The old Kobe vs LeBron rivalry heats up once again, this time without the puppets, as the prominent pair each drop a new Air Force 1 silhouette. The serpentine Black Mambas seen earlier in the week will face off against these colossal King James joints, with the monochrome mammoths dressed up in black leather on a crispy white sole. Both pairs are available now at Rock City Kicks. Extra pics via Sneakernews.
