For years, having supportive running shoes meant a posted piece of dense foam nested against the medial side of your foot, helping prevent excess motion. But things are changing in the world of running shoes, and the Brooks Adrenaline is leading the charge.
Rather than sticking with the same old, the new version of the Brooks Adrenaline utilizes a “holistic GuideRails support system.”
Rather than trying to lessen excess motion in the arch/midfoot area and stabilize the foot, the Adrenaline GTS 19 works to guide your movement by addressing the knees. GuideRail technology on either side of your foot help guide you through your heel-to-toe, keeping everything aligned in the process. That means that the shoe feels more flexible and natural, which is never a bad thing!
To visualize this a little more clearly, think about the last time you went to a car wash. You get your car onto the rails, and then you can put it in neutral and not worry about veering off course. Similar basic principle with Brooks GuideRails. The guiding pieces on each side of the foot will ensure that all you have to think about is putting one foot in front of the other.
