The new Brooks Women's Adrenaline GTS 15 Running Shoes take equal parts support, cushion and balance, and wraps them in a stylish, high-performance package. Treat yourself to the adaptive cushioning of the BioMoGo DNA midsole that responds to your run and the full-length segmented crash pad that gives you ultra-smooth heel-to-toe transition. The Progressive Diagonal Rollbar provides reassuring stability while moisture-managing materials in the upper keep you cooler and dryer when you're on the run. The Adrenaline GTS 15 runs slightly smaller than previous models. If you are between sizes, we recommend choosing 1/2 size up.
