Its "Maebongsan"-trademarked shoes took the first place at the 2018 National Footwear Exhibition.

The factory is now pushing ahead with the work to produce various kinds and styles of varicolored and light shoes.

It developed a device for measuring foot size and established a process of producing light soles based on supercritical carbonic acid gas. It also introduced a compressor into the work for making the outer rim of shoes to improve quality and speed and save much manpower and materials in the cutting process.

By using quality coloring agent with shiny and adhesive character and infrared lamp in drying process, the factory lowers production cost and raises adhesive strength.

When visiting the factory in December last year, Supreme Leader Kim Jong Un expressed satisfaction over the successes made by its employees.
