That sound you heard last Saturday morning was thousands of teens and sneaker collectors rushing past your house to get the latest holy grail of basketball shoes. Rumored to be the last official release ever, the Air Jordan XX3 ($185) is also the first environmentally sustainable shoe released under Nike's new Considered Design ethos. The XX3 features a leather and synthetic upper, quilted foams and linings with full-length Phylon midsole and Zoom Air cushioning, and a solid rubber, multi-directional outsole with a pattern inspired by Mike's thumbprint.
