Authentication Guide
Sneaker Counterfeits Are Extremely Common
Nike and Jordan sneakers are among the most counterfeited footwear in the world. "UA" (unauthorized authentic) fakes can be nearly identical to retail pairs. For limited releases and high-value pairs, use professional authentication services.
Critical Authentication Checks
Size tag SKU = Box label SKU
CRITICALThis is the #1 authentication check. The style code on the inside size tag MUST exactly match the style code on the box label. Any mismatch is an instant red flag.

UV light test
CRITICALUnder UV/blacklight, authentic Nike shoes show specific patterns and glue marks. Counterfeit glue often fluoresces differently.

Box Label Authentication
The box label contains critical information that must match the shoe's internal tags.
SKU/Style Code
CRITICALFormat: XXX-XXX (e.g., "DD1391-100"). First 3 digits = model family, last 3 = colorway.
✓ AUTHENTIC
Style code on box must EXACTLY match the code on the size tag inside the shoe
✗ COUNTERFEIT
Mismatched SKUs, wrong format, or missing digits
UPC Barcode
CRITICALThe barcode should scan to the correct product. Each size has a unique UPC.
✓ AUTHENTIC
Scans correctly, matches product info, proper barcode quality
✗ COUNTERFEIT
Non-scanning barcode, wrong product info, blurry printing
Box Label Print Quality
Authentic Nike labels have crisp, consistent printing with specific fonts.
✓ AUTHENTIC
Sharp text, proper Nike font, clean alignment, no smudging
✗ COUNTERFEIT
Blurry text, wrong fonts, misaligned text, ink bleeds
Production Date & Country
Box shows production country and date. Most Nikes are made in Vietnam, China, or Indonesia.
✓ AUTHENTIC
Consistent with shoe's inside tag, proper date format
✗ COUNTERFEIT
Mismatched dates, unusual production countries, incorrect formats
Size Tag Verification
The size tag inside the shoe is your primary authentication point. It should match the box exactly.
SKU must match box label
CRITICALThe style code on the size tag inside the shoe must be identical to the box label. This is the most important check.

Stitching quality
✓ AUTHENTIC
Even, consistent stitching throughout. Thread color matches design. No loose threads or skipped stitches.
✗ COUNTERFEIT
Uneven spacing, wrong thread colors, loose ends, inconsistent stitch length
💡 Pay attention to stitching around the Swoosh and tongue logos
Glue application
✓ AUTHENTIC
Clean glue lines with minimal to no visible glue. Professional factory finish.
✗ COUNTERFEIT
Excessive glue around soles, visible glue stains on upper, sloppy application
💡 Some glue visibility can occur on authentic pairs, but should be minimal
Materials and texture
✓ AUTHENTIC
Materials match the official Nike product photos. Leather should have natural grain, suede should have proper nap.
✗ COUNTERFEIT
Wrong materials, plasticky leather, incorrect textures, cheap foam
💡 Compare with official Nike product photos and verified retail photos
The Smell Test
Authentic: New authentic Nikes have a characteristic "retail smell" - a mix of glue, rubber, and materials that's distinct but not overwhelming or chemical.
Fake: Strong chemical smell, glue fumes, or unusual odors often indicate counterfeit materials and cheap adhesives.
Model-Specific Authentication
Different Nike and Jordan models have specific authentication points. Here are key checks for popular models.
- Wings logo should have correct R position and feather count
- Swoosh shape and placement varies by colorway - check references
- Hourglass shape visible from back on DS pairs
- Toe box perforation pattern should be precise
