The following is how to identify the authenticity of newbalance725:

1. By observing the trademark of the shoes: genuine shoes have unique logos on the tongue, upper, heel, insole and other parts. By comparing these marks, authenticity can be identified.

The width of N occupies a slightly narrower 1/3 of its space, while the width of B occupies the other 1/2 of the space. Moreover, the B teeth of the genuine New Balance's NB logo are deeper, and the E font of the EU letter is somewhat different.

4. Distinguish by observing the shoe box: the genuine New Balance shoe box is more delicate in workmanship, while the fake shoe box is more rough in workmanship. There is a noticeable difference to the touch.

It is recommended to choose formal channels when purchasing New Balance to ensure the quality and authenticity of the goods.
