To tell if UGGs are real, part the wool inside the cuff: on genuine twin-face sheepskin the fleece grows straight out of the hide, with no fabric backing. Then find the security label sewn inside the left boot, with its holographic sun logos and QR code, and check the heel label and a thick, flexible sole. As of October 2026, genuine used Classic Short boots sell for roughly $40-90.
UGG boots have been counterfeited for as long as they have been popular. According to Wikipedia's account of the brand, US customs seized about 60,000 pairs of falsely marked boots in 2009 alone, and Deckers, which has owned the UGG brand since 1995, has acted against thousands of fake websites and listings. Most fakes are sold online as "factory outlet" deals. They usually fail on the material first: a polyester pile glued to fabric instead of real sheepskin. But one complication matters before you start: some genuine UGG styles are deliberately made with UGGplush, a wool-blend textile lining, rather than sheepskin. Always check what the genuine version of your exact style is made of.
Quick answer
- On Classic boots, parting the wool shows the fleece rooted in the hide. A woven or knitted fabric under the pile means it is not twin-face sheepskin.
- The security label is sewn inside the left boot. Tilt it and the sun logos shift from dark to light; the QR code should lead to UGG's own site.
- The woven heel label is neat and evenly stitched. Since fall 2019, some genuine heel labels have no registered trademark symbol.
- Rough used values: Classic Short $40-90, Classic Ultra Mini $50-100, Tasman slipper $45-90. Classic Short retail is roughly $170-180.
How do I check if my UGGs are real, step by step?
- Part the wool at the cuff. On Classic boots, Minis and other sheepskin styles, the boot is made of twin-face sheepskin: the wool and the suede outside are one piece of hide. Push the wool apart with your fingers near the top. On a genuine boot you see the base of the fibers growing out of the skin, and the wool cannot be pulled away from the suede. On many fakes you see a woven or knitted fabric backing, or a layer of pile glued to a separate outer material. If the lining and the outside can be separated, it is not twin-face sheepskin.
- Know when a textile lining is genuine. UGG uses UGGplush, a wool-blend textile, on some styles and in some footbeds. If your style is listed by UGG with UGGplush, a textile lining is correct. If the boot is sold as a sheepskin Classic, it is not.
- Find the security label. Look inside the left boot, along the inside seam near the size tag. Genuine boots from the last decade or so carry a sewn-in security label with a reflective holographic strip. Tilt it: the sun logos should shift from dark silver to light silver. Older and newer labels differ, so compare with photos of a boot from the same season.
- Scan the QR code. Recent security labels carry a QR code that should take you to UGG's official site. A code that does not scan, or leads to an unfamiliar site with broken English, is a strong warning.
- Check the heel label. The woven UGG label on the back of the heel should be straight, evenly stitched, with clean lettering and no fraying. From fall 2019, UGG removed the registered trademark symbol from the heel label on some products, so a missing symbol alone is not a tell. Older genuine boots say "UGG Australia"; Deckers dropped "Australia" from the brand name in the mid 2010s.
- Flex the sole. Genuine soles bend easily at the forefoot and feel springy. Copies often have thin, stiff soles that barely flex. Look at the tread pattern and the molded branding on the outsole and compare them with retail photos of the same style.
- Look at the stitching. The seams on the back of the heel and the sides are neat and evenly spaced. On Classic boots the seams are exposed with a small raw edge of sheepskin, which is part of the design.
- Smell and feel. Real sheepskin has a faint, natural smell and feels dense and soft. A strong chemical or plastic smell and thin, papery suede are typical of copies.
- Check the price and seller. A Classic Short retails at roughly $170-180 depending on colorway; Extrabux reported a Zappos price of $179.95. "New" Classics at $50 from a site you have never heard of are fakes.
Classic, Mini and Tasman: what to check by style
Classic Short, Classic Mini and Classic Ultra Mini. These are twin-face sheepskin boots with the wool inside and suede outside, a woven heel label, exposed seams and a light, flexible sole. The heights differ: the Ultra Mini sits around the ankle, the Mini just above it, and the Short at mid calf. Check the wool test first, then the security label and the heel label. Platform versions have a thicker sole that should still feel light for its size.
Tasman. The Tasman is a slipper-shoe with a suede upper, a colorful braided trim around the collar, a plush lining and a lightweight molded sole. Fakes most often get the braid wrong: the colors, the pattern and its spacing should match retail photos of that exact colorway, and the braid should be stitched evenly with no gaps at the heel. Check the lining material against UGG's listing for that version, then the security label and the sole.
Tall boots and other styles. The same checks apply. On styles with a textile lining, rely on the security label, the heel label, the sole and the construction rather than the wool test.
