The Air Jordan 21 Retro 'Countdown Pack' is an homage to the classic "Bred" (Black and Red) color scheme, and was released as one half of a two-shoe package with the Air Jordan 2. The shoe features a premium Black suede upper, giving it a luxurious feel. Varsity Red provides contrast on the midsole, heel panel, and eyelets. The shoe is known for its technical features, including a visible Independent Podular Suspension (IPS) cushioning system in the midsole, allowing the wearer to swap between Zoom Air and Encapsulated Air units (though the retro may have sealed units). Unique design elements include a diamond quilted lining and a debossed '23' on the lateral collar, drawing inspiration from high-end automobiles.
