One of the most common signs of age on an original pair of AJ1s was a cracked and faded ankle collar. The black leather material wrapped around the ankle collars had a tendency to dry out and crack over a period of time and would often begin to flake off with wear and handling.
The ankle collars on the new Chicago mimic this weathered appearance and give a nod to collectors who understand the amount of care necessary when handling a pair of 1985 originals.
