Deadstock (often abbreviated DS) refers to items that are brand new, never worn, and ideally still in original packaging with all tags attached. The term originated in retail to describe unsold inventory that sat in stockrooms—literally 'dead' stock that wasn't moving. In streetwear and sneaker culture, deadstock status significantly affects collectibility and market value. A deadstock pair of vintage sneakers commands far higher prices than the same shoe in worn condition. The condition hierarchy typically runs: DS (deadstock), VNDS (very near deadstock—tried on once or twice), PADS (passed as deadstock—minimal wear), and various levels of 'used.' Authentication of deadstock status has become increasingly important as the resale market has grown, with platforms employing verification processes and the community developing expertise in identifying wear and aging.
