I bought Nike in the Fifth Ring Road of Xi 'an Bell Tower, which is a bit difficult for me to tell the truth from the false!

"The words on the insole can't be worn off" is impossible unless it is embroidered (which will make your feet uncomfortable) or printed with leather (mostly used for formal shoes).

The method of judging genuine sports shoes (personal experience);

1) Jerry-built parts are supported on the soles and sides: very thin, especially in air cushion shoes. Once you put it on, you will feel the floor when you walk two steps. It is recommended to walk on the uneven ground, especially at the junction of the carpet and the floor. The support on both sides requires you to walk in a rotating way as much as possible (like crossing when dribbling basketball). If the ankle is particularly weak, it is likely to be a fake.

2) sole printing: generally, the printing and dyeing of upper fabrics will not have too many flaws for us laymen to see, but if the soles are spliced in multiple colors, there is a great possibility of sleeve damage, which is the feeling of printing deviation.
