What makes a sneaker valuable

Colourway and collaboration are the primary drivers. A Nike Air Force 1 in a standard colourway is worth retail or below. The same silhouette in a collaboration with Virgil Abloh or Travis Scott trades at multiples. The collaboration value comes from the designer's cultural credibility and the specificity of the design changes, which are usually subtle and therefore meaningful to people who know

Condition and deadstock status is the condition variable. Deadstock means unworn, in original packaging with all accessories. Wearable pairs in excellent condition trade at a discount to deadstock. Once a pair is worn, even once, it crosses into a different market

Size affects value more directly in sneakers than in almost any other collector category. The most common sizes command premiums because supply across all sizes is equal but demand is not. Original accessories matter. Box, lace bag, tissue paper, hang tags: the complete package commands a premium over the shoe alone.

CollectorGrade take

Size is a more significant value driver in sneakers than most collectors account for. A size 10 or 10.5 in a desirable colourway is worth meaningfully more than the same pair in a size 13. If you collect primarily to hold rather than wear, consider whether size optimisation is part of your strategy.
