The Brooks Women's Adrenaline ASR 12 GTX Trail Running Shoe is here to kill any qualms about running in less than ideal weather and trail conditions, thanks to its waterproofbreathable Gore Tex membrane. The Adrenaline ASR 12 GTX is purposely designed for the wettest, nastiest conditions you can throw its way. So go ahead, tromp through dewy forests, run through shallow standing water, and sprint down slippery switchbacks without soaking your feet or slipping out in the process. The Adrenaline ASR 12 GTX provides stability to counteract overpronation, courtesy of its Progressive Diagonal Rollbar. This tri density midsole keeps your ankle from moving inward. Combined with the shoe's Full length Segmented Crash Pad, the shoe delivers ultra smooth transitions. Furthermore, the shoe's BioMoGo DNA midsole acts like millions of flexible nanosprings for an adaptive feel to your running style, body type, and local running environment. Toss in a High Performance Rubber HPR sole with aggressive traction and Omega Flex Grooves for a go anywhere, grip anything shoe that's comfortable treading over wet, slippery trails and rugged surfaces.
