How to Tell if Sneakers Are Real: Jordans, Dunks and Yeezys

Photos can show whether a pair of sneakers is consistent with the release it claims to be, and the fastest check is the size tag inside the tongue. Its style code (SKU) should match the exact model and colorway, its production dates should fit the release, and the box label should repeat the same code, size and colorway. Shape, stitching and logos add more evidence. What photos cannot do is settle authenticity: modern replicas copy tags and boxes closely, and the material, smell and inside construction only show in hand. For a final answer, a pair needs to go through StockX, GOAT, eBay's authentication program or an experienced legit check service.

It also helps to know whether the question is worth the trouble. Most worn general-release sneakers sell for roughly $30-120. The pairs that make authentication matter are hyped collaborations, original retro releases and deadstock grails, which run from several hundred to several thousand dollars.

So read the tag, compare it to the box and the release, and then decide whether the pair deserves a professional check.

Start with the size tag and SKU

Every modern Nike, Jordan and Adidas sneaker has a size tag sewn inside the tongue or on the inner side wall. It carries:

• The style code, often called the SKU. Nike codes look like 555088-101, where the first part is the model and the last three digits the colorway. Adidas codes look like CP9654.
• The size in US, UK, EU and centimeters.
• A production date range, such as 06/14/22 to 08/02/22.
• The country of manufacture, usually Vietnam, China or Indonesia.

Search the style code. It should return exactly the shoe in front of you. Some well known examples:

• 555088-101: Air Jordan 1 High OG "Chicago" (2015)
• DD1391-100: Nike Dunk Low "Panda"
• CP9654: Yeezy Boost 350 V2 "Zebra"

If the code belongs to a different colorway, or the production dates fall after the shoe was released to stores, that is a concrete inconsistency. Font, spacing and print quality on the tag also matter, though replicas copy them closely.

Match the box label

The box label should agree with the size tag on four things: style code, size, colorway name and the barcode number. A label for a size 10 in a box holding size 9 shoes is not proof of anything bad, because boxes get swapped all the time, but it lowers the value and deserves a note. A missing box lowers value on its own, often by 10-20 percent on collectible pairs.

Stitching, shape and logos

Stitching

Look at the stitching around the toe box, the swoosh and the heel. Genuine pairs are not perfect, but stitch spacing is generally even and the thread runs in clean lines. Doubled stitches, loose threads everywhere and uneven spacing around logos are worth noting.

Shape

Replicas often get the shape slightly wrong, and shape survives photos better than most details.

• Air Jordan 1: the heel, seen from behind, should curve inward at the middle in an hourglass shape. The toe box should be low and sleek, not bulky.
• Dunk Low: the toe box sits flat and the overlays follow the edges cleanly.
• Yeezy 350 V2: the stripe pattern and the heel tab line up with the knit, and the boost midsole has a consistent bead texture.

Logos

Check the Wings logo on a Jordan 1 for placement and depth of the stamp, the swoosh for its curve and where its tip ends, and the Nike Air or Jumpman on the tongue for size and position. Compare against photos of a confirmed pair of the same release, not a different colorway.

Insole

Lift the insole out if it is removable. The stitching underneath (Strobel stitching) and the print on the insole are both checked by authenticators.

What photos cannot show

• Smell. Replica factories often use glues with a strong chemical odor. A photo cannot carry it.
• Material quality. Leather softness, tumbling and suede nap are judged by hand.
• Inside construction. Glue marks, foam density and stitching inside the shoe need hands and light.
• UV checks. Authenticators use blacklight to spot stamps and guide marks invisible in daylight.
• Weight. Small differences add up, but not in a picture.

That is why a photo-based read stays at consistency. "The size tag, box label and heel shape are consistent with the 2015 Chicago release" is the strongest honest statement, and "the size tag layout does not match the 2015 release" is the strongest warning.

Who can settle it

• StockX and GOAT inspect every pair sold through their platforms before shipping it on.
• eBay's authentication program covers sneakers above a set price in many countries.
• Legit check services and apps, such as CheckCheck or Legit App, send photos to experienced reviewers for a paid opinion. They see far more pairs than any single collector.
• Experienced consignment stores inspect pairs in hand before taking them.

Deadstock versus worn

The gap between unworn and worn is bigger in sneakers than in almost any other category.

Deadstock means unworn, with the original box and its matching label. A pair that has been tried on around the house is technically no longer deadstock to many buyers. Any sole wear, creasing or a missing box ends the label.

Worn pairs are priced on condition:

• Toe box creasing and heel drag
• Sole wear and yellowing of icy or white soles
• Torn heel lining
• Scuffs, stains and paint transfer

Age alone also matters. Polyurethane midsoles in Air Max and some Jordan models from the 1980s and 1990s crumble with time, even unworn. Those pairs are display pieces, priced for collectors, not wear.

Rough values

These are typical used and deadstock prices in USD for common releases versus grails. Selling to a consignment shop or reseller usually pays 30-50 percent less after fees.

Size matters too. Very common sizes like 9-11 sell fastest, and unusual small or very large sizes can carry a premium or a discount depending on the model.

What to photograph

• The size tag inside the tongue, sharp and straight on
• The box label, same angle
• Both shoes from the side
• The heel from directly behind
• The soles
• The insole lifted out, and the stitching under it
• Close ups of the logo and any wear

Daylight works best. Flash flattens the texture of leather and suede. If you are sorting a closet full of old clothes, our guide to vintage t-shirts covers how tags date those, and the same consistency logic applies to designer bags.
