Ben & Jerry's Chunky Dunky Real vs Fake: How to Spot a Fake
최종 업데이트:
To tell a Chunky Dunky real vs fake, check the pair in this order: the drippy Swoosh on both sides, the tongue label and the Ben & Jerry's label inside the tongue, the size tag and the box label, the underside of the insole, the heel, the toe box and the outsole. Compare each detail with a genuine pair of the same release, because a good fake passes most checks and fails one or two.
This guide covers the Ben & Jerry's x Nike SB Dunk Low Pro QS "Chunky Dunky", style code CU3244-100. Nike SB lists the official colorway as White/Lagoon Pulse/Black/University Gold, and the box label shortens it to WHITE/UNIVERSITY GOLD. It reached select skate shops on 23 May 2020 and SNKRS on 26 May 2020 at $100. Nike describes fuzzy cow-print panels, cloud-like puffs on the heel and a drippy Swoosh, all borrowed from the Chunky Monkey ice cream pint. In the photos, the genuine pair is marked AUTHENTIC and the fake FAKE.

[ open ]The Outer Swoosh
Start with the Swoosh, the drippy yellow leather piece that is the shoe's signature. On the genuine pair, the tail of the Swoosh ends higher and runs at a straighter angle. On the fake, it ends lower and curves more. Look at the drips along its lower edge as well: their number, length and spacing should match a genuine pair, because a fake cut from a different pattern gets them wrong.
Ignore where the cow patches fall. The cow print is cut from patterned material, so the black and white patches sit in different places on every pair, genuine ones included. The same Swoosh checks work on another SB Dunk Low collab, the StrangeLove SB Dunk.
The Inner Swoosh
Now turn the shoe and check the Swoosh on the other side. On the fake we compared, it again ends lower and curves the opposite way, and it is wider than the genuine Swoosh. The drips on its right end also sit too far to the right. Both Swooshes on a genuine pair come from the same pattern, so if one side looks right and the other does not, look more closely.
The Tongue Label
The tongue label carries the Nike SB logo and "Chunky Dunky" stitched in gold. Compare three things:
- The gap under the text. On the fake, the space between "Chunky Dunky" and the stitching at the bottom of the label is larger.
- The Nike SB letters. On the genuine label they are shorter and thicker.
- The letter shapes in Chunky Dunky. Compare the curves of the C, the k and the y with a genuine label.
The fur around the label differs between pairs just as the cow patches do, so leave it out of the comparison.

The Inner Tongue Label
Inside the tongue there is a second woven label with the Ben & Jerry's logo, the motto IF IT'S NOT FUN, WHY DO IT? and MADE IN VIETNAM. On the genuine label we compared, the letters are smaller and sit evenly inside the black area, with clear space around the motto. On the fake, the lettering is larger and crowds the label. Compare the shape of the Ben & Jerry's arch and the ® beside it too.
The Size Tag
The size tag sewn inside the tongue is the busiest label on a pair of Nikes. It shows the size in several systems, the country of manufacture, the style code, a UPC barcode, a short factory code and two dates. Nike has never said what the two dates mean. They are often read as the production window, but that is not confirmed, so treat them only as a rough check that they suit the release. Tags printed from around 2019 often add a QR code, while many genuine older pairs have a barcode only. Counterfeiters copy genuine tags field by field, so a tag that agrees with itself shows the label is consistent, not that the shoes are real.
The photo below makes the point. The genuine and the fake tag both read CU3244-100, both print the dates 11/06/19 and 01/18/20, both say Made in Vietnam and both have a QR code. The fake copied every field, so a correct code and plausible dates prove nothing. Check that the tag's size and UPC match the box label, then move on to the construction checks.
On the genuine tags we have read, the later date fell two to five months before the release. A first date after the release is a question for the seller, unless the pair is a restock. Here the genuine tag's 01/18/20 sits four months before the May 2020 release. Genuine tags also print a patent line, www.nike.com/patentsvirtualmarking. A misspelt address is one of the details an authenticator compares.
What differs on the pair we compared is the print. The genuine tag's text is thinner, and the Nike Swoosh sits higher than on the fake. Tag printing changes with the printer and the factory, so compare it only with a genuine Chunky Dunky tag.

