Just because you wear the Reef Men"s Phantom Sandals doesn"t mean you also have to wear an uncomfortable white mask and pine freakishly over a girl. But the Phantom flip-flops do have water-friendly nubuck uppers and air mesh linings, so you might be tempted to stroll down to the surf. And while you"re there, a shark might hurl itself out of the water and snark off half your face. Then you might want to wear a mask. At least if that happens, the Phantoms Sandals" EVA footbeds and arch supports will keep the bottoms of your feet comfortable.
