These running shoes are built to keep you moving forward. whether you're new to running or have finished so many races you've lost count. The lattice design of the 3D-printed 4D midsole compresses with each step. reducing braking forces and transforming the impact energy into forward motion. The result? Smooth transitions and a unique gliding experience. The adidas PRIMEKNIT upper hugs the foot with a flexible fit that enhances movement.
