Zori
Zori (草履) are sandals made from rice straw or lacquered wood and are worn with a kimono for formal occasions. A traditional Japanese footwear is not seen that often these days, as it is usually only worn with other traditional clothing, their design is quite similar to "flip-flops".
Like all Japanese sandals, Zori allow for free circulation of air around the feet, a feature that probably came about because of Japan's humid climate.
