Beach flip-flops are formed by connecting two parts, the upper and the sole. The upper part is made of cotton or polyester fabric, which has the advantage of being elastic, not easy to absorb water, and can reduce water resistance when swimming. The shoe needs to be partially equipped with a fastening strap, and its function is to make the beach flip-flops and the concave part of the sole of the foot closely adhere to each other so that the shoe and the foot are integrated, and the resistance to the foot when swimming is more effectively reduced. The bottom of the foot adopts a soft ultra-thin rubber sole, whose function is to prevent the sole of the foot from being hurt by seafood skin or hard stones, and it can also enable the wearer to experience the wonderful feeling of walking barefoot on the beach.
