Real vs Replica

2026-03-18 09:35

The Air Jordan 4 Retro “Black Cat” (2020) (CU1110-010) reintroduced one of the most sought-after all-black Jordan 4 colorways. Originally inspired by Michael Jordan’s “Black Cat” nickname, the 2020 retro was released in January 2020 and features an entirely black nubuck upper, black midsole, and subtle graphite Jumpman branding. Because of its strong resale value and minimalist design, it has become a frequent target for replicas. Below are some reliable comparison points based on known differences.

How to Spot Fake AJ4 Black Cat 2020 Version

1. Tongue Back

Authentic: The “AIR JORDAN” embroidery on the back of the tongue is silver-grey, with tight and compact letter spacing.

Replica: The embroidery appears black, and the spacing between letters is noticeably wider.

2. Insole Top

Authentic: The Jumpman logo is white and positioned slightly lower on the insole.

Replica: The Jumpman is silver, and the logo sits too high.

3. Insole Back

Authentic: The back of the insole is blue, with thick visible glue marks and a small yellow square sticker.

Replica: The insole back is black, with no glue marks and no yellow sticker.

4. Size Tag

Authentic: The size tag shows factory code LN3, lists Made in China, and uses the QR code layout format.

Replica: The factory code appears as LN4, lists Made in Vietnam, and uses the older barcode format instead of QR layout.

5. Midsole Stitching

Authentic: The midsole interior fabric looks slightly messy, often showing black ink marks or pen markings. The circular holes are relatively large.

Replica: The interior looks overly clean, missing ink or line markings. The circular holes are smaller than the authentic one.

Quick Jordan 4 Black Cat 2020 Authentication Checklist
