Platform boots from the 90s club and rave scene get copied more than almost any other silhouette on the resale market. Here's what separates an original mould from a knockoff before you pay for a secondhand pair in 2026.
- Checking the sole stamp and stitch line is the fastest way to spot fake platform boots secondhand.
- Original 1995-mould reissues, like SWEAR London's Air Rev Xtra Black, carry even tread depth and dense wedges.
- A listing with no close-up sole photo or size tag is a hold, not a buy, on any secondhand platform boot.
- Fresh glue lines instead of stitched construction is the single biggest tell on a fake wedge sole.
WHY THIS MATTERS
Platform boots built on archive moulds don't get restocked on a seasonal calendar. When a silhouette sells out, it's gone until the brand reissues it, and that scarcity is exactly what counterfeiters exploit on resale sites and marketplaces.
SWEAR London builds its platform boots and sneakers on original 1990s moulds, made to order, with no wholesale and no seasonal drops. That model keeps supply tight, which pushes buyers toward secondhand listings — and pushes fakes into the same listings. A boot that looks right in three photos can still be wrong in the hand.
WHAT YOU'LL NEED
- A tape measure or ruler
- Strong, direct light — daylight or a torch, not a dim lamp
- The seller's original photos, zoomed in on the sole and stitch line
- 10 to 15 minutes per pair — rushing this is how fakes slip through
- A second pair of eyes if you're unsure, ideally someone who owns the silhouette already
THE STEPS
1. CHECK THE SOLE STAMP FIRST
The sole stamp is the fastest authenticity check on any platform boot. Genuine soles carry a consistent, evenly recessed logo — no smudging, no shallow or doubled lettering. On Air Rev Xtra Black, the stamp sits flush with the tread pattern around it, not stamped on top as an afterthought. If the seller's photo shows a blurry or off-centre stamp, ask for a sharper one before you commit.
2. MEASURE THE PLATFORM HEIGHT
Wedge height is one of the easiest specs to fake badly. Ask the seller for the platform height in centimetres and compare it against the listed spec on the brand's current stock — a mismatch of more than half a centimetre on a supposedly unworn pair is a red flag, not a manufacturing quirk. Wear evens out over time, but a brand-new fake often ships with an inconsistent wedge from day one.
3. INSPECT THE STITCH LINE AROUND THE WEDGE
Original platform construction stitches the upper to the wedge along a continuous, even line. Fakes cut corners here because stitching a stacked wedge is slow and expensive — glue is faster. Look for a visible thread line running the full circumference of the sole join. Gaps, glue residue peeking through, or a stitch line that stops and restarts are signs of a shortcut build.
4. WEIGH THE BOOT IN YOUR HAND
A genuine stacked-wedge platform feels dense. The wedge core is solid, not hollow, and that shows up as real weight the moment you pick the boot up. A fake that feels suspiciously light for its size has likely hollowed out the wedge to cut material cost — hold both boots in the pair and check they weigh the same as each other, too.
5. LOOK AT THE INSOLE BRANDING
Insole printing on an original pair is sharp and doesn't rub off with a light thumb pass. Counterfeit insoles often use a cheaper print method that smudges or flakes at the edges within the first few wears. Ask the seller to press a finger on the branding and photograph it — if they hesitate, that's information too.
6. CROSS-CHECK THE SILHOUETTE AGAINST CURRENT STOCK
Before you buy, compare the listing photos against what the brand currently sells. SWEAR London's archive moulds resurface under specific names and colourways — a listing claiming a rare combination that doesn't match anything the brand has produced in 2026 or in its own archive is worth a second look. Sellers banking on buyers not checking is how most fakes move.
7. ASK FOR PROOF OF PURCHASE OR ORIGINAL PACKAGING
A genuine secondhand pair usually comes with some trace of its original sale — a receipt, an order confirmation screenshot, or the original box. It's not proof on its own, but a seller who can produce it, plus everything above checking out, is a far safer buy than one who can't produce anything at all.
TROUBLESHOOTING
The seller won't send close-up sole photos. Walk away. If a listing has been up for weeks and the seller still hasn't added a sole shot, they either don't have one that holds up or haven't thought to check — neither is a good sign.
The price is too low for a discontinued colourway. Scarcity drives up resale prices on genuinely rare platform boots. A price well below what similar sold listings fetch usually means the boots aren't what they're described as.
Listing photos look like stock images, not the seller's own boots. Reverse-image search the main photo. If it turns up on ten other listings, you're not buying from someone who has the boots in hand.
The size tag doesn't match the insole length. Manufacturers stamp size consistently across the tag and the insole. A mismatch between the two on the same shoe is a manufacturing red flag, not a quirk of an old pair.
The sole shows fresh glue lines instead of stitching. Covered in step three, but worth repeating here: a resoled or rebuilt platform boot isn't necessarily fake, but the seller should disclose it. Undisclosed resoling changes what you're paying for.

WHAT TO DO NEXT
Once you've confirmed a pair is genuine, the next question is how long it'll hold up. A stacked wedge that's been resoled once already has a different lifespan than one that hasn't — read through how to resole platform boots before you commit to a pair that's already had work done.
FAQ
How do I know if platform boots are fake before buying secondhand?
Check the sole stamp, stitch line around the wedge, and the boot's weight before you pay. Genuine stacked wedges are dense and stitched, not hollow and glued, and the sole stamp sits flush with the tread pattern.
Is a missing size tag always a sign of a fake?
Not always, but it's a reason to ask more questions. A missing or mismatched size tag combined with vague photos or a below-market price is a stronger signal than any one issue alone.
Do fake platform boots weigh less than real ones?
Often, yes. A genuine stacked wedge core is solid, and fakes frequently hollow it out to cut material cost, so a suspiciously light boot for its size is worth a second look.
Can I trust a low price on a rare platform boot colourway?
Be cautious. Scarcity pushes resale prices up on genuinely discontinued colourways, so a price well below comparable sold listings usually means the boots aren't what they're described as.
What's the best way to check a sole stamp on a secondhand listing?
Ask the seller for a well-lit, close-up photo of the sole stamp before buying. A genuine stamp is evenly recessed and flush with the surrounding tread, not smudged or stamped on top of the sole material.
Does undisclosed resoling make a platform boot fake?
No, resoling doesn't make a boot fake, but an undisclosed resole changes what you're actually paying for. Ask directly whether the sole has been repaired or replaced before you agree to buy.
Are secondhand platform boots from made-to-order brands harder to verify?
They can be, because there's no wholesale distribution to cross-check against. Brands like SWEAR London sell direct only, so comparing a listing against current site stock and photos is the most reliable check available.
ONE LAST THING
The check that catches most fakes isn't sophisticated — it's asking the seller to photograph their thumb pressed against the insole branding. Genuine printing doesn't smudge. Sellers moving fakes rarely think to test this before listing, and most won't bother doing it after you ask either. That hesitation tells you more than any spec comparison.
