When it comes to achieving your goals, every second counts. From training to race day, powerful performances call for high-tech gear that's optimized for speed. Introducing the latest range of lightweight running staples that help you push beyond your limits without distraction. Two adidas icons collide in the one shoe: the Ultraboost and 4D FWD. Lace in and experience a smooth, comfort-fueled ride in the Ultra 4DFWD Running Shoes — designed to move you forward. As your feet hit the earth, the high-performance midsole compresses forward, reducing braking forces and transforming the impact energy into forward motion. An adidas PRIMEKNIT upper hugs the foot with targeted areas of support.
