Flippers, also known as fins, are a type of footwear designed for swimming and water activities. They are typically made from flexible materials like rubber or silicone and are worn on the feet to enhance propulsion in the water. Flippers come in various sizes and styles, catering to different activities such as snorkeling, scuba diving, and surfing. These accessories help swimmers move more efficiently by increasing the surface area of their feet. By providing better thrust and speed, flippers allow users to navigate through water with less effort. They are popular among both recreational swimmers and professional athletes for their performance benefits.
