-turning movement that occurs when your foot touches the ground. During walking and running this acts as cushioning for the body. I knew from experience Brooks trainers take a little longer to break-in. The drop was also evident, it is a 12mm drop in both the mens and womens. From time to time carriers may deliver earlier or later, or on non working days however this is cannot be guaranteed nor should it be expected.

Segmented crash pad flexes with the foot, offering customized cushioning and stability for a smooth heel-to-toe transition. Saying this, it still felt pretty soft, nicely responsive, and only got better the more miles I ran. The firmness was definitely noticeable at first, but after a few runs, I found that the foam broke in nicely, becoming more supple. It was actually running on these uneven surfaces that I could really appreciate the GuideRails Technology. I’m a mild overpronator, and running on unpredictable surfaces often seems to make this worse, but my foot felt really stable and supported throughout. Blown rubber is found on the outsole of the Adrenaline. It is built to last hundreds of miles. Omega flex grooves are strategically placed on the outsole to give flexibility to the shoes. This a productive factory construction error in the upper mesh material (Print) they have. There are a few blogs which mention that there must be a newer version of the shoe.We’re coming to the end of our Brooks Adrenaline GTS 21 review – so, what are the key takeaways, and who should/shouldn’t buy them? It was a reliable ride whether it was 2 miles or 12 miles. The midsole was built to last for hundreds of miles.
