The term 'BEACH SHOE' can be broken down into two crossword solutions: THONG (5 letters) and SANDAL (6 letters). A THONG is a type of footwear that consists of a strap between the toes and another strap around the heel, with no material covering the top of the foot. Sandals are a type of open-toed shoe that typically have straps around the ankle and across the top of the foot. Both thongs and sandals are popular choices for beachwear due to their lightweight and breathable design.
