Another sample recently showed up on our sneaker marketplaceĀ is from the Be True Chronicals, the Alphanumeric Pro B was one of the Dunks that set the precedence for then newly enginereed Nike SB Dunk Low, rumored to be around 36 pairs available in the world these were given to friends and family and are considered a grail amongst collectors and older skateboarders alike as a defining moment as the second Dunk collab in Nike's history.
