Product Description 
Adrenaline GTS 21 is found in the cushion segment of Brooks’ line. Being a mild stability shoe providing holistic support it contains Brooks unique GuideRails technology. It addresses both the foot and knee relationship and provides a “coupling” that reduces excess rotation.   Rotation starts at the feet and works its way up the leg to the knees. GuideRails keeps you in check yet allows you to run according to your biomechanics. Adrenaline 21 contains both DNA LOFT which is super soft and quite light weight and BioMoGo DNA. Unlike version 20, the 21 has the soft DNA LOFT cushion extended on the lateral side of the shoe from the heel to the forefoot with BioMoGo foam in the rest of the forefoot. This allows for a smooth transition, soft cushioned feel, and a more responsive foam in the BioMoGo allow for more efficient toe off. Combined they provide just-right softness underfoot without losing responsiveness and durability. There is an extra layer of EVA foam found just underneath the footbed, on top of the midsole for extra cushion. The outsole is high abrasion/air blown rubber which helps reduce weight yet is very durable. The Adrenaline GTS 21 upper is a soft, with plush engineered mesh providing an excellent fit. It comes with a 12 mm drop and is a mild stability workhorse yet well cushioned training shoe. 

Running Niche Experience 
We find the Adrenaline GTS 21 fits true to size in all aspects. If you have used the previous Adrenaline GTS 20 you may feel that it fits slightly more generous in the forefoot but still has a nice snug fit through the mid-foot. This is due to the updated engineered mesh and overlays through the mid-foot. The collar surrounding the Achilles is soft and comfortable. It is a slightly stiffer shoe, more so than a neutral trainer and as such provides a real smooth transition from heel strike to toe off with the GuideRails to help you maintain good running mechanics.  We also notice that because Brooks uses GuideRails instead of firmer medial posting, the GTS is well cushioned with their softer DNA LOFT foam extended though out the whole shoe. 21 is a nice improvement over version 20 as it is a bit lighter and the cushioning is softer. This is a solid medium to high mileage shoe easily handling 50+ miles a week type of training shoe.   Stack height is 32.0 mm in the heel and 18.0 mm in the forefoot. 

Technology: DNA LOFT, DNA AMP, BioMoGo DNA, GuideRails™ 
Brooks’ core technologies focus on the midsole with several different foam combinations providing different characteristics depending upon end use of the shoe. In addition, they have a unique approach to support called GuideRails, which is found in their stability-oriented shoes. 

  • DNA LOFT provides our softest cushioning yet. It instantly adapts to the runners’ individual stride, weight, and speed with a unique blend of ethylene-vinyl acetate (EVA), rubber, and air. The rubber adds longevity to the EVA midsole, ensuring softness. While the air decreases the shoe’s weight. DNA LOFT is engineered to be lightweight and ultra-soft, without sacrificing durability or responsiveness, making it our most luxurious shoe technology yet. 
  • DNA AMP is a polyurethane (PU) based cushioning system designed for energy return. It does this with a foam that naturally expands as force is applied. To deliver an amplified experience, we encase the foam in a thermoplastic polyurethane skin that resists horizontal expansion. The result is a springy ride with best-in-class energy return. 
  • BioMoGo DNA adapts to your specific weight, pace, gait, and running surface. That makes for a springier step that’s customized for your stride. 
  • GuideRails™ technology delivers on-demand support, allowing your hips, knees, and joints to move the way you naturally do. Think of GuideRails as bumpers in bowling. When your stride falls out of place, they kick in to guide your stride back in line. They’re there when you need them and out of your way when you don’t.
