I will go to the beach. But my mother told me not to go barefoot on the beach. Because mom says that beach sand contains many types of harmful glass bits and syringes.
Most beaches are cleaned daily so there are less chances of finding anything that may injure your feet. But watch out for sea shells, stepping on those will feel like you jumped in a pool of legos.
Actually it is good to walk barefoot as it removes the negative energy within you and energises you positively and also has an accupressure effect under your feet.
