A lot of things in the vid are true but also sometimes a bit too general, as they can be different even for different cws of the same model.
I bought AMPs from FL EU a month ago.
No nikebetterworld on the size tag.
No nikebetterworld on the box label.
Layout of box label exactly the same.
Layout of the size tag exactly the same, only difference is the tag on this pair is pressed a bit further into the fabric.
And I don't see anything else on the shoe that worries me.
