The Air Jordan 21 (XX1 or XXI) Low - White / University Blue - Metallic Silver were released on July 12, 2006, and retailed for $135. They feature an all white leather upper with light blue accents. One of the most noticeable features cents constructed from mesh, which provide plenty of ventilation for the bearer's foot. They also feature a double-overlasted phylon midsole supporting four I.P.S.(Independent Podular Suspension) pods on the outsole.? There is a carbon fibre shank plate in the midsole, as well as an improved I.P.S. technology with interchangeable heel Zoom air pillars or encapsulated air pillars. It is not recommended that you play basketball in these, as they do not provide enough support around the ankle, and can cause severe ankle sprains.
