When Michael Lau was commissioned by Nike to design a pair of Air Force 1s as apart of the Nike1World campaign, he came up with a model he nicknamed “Crazy“, getting its inspiration from mental asylums. This unique concept has a few components that tie into the “Crazy” theme including the quilted pattern that makes up the upper along with tally marks at the heel of the sneaker. Other markings have been added to the tongue and on the inside of the sneaker. Kix-Files has one size available for $680.
