The adidas 4DFWD 'Black Solar Red' offers precision-engineered comfort within an environmentally-friendly design. This sustainable running shoe features a black Primeknit upper, crafted partially from recycled materials and devoid of any virgin polyester. Its snug fit is enhanced by a sock-like elastic collar, while the lacing system incorporates interior cables for added midfoot stability. The shoe's lightweight construction is supported by adidas' groundbreaking 3D-printed midsole, now equipped with a revolutionary bowtie-shaped FWD CELL lattice structure. This innovative sole provides a running economy similar to the popular UltraBoost midsole.
