The Air Jordan 13 (XIII) Retro - Countdown Package 10 / 13 (White / Black - True Red) were released in 2008 as part of the very first Air Jordan Countdown Package. They were released together alongside the Air Jordan 10 (X) Retro - Shadow Grey (Countdown Package 10 / 13), and feature the already retroed white / black - true red color scheme, which is one of the most popular among fanatics. They feature a leather construction and are modeled after the paw of a black panther. The green hologram at the heel is said to be the eye of the beast, while the white area along the midsole represents the paw. The outsole features a modified herringbone pattern which provides great traction, and along with the Zoom Air insoles, help to make these very comfortable shoes.
