Beach sandals consist of uppers and soles. The upper part is made of nylon or polyester fabric, which is elastic and difficult to absorb water, and can reduce the resistance of water when swimming. Shoes need to be equipped with a fastening belt, which is used to make beach shoes and the concave part of the sole closely fit together, so that shoes and feet can be integrated, and the resistance to feet can be reduced more effectively when swimming. Soft and ultra-thin rubber soles can prevent the soles from being pricked by hard stones of crustaceans or marine animals, and also allow the wearer to experience the wonderful feeling of stepping barefoot on the beach. Although most beaches are exquisite, places with reefs are very dangerous. If you go to sea here, it is a good choice to wear beach sandals that fit your feet.
