Flip Flops....

Flip-flops (also called zōri, thongs, jandals, or a variety of other names throughout the world) are a type of open-toed sandal typically worn in casual situations, such as outside or at the beach. They consist of a flat sole held loosely on the foot by a Y-shaped strap that passes between the first and second toes and around either side of the foot. They may also be held to the foot with a single strap over the front of the foot rather than a thong. The name "flip-flop" originated because of the sound that is made by slapping between the sole of the foot and the floor when walking.
This style of footwear has been worn by the people of many cultures throughout the world, originating as early as the ancient Egyptians in 4,000 B.C. The modern flip-flop descends from the Japanese zōri, which became popular after World War II when soldiers returning to the United States brought them back. They became popular in casual settings during the 1960s, 1990s, and 2000s, and some varieties have even found their way into more formal attire, despite criticism.
The use of flip-flops can result in many pains and injuries, including ankle sprains and broken bones. Some individuals who walk for long periods report pain in the feet, ankles, and lower legs. The lack of support provided by flip-flops often results in over-pronation injuries, caused by the foot slipping inwards further than normal. This can lead to flat feet and tendonitis. Other injuries that may result are due to the footwear's open-toed nature, such as stubbed toes, cuts, and bruises. Doctors recommend purchasing pricier sandals with thick-cushioned soles, as well as those that have a strap that is not canvas and that comes back almost to the ankle.
