Swim fins, also known as flippers, are specialized footwear designed to enhance swimming efficiency. They are typically made from flexible materials like rubber or silicone and are worn on the feet. Swim fins help swimmers propel themselves through the water more easily, allowing for faster speeds and improved maneuverability. These accessories are commonly used in various aquatic activities, including snorkeling, scuba diving, and competitive swimming. Swim fins come in different sizes and styles, catering to both beginners and experienced swimmers. They can also aid in building leg strength and improving overall swimming technique.
