Buying sneakers on StockX and eBay
Checklist for asks, sold comps, size, and authentication.
StockX is the authenticated ask/bid board. eBay is where sold comps and flexible condition live. Use both — and never skip the style code.
Before you buy
- +Match the style code on the tongue/box to the guide.
- +Confirm US size in the listing (or StockX size selector).
- +Compare recent solds for that size, not only the lowest ask.
- +Prefer Authenticity Guarantee / StockX / GOAT on high asks.
