We’ve all done it. Gone to the beach and either lost our keys or had our wallets stolen. Or at the very least feared at the potential of one if not both happening. You no longer have to live in fear thanks to the ArchPort Flip Flops, which feature a hidden storage slot large enough for keys, credit cards and perhaps even a svelte smartphone. The flip flops are made from a water resistant material and they’re available in black or blue. Amazon sells them for $55.
