Why Gucci Slides Are Hard to Authenticate From Photos
Rubber slides and flat thong sandals look simple, and that is the problem. There is no stitching to inspect, no hardware to weigh and no interior lining. Almost everything a buyer can photograph, the web stripe, the double-G, the "GUCCI made in italy" stamp on the sole, is moulded or printed in one pass, and counterfeiters have learned to copy it well. Slides and sandals are also where our Gucci archive holds its biggest pile of counterfeits, so the question is worth getting right.
We went through a large set of genuine and counterfeit slides and sandals, checking the same model against the same model. The honest result is mixed. On the GG Blooms slide, several counterfeit pairs shared a clear tell that no genuine pair showed: the code under the strap. On the Web stripe slide, the Interlocking G rubber slide and the Marmont thong sandal, the counterfeits we reviewed were close enough that we could not publish a reliable tell, and we say so in each section rather than invent one.
What to check, ranked by reliability
| Checkpoint | Reliability | What it tells you |
|---|---|---|
| 1. The Style Number Under the Strap (GG Blooms Slides) | ★★★★★ | A code printed in ink or missing under the strap is a red flag on GG Blooms slides; a pressed code does not clear a pair on its own. |
| 2. The Sole Stamp and Tread | ★★★★★ | Counterfeit sole stamps are very close to genuine ones, so a good stamp proves little. |
| 3. Interlocking G Rubber Slides | ★★★★★ | Counterfeits copy the tread, the stamp and even the code, so this is a reference point, not a verdict. |
| 4. Marmont Thong Sandals: Bee Outsole and Hardware | ★★★★★ | Counterfeits copy the bee and both phrases; only a clearly missing or wrong bee is worth questioning. |
| Model Reference Before You Start | ★★★★★ | Makes sure you compare the right model before judging any detail. |
| What the Box and Dust Bag Do and Do Not Prove | ★★★★★ | Packaging is context only and never evidence. |

Check My Serial →Model Reference Before You Start
- Web stripe rubber slide ("Pursuit"): green and red band on black rubber, flat or lug sole. Often listed as "Web slide" or "Pursuit '72".
- GG Blooms rubber slide: GG Supreme canvas strap printed with flowers, on a black rubber base. Several colourways exist, so check the model before comparing.
- Interlocking G rubber slide: one-piece moulded rubber with the double-G in relief, in flat, platform and cut-out versions.
- Marmont thong sandal: leather thong with a gold-tone double-G plate and a leather sole carrying a bee motif.
- Slides and flat sandals carry a style number and size, not a handbag-style serial, so a Gucci serial number checker does not apply to them. The number is still useful, as the next section shows.
Do not treat "Made in Italy" as a tell on its own. Genuine pairs carry it and counterfeits copy it.
The Style Number Under the Strap (GG Blooms Slides)
Lift the strap of a GG Blooms slide and look at the underside, where it meets the footbed. On every genuine pair we checked in the pink, red and green Blooms colourway, the code reads 408508 followed by the size, and it is pressed into the rubber: tonal, the same colour as the surface, readable mostly by its relief.
Several counterfeit Blooms slides broke this pattern in the same ways. The number was printed in white or gold ink on top of the rubber, so it sits on the surface and is sharply readable. The number was often not 408508: one wrong number repeated across several different counterfeit pairs, in both the pink and the blue colourways, which is what you see when a factory prints one code on everything. And on at least one pair, the underside of the strap carried no code at all.
| Element | Authentic | Counterfeit |
|---|---|---|
| How the code is made | Pressed into the rubber, tonal | Printed in white or gold ink, or missing |
| Number (pink Blooms colourway) | 408508, then the size | A different number, often the same wrong one across pairs |
| Legibility in a photo | Low contrast, needs raking light | Crisp and high contrast |
Red flag
A style number printed in ink rather than pressed, or a strap underside with no code at all, on a GG Blooms slide. We saw this on several counterfeit pairs and on none of the genuine ones.
Worth knowing
This check is narrow. It is a strong sign on GG Blooms slides, but a counterfeit can still carry a correctly pressed code, and a genuine pair may be worn or lit so badly that the pressed code is hard to read. Style numbers also change with the colourway and season, so use the printed-versus-pressed difference first and the exact number second. On Web stripe slides the counterfeits we reviewed carried correctly pressed codes (429469 on lug-sole pairs and 308234 on flat-sole pairs, the same as genuine), so a good code there clears nothing.
The Sole Stamp and Tread
Most rubber slides carry a round "GUCCI made in italy" stamp on the sole, set in a patterned field, with a registered mark above the name. Genuine Pursuit-style slides also show concentric circles with a G in the tread.
This is a check where we have to be careful. The genuine stamps we photographed vary: some are crisp, some show "made in italy" with tight spacing, and worn pairs blur. The counterfeit stamp above is close to the genuine one. We could not find a spacing, font or layout difference that held across several counterfeit pairs and was absent on genuine ones, so we do not publish one.
