Real vs Fake UGG Ultra Mini: How to Spot a Fake

Real vs Fake UGG Ultra Mini: How to Tell If Yours Is Real

To spot a fake UGG Mini, ignore the color and the fluff and read two things first: the sewn-in size label and the sole. In the photos in this guide, the fake UGG Ultra Mini prints its label header in a narrow, condensed type and lists the Japanese size as 250 instead of 25. Its sole lugs are straight-sided wedges with a flat outer end, where the genuine lugs are rounded teardrops.

The UGG Classic Ultra Mini (women's style 1116109) is the low-cut version of the Classic boot. UGG's 2025 product page lists it with a 3.5-inch shaft, a 17mm Twinface sheepskin upper, overlock stitching on the seams and an embossed leather heel label. The Classic Ultra Mini Platform (style 1135092) keeps the same shaft on a 2-inch platform, with a suede upper and an embossed suede heel label. In 2025 captures of ugg.com the Ultra Mini sold for $150 and the Platform for $170 in the US, and ugg.com listed the Ultra Mini at $160 in November 2026. This fake vs real UGG Ultra Mini guide covers both.

The photos come from several confirmed authentic and counterfeit pieces, not one pair, so colors and styles change from card to card. I compared six photo areas across them. Two checks held up against every genuine photo we have, and two text checks come from UGG's own pages. The checks that failed are listed near the end, because a UGG Mini fake test that also fails a real pair does more harm than no test.

How the Ultra Mini Differs From Other UGG Boots

Our general real vs fake UGG boots guide covers the brand-wide checks that apply to every Classic. This page is only about the Ultra Mini and its Platform version: the 3.5-inch shaft, the collar seam that runs right around the ankle, and two style numbers that buyers mix up. The Tasman slipper has its own braided collar and gets its own guide. If you are checking boots from another brand, our Timberland boots guide, our Crocs guide and our overview of how to tell fake vs real shoes explain the shoe checks that do not depend on sheepskin. For the Tasman slipper, see our UGG Tasman real vs fake guide.

Why the UGG Ultra Mini Is Heavily Counterfeited

The Ultra Mini went viral, and UGG itself describes the Platform as a style with "viral-status receipts". A boot that draws this much demand and costs $150 to $170 new is exactly what counterfeit factories target. The shape is simple and most buyers never look past the heel logo.

UGG has fought counterfeits for years. In a November 2015 press release, UGG owner Deckers said it had taken legal action against 60,000 websites selling fake UGG products and that law enforcement had seized more than 2.5 million counterfeit UGG products worldwide between 2007 and 2015. Those figures stop in 2015.

Footwear stays near the top of counterfeit trade in general. The EUIPO and OECD Mapping Global Trade in Fakes 2025 report estimates world trade in fakes at $467 billion in 2021, 2.3% of world trade, and lists footwear among the top categories. I compare photographs below and describe what separates these pairs, not a rule that fits every fake.

Outsole: Sunburst Lugs and Center Logo

Both soles in this photo show the sunburst tread, with 16 lugs in the inner ring and the UGG logo at the same size inside it. The difference is the outline of each lug where it meets the textured sole. On the genuine sole each inner lug is a teardrop with a round outer end. On the fake sole it is a straight-sided wedge with a flat outer end and a pointed tip.

• Outer end. Cropped to the same medallion size, the genuine lug ends in a half circle. The fake lug ends in a nearly straight edge with two corners.
• Sides and tip. The genuine lug's sides curve in toward a narrow, rounded tip. The fake lug's sides run straight to a point, like a slice of pie.
• What matches. The lug count, the logo's size relative to the ring and the overall layout are the same on both, so none of them proves anything.
• Light is not a tell. The fake sole was shot under a hard side light, so its lugs show dark walls and look flatter. Judge the outline only, not how domed or sharp a lug looks.

UGG lists two outsole compounds for both Ultra Mini styles, sugarcane EVA or Treadlite by UGG, and these two soles may not come from the same style. Compare a sole against a confirmed pair of the same style rather than against memory.

Lay the boot on its side and photograph the sole from directly above, in soft even light, so the outline of each lug is clear.

Size Label: Style Number, Font and Wording

The sewn-in label shows the clearest printing differences in this comparison. At the same letter height, the genuine header "UGG S/N" uses a regular-width type, with a G almost as wide as it is tall. The fake uses a condensed face with a G only three quarters as wide. The fake also lists the Japanese size as 250, and the genuine as 25.

• Header width. Measured at the same cap height, the genuine G is 0.97 times as wide as it is tall and the fake G 0.75. The genuine zero is 0.71 and the fake zero 0.50.
• Japanese size. For the same US 8, UK 6 and EU 39, the genuine label prints JAPAN 25 and the fake prints 250.
• French origin line. The genuine label reads "Fabriqué aux Philippines" with its accent. The fake reads "Fabrique en Vietnam", with no accent.
• The style number is not a tell here. The genuine label reads 1135092, the Ultra Mini Platform, and the fake reads 1116109, the regular Ultra Mini. Two models, two correct numbers.
• One caveat. Our genuine label belongs to a Platform made in the Philippines, while the fake claims a regular Ultra Mini made in Vietnam. I have not found a published photo of a confirmed Vietnam-made Ultra Mini label, so compare yours with a confirmed label of the same style and country before calling it.
• Country is not a tell. Deckers makes its footwear through independent factories, mostly in Vietnam, and genuine UGGs also come from other countries, including the Philippines shown here.

