Every corner of the rep world throws around terms like "1:1", "OG", and "batch" like everyone already knows what they mean. Most first-time buyers don't — and get talked into a worse pair because of it. Here's the plain-English version.
1:1 ("one-to-one")
The top quality tier. A 1:1 pair is made to match the retail shoe's proportions, materials, and construction as closely as possible — correct panel shapes, real Boost-style soles, accurate stitching. It's the tier worth paying for; anything below it is a different (and noticeably worse) product.
OG ("original")
Short for "original," referring to how closely a detail — a box, a tag, a sole texture — matches the retail version. "OG box" means the packaging matches the retail packaging. It's a quality signal, not a claim that the shoe itself is retail.
Batch
Rep factories release a shoe in numbered production runs, or "batches." Later batches usually fix problems found in earlier ones — a wrong shade, a stitching issue, a sole texture that felt off. When someone asks "what batch is this," they're asking which production run (and therefore which fixes) your pair came from.
PK (Primeknit)
Shorthand for the knit upper material used on 350 V2-style shoes. A good "PK" means the knit density, stretch, and weave pattern feel close to retail instead of stiff or loosely woven.
UA ("unauthorized authentic")
A separate manufacturing category — shoes made in the same factories as retail production, using leftover or diverted materials, without brand authorization. Not the same as a 1:1 rep, and far less common than the term gets used online.
QC (quality control) photos
Real photos of your specific pair before it ships — stitching close-ups, sole shots, tag detail — so you know what you're getting before it's in a box. Always ask for these; any seller who won't provide them is a red flag.
None of this makes a rep an original. It's still a replica — no brand affiliation, no brand warranty. These terms just describe how well the replica was made, which is what actually separates a great pair from a bad one.
