The Brooks Adrenaline GTS 15 is a lighter, more stable and more flexible update to the Adrenaline GTS 14. It has achieved this by using a blended DNA BioMoGo midsole, and improving the uppor system. The dome toward the heel has been removed, and the support system lengthened. The crashpad has been extended to full length, and therefore offers a smoother and softer ride than ever before.
The Brooks Adrenaline GTS 14 was an anomaly in the history of the GTS, being less stable than runners had grown to expect from the series. However, the new Adrenaline GTS 15 ups the support, and adds in more flexibility, and a harder wearing, more stable mesh, making it more akin to the GTS 12 and 13; two of the best GTS's to date. We give it a 9 out of 10
