In August 2019, skate brand Alltimers collaborated with adidas to create the 'Discovery' collection, which showcased a nostalgic design of the ZX4000 sneaker. This exclusive edition shoe boasts a combination of nylon, mesh, and suede materials in a neutral color palette, paired with dual-colored Three-Stripes and a vibrant lace dubrae. The collaboration is acknowledged through a co-signed tongue tag. For enhanced stability, the sneaker features a Torsion stability bar, along with a foam midsole and rubber outsole.
