Reef Smoothy Sandals for men. The Smoothy takes Reef way back to the very roots of Reef sandals. The Smoothy is simple with a comfortably woven strap design and Reef-flex triple density EVA construction. This men's sandal has anatomically correct arch support built into its lightweight, cushy footbed. The smoothy is also very durable and grippy with its molded high-density EVA outsole for extra traction. This is a classic beach sandal among classics.
