We are very proud to present you this new project, Paradise Rubber Athletic Shoes, PRAS, which takes back the shoes made for the American army at the time. There are only two machines left in Japan today to manufacture vulcanized soles and sadly none left in the United States. They are manufactured in the same way as those produced for navy sailors in times of war. The vulcanized sole giving them extra propulsion on the slippery platforms of the ships. It is a product of very high quality and extremely comfortable.
