The Shellcap Low Sneakers by PRAS (Paradise Rubber Athletic Shoes) offer all the desirable features of a Japanese-made low-top sneaker. They showcase a distinctive bulbous shellcap toe box and non-slip soles inspired by 1950s athletic footwear. The unique kiln-fired vulcanization process, exclusive to Kurume, Japan, adds to their appeal. Furthermore, the red stitching and vintage-inspired heel panel add a final touch of color.

The vulcanization technique employed in the manufacturing process ensures a robust bond between the sole and upper, a sole that resists peeling, and a shape that maintains its integrity. This process involves the fusion of the rubber sole and shoe body using heat and pressure in a sulfur-enhanced kiln. The sneakers endure over 100 degrees Celsius of heat and pressure for approximately one hour during vulcanization. This method primarily relies on manual craftsmanship, demanding a substantial amount of labor, time, and effort, which results in lower production efficiency. Consequently, the number of companies employing this method has significantly dwindled. Currently, only three companies in Japan, including PRAS, produce sneakers utilizing the vulcanization method. These sneakers are crafted in the same manner as those supplied to naval personnel during wartime, as the vulcanized sole provided them with enhanced traction on slippery ship decks. They are renowned for their outstanding quality and ultimate comfort.

The Kurume factory, boasting nearly 150 years of history, is dedicated to preserving the vulcanization method and sharing its exceptional quality with the world. Each pair of these sneakers is akin to artisan ceramics.
