The 2021 Air Jordan 11 Retro Cool Grey (GS) features a grey nubuck upper with a patent leather mudguard, paying homage to the original 2001 design. The shoe includes a textile heel tab with a stylized '23' and a white Jumpman logo on the lateral ankle. The Phylon midsole offers lightweight cushioning, with an Air-sole unit for comfort, all supported by a translucent rubber outsole. This grade school sizing release celebrates the 20th anniversary of the iconic colorway.
