adidas 4DFWD shoes redefine forward motion. The cutting-edge design features a 3D-printed midsole that compresses with each step to transform energy from the impact into forward motion. In other words, every stride helps propel you to the next to turn up your pace with every step. 4DFWD running shoes offer smooth transitions and a unique gliding experience and help to energize every stride. Add the foot-hugging support of the adidas PRIMEKNIT upper, and you have the support and comfort you need to focus on your training goals.
