This black/chrome colorway serves as a tribute to the “Rubber City”, a nickname held by the city of Akron, the rubber capital of the world during the 20th century. This pair of LeBron 12s captures that aura with a sick rubber tiled upper as well as the “330” area code on the heel-tab. The Chrome Swoosh adds some flair to this otherwise stoic concept.
