The adidas ZX 4000 Futurecraft 4D, originally released in 1984, combines retro aesthetics with cutting-edge technology. The 'Carbon' version, which was launched in April 2019, features a Primeknit upper with reinforced rear and forefoot panels. A synthetic heel piece provides structure to the shoe's counter. The standout feature is the 4D midsole, known for its revolutionary design that offers controlled stability and responsiveness. The midsole sits on top of a rubber outsole to provide excellent traction.
