Real vs Replica
Real vs Fake: How to Spot Fake Nigel Sylvester × Air Jordan 4 Retro OG SP “Brick By Brick” (HF4340-800)
Release at March 14, 2025, this Special Projects AJ4 collab between BMX legend Nigel Sylvester and Jordan Brand celebrates his NYC roots through its all-orange “firewood orange” suede design and the playful “Bike Air” heel branding. Its eye-catching build has made it highly sought-after—and, unsurprisingly, a target for counterfeits. This guide will walk you through the key differences so you can spot the real deal somehow by yourself.
How to Authenticate You AJ4 “Brick By Brick”
1. Heel Shape
Authentic: The heel is robust and well-filled, with the upper flaring outward for a solid silhouette.
Replica: The heel appears deflated and elongated, with a narrower, inward-sloping shape that lacks the authentic expansion.
2. Tongue Back
Authentic: The embroidered logo on the back of the tongue is clean and free of stray stitch marks.
Replica: Stitch errors or stray threads are visible around the embroidery, indicating weaker craftsmanship.
3. Tongue Front
Authentic: The texture of the front tongue embroidery follows the correct stitching pattern and orientation.
Replica: The weave pattern is reversed or visibly different, showing inauthentic stitching techniques.
4. Insole Back
Authentic: The inside of the insole is smooth and glossy, without any unnecessary creases or line indents.
Replica: Noticeable indentations or extraneous stitch lines mar the back surface.
5. Box Label
Authentic: The side label on the shoebox has even top and bottom margins—spacing is uniform.
Replica: The top and bottom gaps are inconsistent, with visible misalignment.
Quick Reference: “Brick By Brick” Authentication Checklist
1. Heel structure: should be full and flared outward.
