The adidas 4D Fusio ‘Grey Solar Yellow’ applies a gradient finish to the sneaker’s 3D-printed midsole, partially concealed by a protective TPU wrap and formed using an innovative process that blends light, oxygen and liquid resin. The lattice structure supports an upper crafted from breathable Primeknit in a monochromatic grey finish. The form-fitting, sock-like build is enhanced with an integrated lacing system that incorporates translucent tubing for a futuristic aesthetic.
