Nike has been fined CNY4.87m (US$779,849) for selling trainers in China at a higher price and of a lower standard than in other countries, the local press reported.

The sportsear firm set the price of its Nike Zoom Hyperdunk at CNY1,299 in China -more than CNY500 higher than in other countries. The shoe was advertised as having double air cushions inside, but it was later discovered that the shoe only contained one air cushion.

A Nike spokesperson told just-style that after discovering the error, the sportswear giant took "immediate action to correct the relevant consumer product information".

The spokesperson said the company also issued a public statement in September 2011, conveying its regret for the error and apologising for any inconvenience caused to its customers.

Nike said in September 2011 it offered a full refund for unsatisfied customers and that it would cover up to CNY300 of costs relating to the product's return.

"We accept and respect how Chinese authorities have handled this issue to date and will continue to work closely with Chinese authorities to make sure all Nike products sold in China are in compliance with China's standards and regulations.

"Nike is committed to delivering high quality performance products to consumers, both in China and around the world," the spokesperson said.
