Flip-flops are a common type of footwear. They are a thin rubber sole with two straps running in a Y shape from the sides of the foot to the gap between the big toe and its neighbour. The popular use of flip-flops as beach or outdoor wear has spread through much of the world, although it is most common in India and Pakistan (where it is immensely popular and is called a Hawaii chappal), Australia, New Zealand, South Africa, UK, USA, Brazil, Panama, the Pacific Islands, and Southeast Asia.
