Right now the industry is trending towards softer shoes and away from traditional methods of reducing overpronation. With the Adrenaline GTS 19, Brooks did an excellent job of catering to these trends. The ride is now softer, springier, and a new guide rail system helps to protect your knees by reducing excess foot movement.
To create a softer ride, designers blended air and rubber to the foam in the heel. The air makes it softer and lighter while the rubber makes it bouncier. Additionally, guide rails on both sides of the heel work like bumpers on a bowling alley. As your foot attempts to move from side to side the bumpers guide your foot back to a towards the middle of the shoe where your stride is most efficient.
Finally, the upper features a slick mesh with a ton of breathability and stretchiness in the forefoot. In the heel and midfoot, 3D printed overlays provide added support for a secure fit. If your looking for a protective shoe to put some serious miles on, the Brooks Adrenaline GTS 19 is your go-to shoe.
