Heel-Tab

First difference is the heel-tab. As you can see in the highlighted green area, it’s placed a lot further away from the ankle collar on a fake Yeezy Boost sneaker.

Toe Stitching

The black stitching pattern going up the middle from the midsole is very different on real and fake Yeezy. On the retail real pair, you can see that there is a repeating clear pattern that looks like an “X” and then there is a square after it.

Insole

The writing on the insole of the real pair is black and in the opposite direction than on the unauthorized one (which is white).

Bottom of the insoles

You can spot the difference right away here. The underside of the insoles are completely different on the unauthorized Yeezy sneaker.

YZY

The ‘YZY’ is massive on the unauthorized. The font is much larger than the one on the original sneaker.

Trefoil (adidas logo)

The adidas logo is much larger on the unauthorized Yeezy sneaker.

Size Tag

Size tag on the inside says “SAMPLE” on the unauthorized Yeezy.

Footbed

Remove the insoles, then look in your sneakers. Real pair has a black strip going through the middle, while the unauthorized pair has exposed stitching.

Box

The unauthorized box is all wrong.
