The term 'Sandal Type' refers to three different types of sandals: THONG (5 letters), Slipon (6 letters), and Flipflop (8 letters). THONG sandals are a type of footwear that have a strap between the toes and the sole of the foot. Slipon sandals are a type of sandal that do not require any straps or buckles, and are simply slipped on and off. Flipflop sandals are a type of sandal that consists of a flat sole with two straps that go between the toes and the heel of the foot. All three types of sandals are popular in warm climates and are often worn for casual occasions.
