On a fake pair of Yeezys, the stitching is a messy criss-cross. The real ones have neat stitching that creates an “X” on both sides with a square separating them. Fake Yeezys could have any number of dots, but real Yeezys have exactly 9 in the center box.  The dots outside the rectangle don't count. On fake Yeezys, the stripes look like they've been printed on. A quick way to verify the shoe’s authenticity is by judging the material. A fake pair of Yeezys has a softer fabric, making it easy to identify as a counterfeit. The shoe’s tongue is another dead giveaway regarding its realness. A fake pair of Yeezy's soft material makes the tongue slouchier, while a real pair stands straight up.

Summary:
Look for messy stitching. Count the red dots on the heel tab. See how the stripes on the inside of the heel tab blend in. Check the material’s quality.
