Can someone explain the deadstock meaning? Is it just old inventory? or What exactly is the deadstock

Wow, thanks everyone! This totally clears up the deadstock meaning for me. Didn’t realize it was such a big deal in sustainability too.

Gonna check out some of those sites you mentioned—already found a few cool deadstock sneakers on StockX.

Quick follow-up: How do you *know* if something’s really deadstock and not just used/vintage? Are there signs to look for?

Appreciate all the help! 🙏
