Technical innovation is now going on at Ryuwon and Wonsan shoes factories to equip themselves with modern facilities and develop quality products.

The Phyongsong Synthetic Leather Factory has concentrated its efforts on the work to produce footwear of various kinds, styles and colors.

Similar progress is also made at other footwear factories across the country.
