The Air Jordan 19 (XIX) – Black / Chrome – Varsity Red (Countdown Package) were released alongside the Air Jordan 4 (IV) – Black / Cement Grey / Fired Red in 2008. They feature an all black upper with red accents, and are constructed from materials including leather and patent leather. They were inspired by and modeled after the most dangerous snake on earth, the Black Mamba, and truly exemplify the level of greatness that only Michael himself could attain. They feature a phylon midsole with a double stack Air Sole Unit in the heel, combined with a full length zoom air bag, as well as a 3/4 length carbon fibre shank for added support. The outsole features a solid, modified version of the herringbone pattern, which provides great traction on the hardwood, as well as new flex groove details for added flexibility. Other technical specifications include a patent leather toe box, tech-flex upper with Velcro heel strap, plastic lace-locks, Jumpman on heel and midfoot.
