First released in 1997, the Air Jordan XIII is a Tinker Hatfield-designed model that was inspired by the black panther. Hatfield used the quick and elusive animal as inspiration because it mimicked Jordan's playing style. Jordan strived to come out of nowhere on the court, possess a ferocious edge, and be there and gone before opponents could react. Available in several colorways, the Air Jordan XII "Grey Toe" was an unreleased sample that first went into production in 2005. The "Grey Toe" model features two of the most recognizable elements of the AJXIII design, including an outsole that represents paw prints, and a hologram that resembles a panther's eye. It has been nearly 10 years since this retro model was released, so it will likely be another highly sought-after Air Jordan model.
