UNheardof and Anonymous teamed up with Nike SB for a December 2015 Dunk SB two-pack inspired by the Cincinnati Reds’ win against the Oakland A’s in the 1990 World Series. This Dunk High Pro SB ‘Oakland Athletics’ features a Stadium Green and Speed Yellow suede upper with a white mesh tongue and a perforated leather toe box. It also comes with an embroidered US flag patch on the lateral heel. Shortly after the initial drop at UNheardof and Anonymous . the MLB sent a cease-and-desist letter that prevented a wider release at select Nike SB accounts.
