The Adrenaline GTS is a moderate stability trainer and it's just what you would expect from a Brooks trainer: it's simply a well-designed running shoe that doesn't try to be something that it's not. Its GuideRails® support technology will prevent excess movement without preventing natural movement. Your arches will feel locked in while a slightly wider toe box and midsole allow just enough freedom.
Along with moderate support, the shoe offers a moderate level of cushioning. Cushioning won't overwhelm you, and neither will the reduced weight that a mid-cushion shoe offers. And that's exactly what you want from a mid-cushion, neutral trainer.
