Prove product identity first
Model code, silhouette, colourway and size can separate a genuine opportunity from a superficially similar product.
Normalise visible condition
A clean “very good” pair and a worn pair needing restoration should not share the same expected resale value.
Use more than one market example
A range of relevant listings is more useful than one optimistic asking price.
Account for cleaning and repair inputs
Consumables, replacement laces, insoles, time and specialist work reduce the real margin.
Keep uncertainty visible
If the exact model or condition cannot be established, lower confidence and the maximum you are willing to pay.
