Chappals are famous with various names all over the world. They are called thongs, jandals, pluggers, go-aheads, slappies, slides, step-ins, chankla and most popularly flip-flops. The name 'chappal' is mainly used in India, Pakistan and other nearby countries. They are basically open-toed footwear generally matched up with casual wear.
They consist of a flat sole, which is held loosely on the foot by a Y-shaped strap that passes between first and the next toe. However, the designs may vary. Many chappals can be held to the foot with a single strap. Chappals were given the name of flip-flops because of the sound it produces by slapping between the sole of the foot and the floor when walking.
The custom of wearing chappals originated in Egypt in around 4,000 B.C. The modern chappals resemble the Japanese footwear, which became popular after World War II when soldiers returning to United States carried them back.

Various materials like rubber, foam, plastic, leather, suede and even fabric is used in manufacturing chappals.
