Read the row title as a sentence: silhouette + batch + (sometimes) colour or version. “AJ4 【LJR】” and “AJ4 【GX】” are different shoes in different price tiers; “NK NOCTA TECH [EU/USA Version]” is 3MadMan telling you the size block differs by market.
Codes seen in live albums on 2026-10-27
- GX
- Top-tier run in most sellers’ ladders. WWTop’s GX block (GX AF1 TS, GX AF1 2.0, GX batch O*N) and JMDY’s 【GX】AJ4 both use it as the premium line.
- KZ / KX
- High tier, frequently with a “2.0” revision suffix (JMDY 【KZ 2.0 Batch】AJ4). Revisions mean tooling changed, not that the model changed.
- LJR
- A widely quoted mid-high run across Dunk and AJ4 rows.
- VT / NEW VT
- Mid tier, common in Dunk listings (JMDY 【NEW VT】 and 【VT】 rows sit next to each other, which is a price ladder, not a duplicate).
- PK
- A budget-to-mid run that appears in both Dunk and AJ4 ladders.
- OG
- The seller’s label for the run closest to the original spec; it is a claim, not a certification.
- M / TOP / VALUE / G / BC / AY / AS / LT
- JMDY’s internal ladder labels for Dunks. They mean “this store’s tier”, so they do not transfer between sellers.
- Y3 / DT / FF / DGC / OV / TNT / RN / LW
- AJ4-specific run codes in the same album. Same principle: run identifiers, not quality grades.
- T1 / G5 / DF / HM / XP / C
- The On Cloud family ladder at JMDY, where one model may appear under four different run codes.
- b30 / LP / Summer Walk
- Koala’s naming for comparison and lifestyle lines — batch and campaign names used inside a shoe album.
- System A / Alpha SV / Beta LT / Beta AR / Gamma MX / Thorium SV
- DreamRemake’s shell-family naming, priced ¥240–¥450 in the album title. Model-name borrowing, with the price attached.
- GVC 157
- TopHotFashion’s own line label, listed alongside price-in-title rows.
The rule that matters
A batch code is only meaningful inside the store that printed it. Never assume seller A’s LJR equals seller B’s LJR; compare the QC photos and the price instead.
How tiers usually behave
| Tier label | Typical promise | What actually varies |
|---|---|---|
| OG / TOP / GX | Closest to original materials | Leather grade, sole compound, box contents |
| KZ / LJR | Strong visual match | Stitch density, insole stamp |
| VT / PK / M | Good look, cheaper build | Foam density, hardware weight |
| VALUE / budget rows | Price-driven | Print method, sizing drift |
