First to the tackle. First to the ball. First to the try line. When speed is your game, these adidas Adizero RS7 rugby boots keep you way out ahead. Geofit technology in the heel of the lightweight synthetic upper fills every gap with foam Sensepods, keeping your feet strapped in for sidesteps and sprints. Underneath, a lightweight firm ground outsole digs in for lightning acceleration. This product is made with Primegreen, a series of high-performance recycled materials. 50% of the upper is recycled content. No virgin polyester.
