How to distinguish the authenticity of nike zoom fly3 is as follows:

A very practical and easy way to identify the Nike zoom series is to confirm the content of the shoe label, that is, to observe the corresponding relationship between the positions of letters and numbers. And the thickness of the barcode to identify the authenticity of the Nike zoom series.

The specific operation is as follows:

1. If the size under "UK" has no decimal point and is in single digits, then the extension line passes through the central axis of the number.

2. The factory code is at the upper right end of the double horizontal line, and the letters and numbers correspond to each other, such as "27.5" corresponding to "CM".

3. There are two types of barcode thickness lines. The third thickness line will not appear on genuine products.

4. The number field corresponding to the UPC barcode is still 14 digits, and the first two digits are 0. After removing the first two digits, the remaining 12 digits must correspond to the UPC serial number on the shoe box. .