Worth knowing
A sole stamp that looks right does not clear a slide. A stamp that is clearly wrong, soft, misspelled or off-centre is worth a second look, but wear and moulding differences between production years mean genuine pairs vary too. Also ignore small hand-written or circled size stickers on the outsole: we saw them on genuine and counterfeit pairs alike, because they are applied by sellers and resellers.
Interlocking G Rubber Slides
The Interlocking G slides are single moulded pieces, so the usual construction clues are missing. Genuine pairs show the double-G in relief on the strap, a tread made of repeating double-G shapes, and a "GUCCI made in italy" stamp in the tread field. The genuine pair we studied carried 692845 and the size pressed under the strap.
Counterfeit versions we reviewed reproduced the double-G tread, the stamp and, in at least one case, the same 692845 code. So the code that helps on GG Blooms slides does not separate real from fake here.
Worth knowing
We did not find a repeatable tell on this model, and we would rather say that than guess. Use the checks above as a reference for what a genuine pair looks like, and treat any mismatch you do find (a code that is printed rather than pressed, a stamp that does not match the rest of the tread) as a reason for a closer look, not a verdict.
Marmont Thong Sandals: Bee Outsole and Hardware
The Marmont thong has a gold-tone double-G plate on the leather strap and a leather sole with a small rubber insert on the forefoot. On genuine pairs the insert carries a bee, and the lettering reads L'AVEUGLE on one shoe and PAR AMOUR on the other. The footbed is stamped "GUCCI made in italy" with the size beneath.
The counterfeit Marmont thongs we reviewed copied the bee and both phrases, and the footbed stamp. Hardware looked well finished in listing photos. As with the slides, this is a case where listing photos alone rarely settle it.
Worth knowing
A missing bee, or a bee with only one phrase on both shoes, is worth questioning, since genuine pairs split the two phrases between the left and the right. A correct bee proves little.
What the Box and Dust Bag Do and Do Not Prove
Packaging is context, not evidence. Boxes and dust bags are sold separately, reused and copied. Use a box label only to cross-check the style number and size against the pair, and remember that a counterfeit pair can arrive with a correct box.
Quick Authentication Checklist
- Identify the exact model first: Web stripe, GG Blooms, Interlocking G or Marmont thong.
- On GG Blooms slides, lift the strap and read the code: pressed and tonal is right, printed in ink or missing is a red flag.
- Compare the style number with the model, but never clear a pair on a correct number alone.
- Check the sole stamp and tread for anything clearly off, without treating a good stamp as proof.
- Ignore size stickers and packaging as evidence.
- If the model is not GG Blooms, assume a good counterfeit is possible and get a second opinion before paying.
On GG Blooms slides, a printed or missing code is enough on its own to walk away. On every other model here, no single check in this guide is decisive.
When to Get a Professional Opinion
For Web stripe slides, Interlocking G slides and Marmont thongs, the counterfeits we reviewed were good enough that a buyer working from listing photos is likely to be fooled. If the price is high, or the seller cannot show the underside of the strap, the sole and the footbed in sharp light, get a second opinion. LuxeDetect authenticates Gucci footwear from $15 with a verdict and Certificate of Authenticity within 24 hours. Send the full pair, the sole close up, the footbed stamp, and the underside of the strap or the inside of the sole where the code sits.
Where This Guide Is Limited
This guide rests on a working sample of genuine and counterfeit Gucci slides and sandals from LuxeDetect's own authentication records, compared model against model. The code check is well supported on GG Blooms slides in the pink, red and green colourway. The other colourways and the other models are covered only as reference, because we could not verify a tell that held across several counterfeit pairs and was absent on genuine ones. Gucci makes many more slide and sandal styles than the four covered here.
FAQ
How can I tell if Gucci slides are real?
Identify the model, then check what that model allows. On GG Blooms slides, lift the strap and look for a style number pressed into the rubber. A number printed in white or gold ink, or no number, points to a counterfeit. For other slides, no single photo check is decisive, so combine the sole, the code and the overall finish, and get a professional opinion if the price is high.
Where is the style number on Gucci slides?
Usually on the underside of the strap, where it meets the footbed, as a six-digit number followed by the size. It is pressed in tonally, so it needs raking light to read.
Does a correct style number mean my Gucci slides are real?
No. Counterfeits copy correct numbers, particularly on Web stripe slides. The way the number is made matters more than the digits: pressed and tonal is right, printed in ink is not.
What should the sole of Gucci slides say?
Most carry a round "GUCCI made in italy" stamp with a registered mark. Counterfeit stamps can be very close, so a good stamp does not prove a pair is genuine.
Do Gucci slides have a serial number?
They carry a style number and size, not a handbag-style serial, so a serial number checker does not apply. The style number is still worth reading, as described above.
What is the bee on the sole of Gucci Marmont sandals?
It is a moulded bee on the rubber insert, with the lettering L'AVEUGLE on one shoe and PAR AMOUR on the other. Counterfeit pairs we reviewed copied it, so it is a reference point rather than proof.
Are circled size stickers on the sole a sign of a fake?
No. We saw hand-written and printed size stickers on genuine and counterfeit pairs. They come from sellers and resellers, not from Gucci.
