The 4DFWD 2 running sneakers by adidas redefine forward motion combining the unique, groundbreaking innovation of a 3D printed midsole with new upper construction and a Continental outsole for extra grip. The midsole compresses forward, reducing braking forces and transforming the impact energy into forwarding motion while the continental outsole grippy rubber outsole provides traction on wet and dry surfaces to keep you going in all conditions. Made with a series of recycled materials, this upper features at least 50% recycled content. This product represents just one of adidas' solutions to help end plastic waste.