The QR Code on the Tag
The QR code on a recent Nike size tag opens an address on qr.nike.com followed by a 13-character code, and the same code is printed beside the QR. It opens a Nike page, not an authenticity check. In our November 2026 test, qr.nike.com logged each scan and sent every well-formed 13-character code, even ones we made up, to the same Nike page. Malformed codes went to the Nike home page. So a scan proves nothing either way, and fakes print working codes too. A QR that opens a site other than nike.com is a strong reason to get the pair checked, and many genuine older pairs have no QR at all. See what a Nike QR code and UPC can show.
Tested in November 2026, qr.nike.com sent every correctly formatted code, including made-up ones, to the same Nike page, with no product details and no verdict. The 13-character code uses digits and every letter except I, L, O and U, and Nike's own server rejects a code that contains one of those four letters. A clear O or U printed in the code is a strong warning sign, while a zero that looks like an O is normal.
The Box Label
The label on the end of a Nike box repeats the shoe's details: the model name, the style code, the size, the colorway and a UPC barcode, and recent labels add a QR code. On a genuine pair in its own box, the UPC on the label matches the one on the size tag, while the box QR carries a different code from the tag QR. Box colours and designs change between lines, years and collaborations, so compare only with a genuine box from the same release. A second sticker from a resale platform is normal, and so is a regional label on pairs sold in Asia. A missing or replacement box is not a sign of a fake.
A Chunky Dunky label should read NIKE SB DUNK LOW PRO QS, give the colorway as WHITE/UNIVERSITY GOLD with BLANC/OR UNIVERSITE underneath, and print CU3244 100 with the size. Both labels in our photo get these fields right. On the genuine label we compared, the text is thinner and the numbers near the QR code are slightly heavier than on the fake. Label printing varies, so use that only against a genuine Chunky Dunky label. The two labels belong to different sizes (7.5 and 9.5), so compare like with like.
The 100 in the style code is the colorway. Nike has never published the scheme, but the first digit after the dash usually follows the first colour in the colorway name, and 1 is the white family, which fits WHITE/UNIVERSITY GOLD. Exceptions exist, so a mismatch is a reason to check the code, never proof of a fake.
The tag prints the UPC as 14 digits starting 00, while the box label prints the same number as a 12-digit UPC with a small two-digit add-on. Ignore the leading zeros and the add-on when you compare them.
Codes can expose a fake but never prove a pair is real. A counterfeit label can print a real Nike barcode that belongs to another shoe or size, and a fake barcode passes the standard check digit like a genuine one. The barcode, the style code and the size must agree. To test the codes on your Chunky Dunkys, use our Nike code checker.
The Back of the Insole
Take out the insole and turn it over. The underside has a black pad in the forefoot and a cushioned area at the heel. On the fake we compared, there is extra space between the black pad and the edge of the insole, and the heel area is larger. Compare the outline of the pad and the heel area with a genuine insole of a similar size, because insoles scale with the shoe size.
The Heel
The heel is often a weak spot for fakes. Start with the NIKE embroidery on the heel tab. On the genuine pair, the gold letters are smaller and leave a clear margin inside the black tab. On the fake, they are bigger and fill the tab almost to its edges.
Below the tab, Nike describes cloud-like puffs on the heel. On the genuine pair you can see the cloud shapes quilted into the panel, with stitching lines that follow each cloud. Our fake photo shows the heel from a different angle, so compare the same view on your pair, and check that the clouds are there, evenly padded and stitched along their outlines.
The Toe Box
Look at the blue toe box from above. On the fake, the perforations are smaller and spaced further apart than on the genuine pair, which has larger holes in tighter rows. Check the stitching where the toe box meets the cow-print overlay as well: it should be even and close to the edge. Furry uppers are a common weak spot on fakes, and the Grateful Dead SB Dunk guide shows the same problem on another SB collab.
The Outsole
Finally, turn the shoe over. The green outsole has a Nike SB logo moulded into the panel in the middle. On the genuine pair the logo is smaller and centred in the panel. On the fake it is larger and fills more of it. Check the tread around the panel too, which should be crisp and evenly spaced.
Regular Box or Special Box?
The Chunky Dunky is sold in two versions under the same style code: pairs in the regular box and pairs in a "special box", packaging made to look like a Ben & Jerry's ice cream pint. Sellers list extras with the special box, such as spare laces and a tote bag. We could not confirm from Nike how many special boxes were made, who received them or exactly what came inside, so treat any seller's story about it as unproven.
The shoes are the same in both versions, so every check above applies. Packaging can be copied, or swapped from another pair, so check that its label still matches the size tag in the shoes, and judge the shoes, not the packaging. In our photos, the genuine and the fake box are both printed in the shoe's yellow, green and blue, which shows that box design alone cannot settle anything.
Frequently Asked Questions
How can you tell if Chunky Dunkys are fake?
Compare the pair with a genuine CU3244-100: the end point and drips of both Swooshes, the tongue label, the Ben & Jerry's label inside the tongue, the size tag and box label, the insole underside, the heel tab and clouds, the toe box perforations and the outsole logo. A genuine pair passes every check. One correct detail proves nothing on its own.
Did the Chunky Dunky come in a special box?
Some pairs did. A "special box" version packaged to look like a Ben & Jerry's pint is sold separately from pairs in the regular box. The shoe and the style code are the same (see Regular Box or Special Box?).
Does the style code on the size tag prove a Chunky Dunky is real?
No. The fake in our photo prints the same CU3244-100, the same dates and a QR code. The code tells you only which shoe the label claims to be. The Swoosh, labels, heel and sole decide.
When did the Chunky Dunky release and what did it cost?
Nike SB released it in select skate shops on 23 May 2020 and on SNKRS on 26 May 2020, at $100.
Why is the cow print different on my pair?
Because it differs on every pair. The patches fall wherever the material was cut, so placement is not a tell. Compare the Swoosh, the labels and the stitching instead.
See If Your Chunky Dunkys Are Authentic
If you are still unsure after these checks, send clear photos of both shoes from both sides and from behind, the tongue label, the label inside the tongue, the size tags, the insoles from both sides, the outsoles and the box label. LegitGrails authenticates Nike from photos you upload, with results in under 30 minutes and a digital certificate with every order.
