Reef Dram Sandal- The Reef Dram Sandal eliminates the problem of carrying too much stuff to the beach. Instead of lugging a heavy cooler all the way from your car, these sandals let you keep your drink right in the heel of your shoe. That’s right, the polyurethane encapsulated canteen in the heel of these sandals opens with the included reef church key/fin key. Think that’s cool? We do too.
