The shoe also has a much more streamlined modern design, departing from the retro look of the Air Jordan 31 and 32. There are still some retro elements including the use of "Nike Air" on the heel tab, reminiscent of the Air Jordan 3, 4, 5 and 6. Fast Fit can seen on the XXXIII's outsole. It's a system made out of Ultra High Molecular Weight Polyethylene and it gets activated by a pull tab on the XXXIII's tongue. Besides now being part of the Jordan XXXIII, the cables used in Fast Fit are mostly seen in parachutes.
