The adidas Alphaedge 4D introduced another super-clean colorway of the cutting-edge sneaker design. The crisp "Aero Green" Forgefiber textile upper is completely tonal, including the branding on the tongue and heel. The sole unit comes in the 4D's signature shade of mint green. Moving on to the star of the show, a 3D-printed midsole is built with "Digital Light Synthesis," a groundbreaking 3D printing process that uses light and oxygen. The result is an impeccable look.
