Retro, which means reproduction, refers to the re-release of a sneaker model that was previously released. Typically, after a few years, original colorways are re-launched. OG is short for Original, representing the original version or the reissued version of the original colorway. The original colorway is often considered the most classic and orthodox combination for a shoe model. Many popular AJ models periodically release new colorway reissues, but the original colorway is often reissued only once every few years and in very limited quantities. As a result, original colorways are usually highly valued and cherished by collectors.
