BROOKS ADRENALINE GTS 21 Black/Blackened Pearl/Nocturne
A finely calibrated mix of EVA foam, rubber, and air, DNA LOFT is the new midsole cushioning in our softest running shoe yet. Compared to the predecessor, the cushioning now extends beyond the heel, all the way to the forefoot for more stability and an even smoother transition from heel to toe.
GuideRails® Holistic Support System
We’ve shifted our focus beyond the feet to the most injury-prone part of a runner’s body: the knees. GuideRails® support keeps you moving comfortably by keeping excess movement in check. Same great shoe, NEW smoother, stable ride.
Soft, secure fit
The new Engineered Air Mesh upper hugs the foot for a secure fit while also improving breathability.
