Released in December 2021, the Air Jordan 11 Retro 'Cool Grey' 2021 brings back a colorway from 2001 and 2010. Faithful to the OG, the shoe's upper is built with leather, finished in grey, and supported by a darker grey patent leather mudguard. Tonal webbing eyelets are worked into the lacing system to secure the fit, while underfoot, a contrasting white phylon midsole houses full-length Air for cushioning, with a carbon fiber plate included for added support. An icy translucent rubber outsole provides traction.
