deadstock
adj.— «Legions of collectors are standing, zombielike, in the wee hours outside shoe stores, waiting for them to open, mumbling words like “deadstock” and “F.O.T.B.” These people, mostly young men, are called sneakerheads. Sneakerheads want one thing: the coolest, rarest sneaker on the market, whether it be Adidas, Bape or Reebok.…(Deadstock, by the way, means a foot has never been inside the shoe. F.O.T.B. means fresh out of the box.)» —“Sole of the Sneakerhead” by Stephen A. Crockett Jr. Washington Post Apr. 21, 2005. (source: Double-Tongued Dictionary)
