The original 550 debuted in 1989 and made its mark on basketball courts from coast to coast. After its initial run, the 550 was filed away in the archives, before being reintroduced in limited-edition releases in late 2020, and returned to the full-time lineup in 2021, quickly becoming a global fashion favorite. The 550’s low top, streamlined silhouette offers a clean take on the heavy-duty designs of the late ‘80s, while the dependable leather, synthetic, and mesh upper construction is a classic look in any era.
