Summarize:

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.
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.
