Yes Korean shoes are strictly appraised. Nike's sports shoes manufacturing plants in China are mainly concentrated in South China and the southeast coastal areas. Since the early Nike factories were located in Taiwan Province Province and South Korea, and the labor costs in Taiwan Province Province and South Korea rose, Nike factories moved from Taiwan Province Province and South Korea to Chinese mainland after 1980s. The most representative enterprises are Fengtai Group of Taiwan Province Province, Baocheng Group of Taiwan Province Province and Guang Tai Group of Korea. These three companies have produced about 90% of Nike products in the world so far.
