The early '00s were a weird time for performance basketball sneakers - Mike was retired (again) and LeBron James was still whiling away the time in high school. Meanwhile, Allen Iverson's signature line was sort of all over the place, going from the Hexalite-cushioned Question to the all-new DMX-infused Answer. The ultimate Iverson shoe, it seemed, would simply emphasize his greatest trait - quickness. The Answer IV did exactly that, in a way that no Iverson shoe before or since could match. The zip-up shroud provided its streamlined design, and the whole look was based around motion and speed. A historic shoe.
