NIKE's check mark is said to be the check mark given by the judges during a sports shoe evaluation in the United States as its own LOGO.

Guirenniao’s LOGO was designed with reference to NIKE, with the check mark turned upside down and a little bit added. Guirenniao started out as a counterfeit, then endorsed by celebrities, and then applied for a famous brand trademark. Generally speaking, the trademark recognition is far worse than Nike, and the quality and price of the shoes are not bad.