Say you find UGGs at a thrift store
Say you find a pair of chestnut Classic Shorts in your size at a thrift store for $20. You part the wool at the cuff and see it rooted straight in the hide. Inside the left boot, a security label flashes from dark to light as you tilt it, and the QR code opens UGG's site. The heel label is neat and says UGG without "Australia", which fits a boot from the last decade. The sole flexes easily and shows moderate wear. Everything agrees. A used chestnut Classic Short with some wear sells for roughly $40-70, and up to about $90 if the suede is clean and the wool still thick. That is a good find. If the wool had peeled away from a fabric backing, you would put them back.
Genuine vs fake UGGs, check by check
| Check | Genuine UGG | Typical fake |
|---|---|---|
| Wool (sheepskin styles) | Rooted in the hide, cannot be separated | Pile on woven or knitted fabric, separates |
| Lining (UGGplush styles) | Matches UGG's listing for the style | Any textile on a boot sold as sheepskin |
| Security label | Inside left boot, sun logos shift when tilted | Missing, flat print, no shift |
| QR code | Opens UGG's official site | Does not scan, or opens another site |
| Heel label | Neat, even, straight lettering | Frayed, crooked, misspelled |
| Sole | Flexible, springy, branding matches style | Stiff, thin, generic tread |
| Smell and feel | Natural, dense, soft | Chemical smell, thin suede |
| Price new | Classic Short roughly $170-180 | A fraction of retail from an unknown site |
What are genuine UGGs worth used?
Rough resale values as of October 2026 for genuine pairs. Prices depend heavily on condition: thick wool, clean suede and little sole wear bring the top of each range. Chestnut, black and sand colors in common women's sizes sell fastest.
| Style | Retail new, roughly | Used, worn | Used, very clean or new |
|---|---|---|---|
| Classic Short | About $170-180 | Roughly $40-70 | Roughly $70-90; new in box more |
| Classic Mini | About $150-170 | Roughly $35-65 | Roughly $65-90 |
| Classic Ultra Mini | About $150-160 | Roughly $50-80 | Roughly $80-100 |
| Ultra Mini Platform | About $160-180 | Roughly $60-90 | Roughly $90-130 |
| Tasman slipper | About $120-130 | Roughly $45-70 | Roughly $70-90 |
| Classic Tall | About $200-220 | Roughly $40-80 | Roughly $80-110 |
| Older "UGG Australia" boots | No longer sold | Roughly $20-50 | Roughly $50-80 |
Retail prices are approximate and change by season and colorway. Fakes have essentially no resale value and should not be sold as UGG.
What lowers the value of used UGGs?
| Factor | Effect |
|---|---|
| Flattened or matted wool | The biggest deduction; buyers want thick wool |
| Water stains and salt marks | Common and hard to remove fully |
| Collapsed shaft or heel | Classic boots that slouch sell for less |
| Sole wear | Worn heels cut value sharply |
| Odor | A major deduction for any worn footwear |
Common mistakes
- Calling every textile lining fake. UGGplush styles are genuine with a textile lining. Check the style first.
- Treating a missing trademark symbol as fake. It was removed from some heel labels from fall 2019.
- Calling Australian-made ugg boots fake. In Australia and New Zealand, "ugg" is a generic word for this boot style, and many local makers sell genuine sheepskin ugg boots under their own names. They are not counterfeits; they are just not the Deckers UGG brand.
- Trusting a box or a care card. Both are copied. The boot itself is the evidence.
- Washing in a machine. Heat and agitation mat the wool and shrink the suede, which cuts resale value.
How WorthPic reads UGG photos
WorthPic runs on the newest and most capable AI model available, tuned for exactly this kind of identification. From photos of the boots from the side and behind, the heel label, the security label, the sole and the parted wool at the cuff, it identifies the style, height and colorway and checks whether the label, the construction and the lining fit that style. It notes wear: matted wool, water stains, slouching and sole wear. It then gives an honest resale range with a most likely figure and names the photo that would settle a doubt, usually a close shot of the parted wool or the security label. What it cannot do is feel the suede, smell the boot or watch a hologram shift. WorthPic identifies and estimates. It does not authenticate, grade or appraise.
What to photograph
- Both boots from the side and from behind.
- The heel label straight on.
- The security label inside the left boot, sharp.
- The wool parted at the cuff, close up.
- The soles, showing tread and wear.
- Any stains or damage, honestly.
When should you get UGGs checked by someone else?
For a used pair worth $40-90, the home checks are usually enough. If you bought new boots online that fail the checks, contact UGG through its official site and report the seller to the platform you used; the security label and the wool test are the evidence they will want. A shoe repair shop that works with sheepskin can also tell you in a minute whether a boot is twin-face sheepskin.