Fold the lining back from the inside of the left boot, flatten the label with a finger and photograph it straight on so every cell is in focus.

Security Label: QR Code and Sun Logo in the Left Boot

UGG's counterfeit page, in its January 2021 archived copy, says every authentic UGG product carries a reflective security label sewn into the left shoe, a security sticker on the box, or both. Since Fall 2013 that label sits behind the sewn-in label of the left boot and carries a QR code that opens a UGG page confirming the product. That archived page names the landing page as uggaustralia.com, a domain UGG also used in its own 2015 anti-counterfeit release, so that address alone is not a warning sign. Its holographic sun logo turns from black to white when you rotate it 90 degrees.

• Where it is. Behind the sewn-in size label of the left boot, per UGG's security features page (archived copy, January 2021). The cards in this guide do not show it, and I could not confirm that the page still reads the same today, so treat it as UGG's stated system rather than something shown here.
• The sun logo. Rotate the label a quarter turn under one light. A printed sun that stays the same color does not behave the way UGG describes.
• A known exception. UGG notes that some Fall 2014 product shipped without the sun logo on the sewn-in label and tells owners to scan the QR code instead.
• What the QR proves. A code that opens anything other than a UGG domain is a red flag. A code that does open a UGG page proves less, because a printed code can be copied from a genuine label.

Film a short clip while you rotate the label under a lamp, then scan the code and screenshot the address bar of the page it opens.

Style Number vs Sole: Ultra Mini or Platform

The number after S/N on the label is the style number, and it tells you which boot you should be holding. UGG's 2025 product pages list 1116109, the women's Classic Ultra Mini, on a flat sole, and 1135092, the Classic Ultra Mini Platform, on a 2-inch platform. Both have a 3.5-inch shaft. A number that belongs to the other sole is worth a closer look.

• Number and sole height. A label reading 1116109 belongs on a flat sole. A label reading 1135092 belongs on the 2-inch platform.
• Other numbers are not automatically wrong. UGG sells other Ultra Mini versions under their own style numbers, such as the Classic Ultra Mini Leather (1157170) and the Classic Ultra Mini Bling (1119871), so a number that is neither of these two needs a lookup, not a verdict.
• Lining is not a test. UGG's 2025 Platform page lists an UGGplush lining of upcycled wool and TENCEL Lyocell, and retailer listings for the regular Ultra Mini pair its sheepskin lining with an UGGplush footbed. A wool-blend footbed, or a Platform lining that does not look like sheepskin, is normal.
• Box and label. If the box label carries a style number, it should agree with the number sewn inside the boot.

Photograph the label number next to a side view of the sole, so the number and the platform height sit in the same set of photos.

Red Flags That End the Inspection

In this fake vs real UGG Ultra Mini comparison, the size label is the finding I would stop on. A header set in a condensed type, a Japanese size printed as 250 and an unaccented French origin line are three printing differences in one small label. Check them against a confirmed label of the same style before you decide.

• A label that reads differently from a confirmed one. Condensed header type, a three-digit Japanese size or a French line without its accent puts the whole label in doubt.
• A style number that belongs to the other sole. 1135092 on a flat sole, or 1116109 on a 2-inch platform, means the label and the boot do not go together.
• A QR code that opens a non-UGG site. UGG says its code leads to its own verification page.

Not red flags on their own: suede color, the shade of the sole, how glossy the heel logo looks, the lining material, country of origin, and a correct style number. Each varies between genuine pairs or is easy to copy.

What Current Superfakes Get Right

The fake UGG Mini boots in these photos are not crude. They have the Ultra Mini's low shaft, the rear pull tab, the heel patch in the right place, a sunburst sole with the right number of lugs, a correct style number and a size grid with the right US, UK and EU sizes. Even the fake box logo matched the genuine one in its proportions, so I left the box out of the checkpoints.

Three photo checks did not hold up. The fake heel stamp's U has small spurs at the top of its stems, but so does the UGG wordmark on a genuine box, so the U shape proves nothing. Seam stitching varies between genuine pairs: one genuine collar has widely spaced stitches, another is wrapped almost as tightly as the fake's, and genuine heel seams are as lumpy as fake ones.

What these UGG Ultra Mini counterfeits still miss is tooling: the typeface and number format on the label and the outline of each sole lug. Those are set by printers and molds, and they are harder to copy than a shape.

What You Can Check Yourself and What You Cannot

The style number and the security label transfer best through a written guide, because each has a fixed answer you can check against UGG's site. Lug outline and label type are harder, because they need a confirmed pair of the same style, and for the label the same factory country, to compare against. Seams and the heel stamp vary too much between genuine pairs to judge alone.

UGG makes the Ultra Mini in many colors with two outsole compounds, so a boot that differs from the pairs shown here is not automatically fake. When we review UGG boots from customer photographs at LegitGrails, we compare each label, seam and sole against confirmed pairs of the same style.
