How We Authenticate
Every Pair

Fakes never make it on. Here's the exact in-hand process every consigned pair goes through before it lists — box to smell test.

Why authentication is the whole business

A consignment shop runs on one thing: buyer trust. Nobody consigns their grails to a platform buyers don't believe in, and nobody pays resale prices for a pair they're not sure is real. So authentication isn't a step in our process — it is the process. Every pair we list is authenticated in hand by our team, physically, at our California receiving point. No photo-only approvals. No exceptions.

The sneaker market is also where the fakes are best. Modern replicas get the silhouette right, the colors right, and even most of the details right. Catching them takes hands on the pair: feeling the leather, flexing the midsole, smelling the glue. Here's how we do it, layer by layer.

Layer 1 — The box and the label

We start before we ever touch the shoes. The box tells a story, and counterfeiters almost always tell it wrong somewhere. We check the box's construction and print quality, then go deep on the size label: the typography, the spacing, the alignment of the size run, the factory code, and the placement of every line. Retail boxes are produced to tight, consistent standards — the label layout for a given model and release barely varies. A font that's slightly too bold, a barcode that's slightly too short, or a manufacturing date that doesn't match the release window is enough to fail a pair on the spot.

We also check that the box actually belongs to the pair inside: model name, colorway code, and size have to line up. A real pair in the wrong box is a listing problem and a trust problem, so mismatches get flagged.

Layer 2 — SKU verification

Every legitimate release carries a style code — the SKU — printed on the box label and on the size tag inside the shoe. We verify that the SKU on the box, the SKU on the interior tag, and the actual colorway of the pair all match each other and correspond to a real retail release. We cross-check the manufacturing date and factory code against what's known for that release. A pair can look perfect and still fail here if the paperwork inside it belongs to a different shoe.

Layer 3 — Materials and construction

This is where in-hand inspection earns its keep. Photos flatten leather into pixels; hands feel the difference between full-grain leather and corrected grain, between real suede and a synthetic nap, between a mesh that breathes and one that just looks like it does. We check the weight and hand-feel of every panel, the quality of the glue work along the midsole, the density of the foam, and the finish of overlays and eyelets.

We also check construction details counterfeiters consistently get wrong: the shape of the toe box, the stiffness of the heel counter, the pattern of the outsole tread, the way the tongue is padded and stitched. Factories making the real thing use specific lasts, molds, and materials — replicas approximate them, and the approximation shows up in the details.

Layer 4 — Stitching and details

Retail pairs come off production lines with remarkably consistent stitching: even spacing, straight lines, clean backstitching at stress points. We examine the stitch count and alignment on every visible seam, the embroidery quality on logos and heel branding, the printing on insoles, and the molding on lace aglets and lace locks. One crooked swoosh panel, one blurry size print, one insole logo that sits a millimeter off — any of these can be the tell that ends a pair's journey.

We pay special attention to the details that fakes treat as decoration: the exact shade of a secondary color, the texture of a patent overlay, the perforation pattern on a toe box. The real factories sweat these; the fake ones photograph them.

Layer 5 — The smell test

Yes, we smell the shoes. Factory-fresh sneakers carry a distinct chemical signature from the glues, dyes, and materials used in legitimate production — and replicas, made with different adhesives and cheaper compounds, smell noticeably different. It's the oldest trick in authentication and still one of the most reliable. Combined with the other four layers, it closes the loop: a pair has to look right, feel right, match its paperwork, and smell right.

What happens when a pair fails

It doesn't list — it's that simple. We document the specific failure, because "failed authentication" without a reason helps nobody, and we return the pair to you at your expense. No listing fee is ever charged on a pair that fails; we don't make money on rejections.

We take failures seriously but not personally. Sometimes it's a fake; sometimes it's a genuine pair with a replaced insole or a box swap that we can't verify with confidence. Either way, our rule is the same: when in doubt, it doesn't list. That strictness is exactly what makes the pairs that do list worth more — buyers know every listing survived this process.

The bottom line: five layers, one pair of hands, zero shortcuts. Box and label, SKU verification, materials and construction, stitching and details, and the smell test. Pass all five and your pair lists with our full backing. Fail any one of them and it goes home.

Why we publish our process

Most platforms treat authentication as a trade secret. We see it differently: telling you exactly how we check builds more trust than keeping it vague. Buyers who understand the process bid with confidence. Consignors who understand it send us better pairs and price them smarter. Transparency is the whole point of consignment — you trust us with your sneakers, so we show you our work.

Authentication FAQ

Do you check every pair for fakes?

Yes. Every consigned pair is authenticated in hand by our team before it lists. We inspect the box labels, verify the SKU, check materials and construction, examine the stitching, and run a smell test. Pairs that fail any part of the process don’t list.

What checks are in your authentication process?

Five layers: box and label inspection (typography, placement, barcode), SKU verification against the pair and box, materials and construction assessment (leather, suede, mesh, glue work), stitching and detail examination, and the smell test for factory chemical signatures.

Why do you authenticate in hand instead of from photos?

Photos flatten everything that matters: the weight of the leather, the texture of the grain, the stiffness of the toe box, the smell of the glue. Holding the pair is the only way to check all of that, so every consigned pair is inspected physically at our California receiving point before it lists.

What happens if my pair fails authentication?

It doesn’t list — it’s that simple. We document the specific failure and return the pair to you at your expense. No listing fee is ever charged on a pair that fails.

Do used sneakers go through the same authentication?

Yes. New and used-like-new pairs go through the same in-hand process. With used pairs we also verify that condition matches what you told us on the intake form — honesty upfront keeps the whole process moving.
