Nike Air Jordan XIII (13) Retro

First, make sure the shoes are manufactured with the factory codes LN3 (China) or FT1 (Taiwan) stamped on the tag. Also make sure the box has the same manufacturing country.

Make sure the style number on the box matches the one on the shoe tag.

Next, look at the hologram bubble on the side of the shoe. As you can see on the real one, it is a multi layered, 3D, hologram looking bubble. It should have "23" in the back and the jumpman in front. It should have a greenish tint to it, not orange like the fake one above.

Next, look at the bubble on the bottom of the shoe. Don't let the color distract you, different colorways have different color bubbles. What you need to look at is the jumpman. On the real one, you can see that it is inside the bubble, while the fake one looks like it is either painted on or has a decal on it.

If your shoes look painted on, they're fake.

Next, look at the leather around the hologram bubble. Notice on the real one, it is rounded and uniform around the bubble, while the fake one has a flat spot and is all over the place.

Next, look at the back of the shoe. Look at the shape of the fabric where the inner shoe comes around on the back (1). The fake one is much wider than the real one.

The fake one also has some quality issues (2). The fabric has some bulging and it looks more like flannel pillow case fabric than shoe fabric.

Here's another example of poor quality to look for.

Next, look at the carbon fiber on the bottom of the shoe. It should look waffle shaped with dots in each square. As you can see on the fake one, it has solid plastic looking pieces with dashes on it.

Here's another example of a fake carbon fiber bottom. Notice how it looks like one solid piece of plastic or maybe just a decal.
