Nike China, a leading sportswear and equipment supplier, released a statement on Thursday admitting to false advertising, Caixin.com reported.

The advertisement was for Nike Zoom Hyperdunk 2011, which has been on sale since the end of July, according to Caixin.com.

Nike said in a statement that an initial round of investigations found that the advertisement wrongfully stated that there are two Zoom Air cushions in the Nike Zoom Hyperdunk 2011 footwear.

The statement also said that customers will be refunded if they purchased the shoes with an original receipt before Sept 9, 2011.

Wang Hai, a customer and professional in cracking down on fake goods in China, recently bought a Nike Zoom Hyperdunk 2011 at a Nike store in Beijing and was the one who discovered the discrepancy.

Wang revealed that the same shoe sold in the US was made with two air cushions while in China it was only one. Nike may be accused of fraud for the false information in its Chinese advertisement.

Wang also found that the shoe sold in the US was $78 cheaper than that in China, Caixin.com reported.
