The Air Jordan 11 "Cool Grey 2021" marks the third release of this popular, non-original colorway for Michael Jordan's retro basketball shoe, originally introduced in 2001. The "Cool Grey" color scheme of the Air Jordan 11 is renowned for its significance and impact, even though it's not one of the original color options for this silhouette. It made its debut in March 2001 and was notably worn by Michael Jordan during his time with the Washington Wizards. The success of the "Cool Grey" design led to its adaptation on other Air Jordan models like the Air Jordan 3, Air Jordan 4, and Air Jordan 9.
This colorway was reintroduced in December 2010 and later in December 2021, commemorating the 20th anniversary of the shoe's original release. Notable features include a Cool Grey patent leather mudguard, a Medium Grey synthetic nubuck upper, and a white embroidered Jumpman logo on the collar. The design is complemented by white "23" detailing on the heel, white laces, and a white foam midsole. The shoe's iconic appearance is rounded off with an icy translucent blue outsole. The release date for this version was December 11, 2021.
