Yeezy Boost 350 V2 Synth: How To Legit Check (2025)

Last Updated on January 7, 2025 by Ch David

This guide teaches you how to spot fake Yeezy Synth.

Works for both Reflective & Non-Reflective.

Let’s get going.

How to spot fake Yeezy 350 Synth

The most effective way to spot fake Yeezy 350 Synth is by examining the size tag and the box label.

Fake size tags often display numerous inconsistencies.

1. Barcode

All authentic Yeezy 350s have unique details:

• Colorway – Synth
  • Non-Reflective: FV5578
  • Reflective: FV5666
• Style – 350 V2
• Size – From 5 to 14

You will need to look for these details to match in the scanning process.

1.1. How to scan

• Get the Legit Check App
• Open the barcode scanner
• Look up your shoebox

Then, check the results.

1.2. Authentic

• Authentic because everything checks out.
• 350 V2 Synth, FV5578, US14.

Just as on the box.

1.3. Fake

• Nothing comes up.
• That means no size, colorway, style-code, or version.

Thus, 100% fake.

The serial number is at the bottom right-hand corner of the box label.

  • US release: Serial number ends with V02 or V03.

4. Lacing

• Authentic: The lace on the side of the shoe with the stripe has to go below the other one.
• Fake: May often have the stripe’s lace above (instead of below) the other lace.

Let’s look closer:

A quick mention:

• The steps we’ve written so far are the BEST ways to authenticate this item
• The next few steps are still reliable methods…
• … but they apply to non-top-versions of replicas available for this item

If in doubt, we recommend double-checking the steps we’ve explained above this line.

5. Boost sole

5.1. Best fake

• Authentic:
  • Boost sole is slightly rigid.
  • Less differentiation between boost pellets.
  • Striped circles on the sole are well-defined.
• Fake:
  • Boost sole may not be as rigid.
  • Striped circles may not be as well-defined, and there might be more differentiation between boost pellets.

5.2. Mid fake

• Authentic:
  • Striped circles on the sole appear randomly placed, without a discernible pattern.
• Fake:
  • Striped circles on the sole follow a mathematical pattern, not appearing random.

5.3. Low fake

Above is another example of a fake.

6. Tongue

We’ll now look at the opening shape of the tongue.

• Authentic:
  • Shoe’s opening is narrower with a distinct structure, having a more pronounced upward curve at the tongue’s peak.
• Fake:
  • Shoe’s opening is wider with a different structure, exhibiting a flatter shape at the tongue’s peak.

7. Toe box

• Authentic:
  • Toe box is slender.
• Fake:
  • Toe box is significantly bulkier.

8. Stitching

• Authentic:
  • Middle stitching is wider and more structured.
• Fake:
  • Middle stitching is thinner and less structured.

9. Reflectiveness

• Authentic:
  • Laces have original 3M material that glows brightly in low light.
  • Reflective material is well-aligned, with straight and orderly lines, providing a bright and pronounced glow.
• Fake:
  • Laces may use replicated 3M material, resulting in a less bright glow in low light.
  • Reflective material distribution seems random and misaligned, lacking the distinctive glow and alignment seen on authentic pairs.

10. Insole

• Authentic:
  • The “adidas” text is thinner, with more defined characters, particularly noticeable on the letters “a” and “s”.
  • The dot above the letter “i” is well-defined, and the letter “Y” in “YEEZY” is also well-defined and appropriately thick.
• Fake:
  • The “adidas” text is thicker with less definition in the characters, most visible on letters “a” and “s”.
  • The dot of the letter “i” is less defined, and the letter “Y” in “YEEZY” appears thinner and less defined.

Shortlist: Legit check your Yeezy 350 Synth

In situations where you need to quickly authenticate your Yeezy Boost V2 Synth sneakers, consider these top 10 indicators:

1. Examine the shoe’s shape, ensuring the tongue isn’t too long.
2. Check the laces to ensure they are correctly threaded, with the right side under the right lace and the left side under the left lace when viewed from the top.
3. Inspect the size tag for any inconsistencies as described in this guide.
4. Capture a picture of the laces with the flash on to verify the 3M material’s glow on authentic versions.
5. See the box’s label for the serial number inscription.
6. Look at the toe box, as fake Yeezys often have an improperly arched and curvy shape.
7. Verify the middle stitching, as fake Yeezys may appear too thin or too thick.
8. Examine the tongue’s shape, with authentic pairs typically having a proper curve on the tongue area.
9. Analyze the boost sole, as fake pellets may not match the correct shape.
10. Inspect the insole, where fake insoles may have a rear logo that appears misshaped, with an excessively arched “R” character and improperly thick and curvy “adidas YEEZY” text. Additionally, the serial number text on the insole may be too thin.
