The adidas 4D Fusio 'Grey Solar Yellow' boasts a striking gradient appearance on its 3D-printed midsole, which remains partially hidden beneath a durable TPU wrap. This exceptional midsole is the result of a groundbreaking manufacturing method that combines light, oxygen, and liquid resin. Supporting the midsole is a lattice structure, while the upper of the sneaker is skillfully constructed from breathable Primeknit material in a sleek monochromatic grey hue. Adding to its futuristic appeal is the form-fitting, sock-like design that features an integrated lacing system, complete with translucent tubing for a truly cutting-edge look.
