Bring back the cheerful, bright neon shades of the ‘80s with these flip flops from Sanuk. They are supremely lightweight with plenty of room for movement and comfort. Made of synthetic material, the straps are soft and rubbery, similar to a jelly sandal. The footbed is constructed from foam for cushy support, while EVA foam forms the outsole for extra durability. The brand’s signature Happy U tread provides traction, and this sandal is fully waterproof.
