The Adrenaline GTS 25 is the best-selling stability trainer on the market, and its support still works the way Brooks' GuideRails always have: nothing intervenes until your movement drifts outside its usual path, then the rails catch it. This generation adds more nitrogen-infused cushioning in both the heel and the forefoot under the familiar 10 mm drop.
It suits you if you overpronate, have a history the physio keeps mentioning, or simply feel steadier in a shoe that holds the line on tired legs — while running like a normal cushioned trainer the rest of the time.
It is not a corrective device, and it is not quick. The GTS badge means guidance, not a medical claim, and at about 301 g the fast days belong to something lighter.
