The Shellcap Low Sneakers from PRAS (Paradise Rubber Athletic Shoes) have everything you could want from a made-in-Japan low-top sneaker. This season, the brand has adopted a reproduction of the iconic French Army M47 fabric, a heavyweight olive serge manufactured in the late 1940s. The stamp on the left foot, inspired by military contract numbers, is all hand-stamped on each pair.
The combined functions of the strong sole and upper bond, the hard to peel off sole, and the hard to lose form, are all created by the vulcanization method.
The vulcanization method is where the rubber sole and shoe body are joined together, and heat and pressure is applied in a sulfur-added kiln. At over 100 degrees Celcius for approximately one hour, pressure and heat are applied to the sneakers in the kiln. The ‘vulcanization method’ is carried out basically by hand, taking more labour and time and effort than you can imagine, so has bad production efficiency. Therefore, the number of companies using this method has decreased dramatically. Currently, it is said that including PRAS, only three companies in Japan are presently producing by the vulcanization method. They are manufactured in the same way as those provided for navy sailors in times of war. The vulcanized sole was giving them extra propulsion on the slippery platforms of the ships. It is a product of very high quality and extremely comfortable.
The factory in Kurume, which has near 150 years of history, will continue to protect the 'vulcanization method' and continue to share its good quality with the world. Each pair of these sneakers is akin to artisan ceramics.
