Using MJ and his elite athleticism as inspiration, Tinker Hatfield returned with fellow designer Tom Luedecke to create a special Air Jordan — the AJ 2011. Singularly important to the design was the line’s first-ever interchangeable midsole. Luedecke, discussing the process once, noted the idea of selecting a weapon before battle.The revolutionary midsole in the Air Jordan 2011 allowed players to build a shoe that would complement their game. Athletes could choose between blue Zoom Air-sole unit for quickness or red Encapsulated Air cushioning for explosiveness.
