2. Air Jordan IV "UNDFTD"

Originally released: 2005

We don't normally rank non-original Air Jordans this high, but non-original Air Jordans aren't normally this good. Our pick for the best sneaker of the 2000s, the UNDFTD Air Jordan IV took inspiration from the MA-1 flight jacket and gave an all-time classic a refreshing tweak. They were nearly impossible to get when they dropped — only 72 pairs were made available, by raffle only — and are essentially completely impossible to get now. Good luck.
