What You’ll Love3D-Printed midsoleSock-like fit with Primeknit upperSustainably madeThe 4DFWD 2 makes forward movement feel effortless. The 3D-Printed midsole has targeted zones of support and shock absorption built in, allowing each impact to be transformed into forward momentum. The design of the 3D-Printed lattice structure shears forward on landing forces to provide softer landings and smoother transitions. By reducing braking forces involved in the gait cycle the 4DFWD redirects that energy into motion allowing for a soft impact and smooth propulsion. A soft and stretchy Primeknit upper wraps around the foot with a supportive fit and contains at least 50% recycled materials. A full rubber outsole provides traction for all conditions and has extended durability. The adidas 4DFWD 2 is an excellent running shoe created to optimize energy conservation and provide the best possible underfoot experience.
