The short answerStart with the labels: the size tag, style code and country of manufacture should make sense for the exact model and agree with the box and any paperwork. Then compare construction, stitching, materials and packaging with a known genuine pair of the same release. For higher-value items, use a professional authentication service.
What to check
Labels and size tags
- What it is
- The tag inside the tongue or collar (sneakers) or the neck and care labels (clothing).
- How to check
- Read every line. Printing should be crisp and consistent, with no obvious spelling errors.
- Why it matters
- Labels identify the exact product and are one of the first places inconsistencies show up.
- What to photograph
- Every label, in focus.
- When to get help
- Blurry, misspelled or mismatched labels.
Style / SKU code
- What it is
- A product code that identifies the model and colorway.
- How to check
- Look the code up and check it matches the model and colors in front of you. Compare it with the code on the box label.
- Why it matters
- A code that belongs to a different shoe or color is a strong reason to stop and look closer.
- What to photograph
- The tag and the box label.
- When to get help
- Codes that do not match the shoe or each other.
Stitching and construction
- What it is
- Seam placement, stitch density, panel shapes and symmetry between the left and right shoe.
- How to check
- Compare side by side with photos of a confirmed genuine pair of the same release.
- Why it matters
- Construction details are hard to copy exactly.
- What to photograph
- Both shoes from the side, heel and toe.
- When to get help
- Uneven stitching, sloppy glue, mismatched shapes.
Materials
- What it is
- Leather, suede, knit, rubber and hardware.
- How to check
- Feel and smell. Genuine materials usually match the product description; compare with a known genuine example.
- Why it matters
- Materials are a common cost-cutting point for copies.
- What to photograph
- Close-ups of the materials in daylight.
- When to get help
- Materials that do not match the model description.
Packaging and accessories
- What it is
- Box, box label, lid, tissue, extra laces, hang tags.
- How to check
- The box label should describe the same size, model and colorway as the shoes.
- Why it matters
- Mismatched boxes are common - sometimes innocent, sometimes not.
- What to photograph
- The box label and all accessories.
- When to get help
- A box label for a different product.
Product-code consistency
- What it is
- Whether every identifier - tags, box, receipts - tells the same story.
- How to check
- Line them up and compare.
- Why it matters
- Consistency is reassuring; inconsistency is a reason to dig deeper, not automatic proof of a fake.
- What to photograph
- All identifiers together.
- When to get help
- Several details that disagree.
When does professional authentication make sense?
When a pair or garment is valuable, heavily counterfeited, or something about it does not add up. Photo-based services are inexpensive compared with the cost of a mistake.

Common mistakes

- Skipping the soles and insolesConstruction details there are part of the comparison.
