Every genuine pair carries a size tag inside the shoe with a SKU or style code, size, factory code, production dates, and a QR or barcode tied to that specific release. Search the style code: it should resolve to exactly that colorway, in that year. Counterfeit tags get the format close and the details wrong, a code from a different colorway, production dates outside the release window, or a QR code that scans to nothing or to the wrong product page.
That is why listings built entirely from clean side profile shots deserve suspicion. The silhouette is the easiest part to copy and the part factories copy best. The tag, the box label, and the insole print are administrative details counterfeiters handle sloppily because their buyers rarely check them. An authentication minded listing shows them unprompted.
Genuine box labels follow strict templates: font, spacing, size run, colorway name, and suggested retail information laid out the same way across a release. Fake boxes betray themselves in typeface weight, in a colorway name that is almost the official one, in size conversions that do not match the brand own chart. Compare against a verified genuine label photo, character by character if needed. This is clerical work, and it catches more fakes than squinting at toe box shape.
Shape still matters, it just ranks lower than sellers pretend. Limited releases have known profile quirks, heel height, toe spring, panel proportions, and good replicas get most of them right. Where replicas still struggle is consistency: stitching density that changes mid panel, glue marks at the midsole join, asymmetric logos between left and right shoes. Ask for both shoes, photographed separately. Pairs are harder to fake evenly than a single hero shoe.
A listing for a sold out release, in a full size run, at or below retail, weeks after launch, is making a supply claim that makes no sense. Genuine resellers hold scattered sizes bought at retail or above. Counterfeit operations hold every size because they manufacture to order. Full size runs on limited shoes are not a convenience, they are the business model showing.
Seller history sharpens the picture. Accounts whose inventory is exclusively high demand releases, with no ordinary products, no buying history visible, and prices that undercut every authenticated platform by a fixed margin, fit the replica distribution pattern. Authentication services exist on major resale platforms for a reason, and a seller steering buyers off platform to pay less is steering them away from the one check designed to catch the product.
Photograph the size tag, box label, insoles, heel, and stitching details before wearing the shoes outdoors, because worn pairs lose return leverage. Run the style code and compare the tag data with verified references for that release. If the pair fails, file with the platform with the specific mismatches itemized, not a general claim of fakeness: platforms act on documented discrepancies, and chargeback processes do too.
And be honest about the limit of photo authentication. The best current replicas pass casual inspection, which is why the channel you buy through, authenticated resale, authorized retail, a seller with verifiable purchase receipts, is the real protection. Authentication clues catch careless fakes. Provenance catches the careful ones.

Ask for a photo of the size tag inside the shoe and search its style code. The code should match that exact colorway and release year, and the production dates should fall in the genuine release window. Sellers who refuse tag photos while offering limited shoes at low prices have answered the question by refusing.
No. A QR code that scans is a start, but codes can be copied from genuine pairs. What matters is whether the code and the printed data around it, style code, factory code, dates, sizes, are consistent with that release and with the second shoe in the pair. Treat the scan as one clue among several, not a verdict.
Because their own product photographs would show the tells: tag errors, label fonts, stitching inconsistencies. Stock photos borrowed from the brand or from review sites display a genuine shoe that is not the item being shipped. A listing for an expensive limited release with no photos of the actual pair is a listing to walk away from.
For limited, sold out releases, usually yes. Genuine resale supply is fragmented: individual sellers hold the sizes they managed to buy. A single seller offering every size of a scarce shoe, especially below market price, is almost certainly sourcing manufactured replicas rather than retail pairs.
