Reef Fanning Sandal: It's hard enough to carry your keys, wallet, and phone in that sorry excuse for a pocket on your board shorts and unless you're crafty with a lighter or have teeth made of steel, something has to give. The men's Reef Fanning Sandals come with a bottle opener built into the outer sole. Not only do these flip-flops give you a way to drink your suds, but they feature super plush soles and thick straps that keep your feet comfortable—while you're still standing, at least.
