What is a "flip-flop"?
A flip-flop is a type of open-toed footwear consisting of a flat sole, typically made of rubber or foam, held onto the foot by a Y-shaped strap that runs between the toes. They are lightweight, easy to slip on and off, and are popular for casual wear, especially in warm weather or at the beach. Flip-flops can come in a wide range of colors and patterns, and some may even have additional features such as arch support or massaging footbeds for added comfort. While they may not offer the same level of support or protection as other types of shoes, flip-flops are a convenient and stylish option for many people.
