Geta (下駄) are a form of traditional Japanese footwear that resemble both clogs and flip-flops. They are a kind of sandal with an elevated wooden base held onto the foot with a fabric thong to keep the foot well above the ground. They are worn with traditional Japanese clothing such as kimono or yukata, but (in Japan) also with Western clothing during the summer months. Sometimes geta are worn in rain or snow to keep the feet dry, due to their extra height and impermeability compared to other footwear such as zōri. They make a similar noise to flip-flops slapping against the heel whilst walking. When worn on water or dirt, flip-flops may flip dirt or water up the back of the legs. This does not tend to happen with the heavier Japanese Geta.
There are several different styles of geta. The most familiar style in the West consists of an unfinished wooden board called a dai (台?, stand) that the foot is set upon, with a hanao (鼻緒?, cloth thong) that passes between the big toe and second toe. As geta are usually worn only with yukata or other informal Japanese clothes or Western clothes, there is no need to wear socks. Ordinary people wear at least slightly more formal zōri when wearing special toe socks called tabi. Apprentice geisha, also called "maiko", wear their special geta (see below) with tabi to accommodate the hanao.
The two supporting pieces below the base board, called ha (歯?, teeth), are also made of wood, usually very light-weight kiri (桐?, paulownia) and make a distinctive "clacking" sound while walking: karankoron (カランコロン?). This is sometimes mentioned as one of the sounds that older Japanese miss most in modern life. A traditional saying in Japanese translates as "You don't know until you have worn geta." This means roughly, "you can't tell the results until the game is over." Long before the 1970s and before platform shoes, Japanese women wore Geta sandals or clogs.
The reason for wearing these very high platform shoes were not for fashion, but for practical reasons. If one were to wear a very expensive kimono that hangs all the way down to their feet, they would not want to get mud on it when they walk outside.
Geta are made of one piece of solid wood forming the sole and two wooden blocks underneath. These blocks may have a metal plate on the section that touches the ground in order to lengthen the life span of the Geta. A V-shaped thong of cloth forms the upper part of the sandal.
The dai may vary in shape: oval ("more feminine") to rectangular ("more masculine") and color (natural, lacquered, or stained). The ha may also vary in style; for example, tengu-geta have only a single centered "tooth". There are also less common geta with three teeth. Merchants use(d) very high geta (two long teeth) to keep the feet well above the seafood scraps on the floor. The teeth are usually not separate, instead, the geta is carved from one block of wood. The tengu tooth is, however, strengthened by a special attachment. The teeth of any geta may have harder wood drilled into the bottom to avoid splitting, and the soles of the teeth may have rubber soles glued onto them.
The hanao can be wide and padded, or narrow and hard, and it can be made with many sorts of fabric. Printed cotton with traditional Japanese motifs is popular, but there are also geta with vinyl and leather hanao. Inside the hanao is a cord (recently synthetic, but traditionally hemp) that is knotted in a special way to the three holes of the dai. In the wide hanao there is some padding as well. The hanao are replaceable. It sits between the two first toes because having the thong of rectangular geta anywhere but the middle would result in the inner back corners of the geta colliding when walking. Recently, as Western shoes have become more popular, more Western looking geta have been developed. They are more round in shape, may have an ergonomically shaped dai, a thick heel as in Western clogs, instead of separate teeth, and the thong at the side as in flip-flops. According to Japanese superstition, breaking the thong on one's geta is considered very unlucky.
Maiko (geisha in training) wear distinctive tall geta called okobo which are similar to the chopines worn in Venice during the Renaissance. Also very young girls wear okobo, also called "pokkuri" and "koppori", that have a small bell inside a cavity in the thick "sole". These geta have no "teeth" but are formed of one piece of wood. The middle part is carved out from below and the front is sloped to accommodate for walking. Pokkuri are usually red in color and are not worn with yukata, but a very fancy kimono (such as at shichi-go-san festivals).
Oiran (花魁), who were high-ranking courtesans of the feudal period in Japan, wore tall, lacquered koma-geta or mitsu-ashi (literally, "three legs"). Unlike geisha and maiko, who only entertained by conversation, singing and dancing, oiran and tayuu were the highest rank in the hierarchy of prostitution in the pleasure quarters. Whereas geisha and maiko wear tabi socks, the oiran and tayuu preferred not to do so (even in winter) and their toes can be seen poking out under many layers of kimono while wearing these tall geta. These shoes were most likely worn to ensure there was no confusion between geisha, maiko and oiran / tayuu. One sometimes sees maiko hobbling along in okobo, but the pace must have been even more arduous in these tall geta.
