What your sneaker collection is actually worth
"Worth" isn't a feeling — it's a number you should be able to defend. Here's what goes into ours.
Ask ten collectors what their rack is worth and you'll get ten different methods — a gut estimate, whatever a marketplace's homepage happens to show for one pair, an average of what people are asking rather than what anyone actually paid. None of those hold up if someone asks "how do you know?"
CYKI builds a pair's value from real, completed sales in your exact size — specifically the median of the last several sales, not just the most recent one, because a single sale can be an outlier. If your size hasn't traded recently, the estimate widens to a neighboring size before it ever falls back to what's merely being asked. Even an old sale still counts — CYKI shows you its date so you can judge how current the number is. Only a shoe with no recorded sale anywhere, ever, gets nothing invented: "no sales on record," not a number nobody's paid.
That's the difference between a number and an estimate you can stand behind: every figure in CYKI traces back to something that actually happened in the market, and the app doesn't hide which fallback it used to get there.
Condition plays into it too. Grade a pair honestly and the estimate adjusts down from what a pristine version of the same shoe would fetch, because a worn shoe doesn't sell for the deadstock price — leave it ungraded and CYKI treats it as deadstock by default, no reduction applied.
