1. Look at the shoe size.

When the number below US is a number, the number "6" is on the left side of "S". If it has a decimal point, the decimal point is on the left side of the letter "S".

2. Look at the Chinese code.

Note that the unit of Chinese code must be "cm". If "mm" appears, something is wrong.

3. The numbers under cm

If it is an integer, as shown in the figure, the first number "2" is aligned with the letter "c". If it is with a decimal point, the second number, that is, the number "3" on each position is aligned with "c".

4. Look at the place of origin.

"MADE IN INDONESIA" means that the place of origin is Indonesia. The "IM" above is the factory code. Common codes for Indonesian factories include IW, IB, IP, IM, etc. The Chinese ones include Y3, LN2, LN3, LN4, QT, etc.

5. Look at the barcode.

There are only two kinds of barcodes as shown in the picture, one thick and one thin, and there will be no third kind.
