Flip-flops are a type of casual footwear characterized by a flat sole and a Y-shaped strap that passes between the first and second toes. They are typically made from materials like rubber, foam, or plastic, making them lightweight and easy to wear. Flip-flops are popular for their simplicity and comfort, often worn at the beach, pool, or during warm weather. These shoes are known for their breathability and ease of use, as they can be quickly slipped on and off. While they provide minimal support and protection, flip-flops are favored for their convenience and casual style, especially in summer or tropical climates.
