Rain or shine, road or trail, feel the rush with the Brooks Adrenaline ASR 12 and take on every season.  Supportive medial posting in an adaptive BioMoGo DNA midsole keeps your stride steady, and a rugged outsole is fine tuned for a smooth ride over a variety of terrain.  A breathable mesh upper repels water to keep your feet dry and comfortable in wet weather conditions.


Features:

• BioMoGo DNA fuses BioMoGo midsole and DNA cushioning technology for a fully custom responsive ride that adapts to the needs of each and every runner.
• Progressive Diagonal Rollbar (PDRB) begins at the medial heel and extends through to the medial forefoot. PDRB is a tri-density BioMoGo construction which is designed to smoothly reduce excess pronation.

• DRB Accel is a thermoplastic polyurethane unit located in the midfoot for balanced support and torsional rigidity.
• Omega Flex Grooves enhance midsole flexibility without compromising cushioning.
• Flextra varies the degree of support providing tuned flexibility.
