Unless you're crafty with a lighter or have teeth made of steel, something has to give. Good thing Reef knows what's up—the Men's Fanning Sandals come with a bottle opener built into the outer sole. Finally, a way to open your microbrews without resorting to a European carry-all. 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.
