What we check on Nike

How to tell a real Nike from a fake

On Nike pairs the toe box is the first tell: Dunk replicas often sit flatter at the tip and Air Force 1 copies look boxier. These are the parts of a pair our authenticators check from your photos.

01

Toe box and side profile

Toe box height and curve, Swoosh shape and placement, panel cut for the model.

02

Size tag

Style code matching the colorway, production dates, font weight and spacing.

03

Stitching

Even, secure stitching around the toe box, the Swoosh and the heel.

04

Insole and stitching under it

Logo print, then the stitching and foam color underneath.

05

Heel tab

Embroidery or print on the heel, and the heel height and shape.

06

Tongue label

Logo weave, stitching around the label and tongue padding.

07

Outsole

Pivot point, tread pattern and logo moulding.

08

Box label

Style code, colorway name and size matching the size tag.

Featured questions

Have more questions? Visit our Help Center

How do I check if my Nike Dunks are real?

Photograph the side profile, the toe box, the size tag inside, the insole and the stitching under it, the heel, the outsole and the box label. On Dunks the toe box curve and the size tag print are often the first giveaways. Our free Dunk guides show what each detail should look like.

Is there an official Nike QR code or serial number check?

Not one that proves a pair is real. The style code on the size tag and the box names the model and colorway, and any code or QR code on a label can be copied from a genuine pair. It is one checkpoint, so we check the code against the pair and then the pair itself.

How can I tell if Air Force 1s are fake?

Look at the toe box first. On a genuine white Air Force 1 it is slimmer, while many copies look boxier, with outlines that are too thick and dark and a dot pattern that does not match. Then check the stitching, the heel counter and the sole.

Can you check Nikes I bought on StockX, GOAT or eBay?

Yes. A platform tag or verification slip is one checkpoint and can be copied or moved to another pair, so we judge the shoes themselves. Send the same photos as for any pair, and do it soon after delivery so you know where you stand.

Are Nikes made in Vietnam fake?

No. Nike says most of its footwear is made in Vietnam, Indonesia and China, with Vietnam the largest. The country on the size tag only matters when it does not fit what that model and release used.

Can you check Nike clothing too?

Yes. Tech Fleece and other Nike clothing are authenticated on this page from photos of the labels, the wash tags and the construction, compared with verified references for that piece and season.

Which photos should I upload for authentication?

For the most accurate and quick authentication process, we advise you to upload clear photos of the areas visible when clicking 'Upload photos' on this page. We quickly determine if the uploaded photo meets our criteria. If your photos do not meet the criteria, you will receive a request for more and/or clearer photos. Check out Photo Instructions to find clear examples for each detail.

How long does LegitGrails authentication process take?

We provide a range of authentication response times to suit your needs, with options including 12 hours, 6 hours, 2 hours, and 30 minutes.
