Per Nike: Nike pays tribute to the process that forms iron with the LeBron 11 ’Forging Iron’ colorway. Its unique blend of colors is taken from the molten metal’s metamorphosis. The fiery shades of orange represent the iron when the metal is at its most malleable—fresh from the furnace. A subtle fade effect represents sparks, while a metallic green hit on the Swoosh represents the transitional, temporary part of the process—cooling to a new shade and finished with an ice outsole.
