About Blue-dia


In 1952, the world’s first rubber thongs (FLIP FLOP SANDALS) “Beach Walk” was created by NAIGAI RUBBER INDUSTRY in Japan. It was designed by Ray Pastine, an industrial designer in the U.S., and created by NAIGAI RUBBER INDUSTRY’s state of the art, closed cell rubber sponge technology. “Blue-dia” originates from “Beach Walk”.

Japanese traditional footwear with a fabric strap (geta, zori) was generally a pair its right and left shapes were the same. On the other hand, “Beach Walk” had a shape that followed the sole-print of each side of the feet. Foot comfort was prioritised during the design process by creating tapered soles where height of the heels are set higher than the toe.

In 1953, NAIGAI RUBBER INDUSTRY started exporting “Beach Walk” to the U.S.A. “Beach Walk” created a boom in Hawaii that 100,000 pairs of them were sold in a month!!

In 1955, “Blue-dia” was created and released, which were improved and tailored for the Japanese market.

Continuous improvements have been implemented but the basic manufacturing method and design of “Blue-dia” has not been changed since it was created. “Blue-dia” is well perceived in the Japanese market as the standard rubber thongs.

Both straps and soles are made from quality virgin natural rubber. Please touch and experience Blue-dia’s remarkable durability and comfort.
