The Reef Men's Classic Low Sandal is a sturdy leather flip-flop you'll be wearing for years. The Classic Low's extra-thick 3mm leather footbed has a built-in anatomical arch made from spongy microcell rubber that will mold to your foot as you wear it. The smooth look of the Classic Low Reef sandal means it's just the ticket for semi-formal events when you're not sure if you can get away with just sandals.
