Okay, so maybe this isn't your typical geek paraphernalia, but if you geeks are like most of the folks I roll with, you'll probably be into it. The new Reef sandals feature a James Bond-meets-frat boy function that cannot be ignored - the heel is home to a polyurethane encapsulated canteen with a screw cap. Are you planning on crusin' the boardwalk or camping with your friends and want to store the rest of that drink until later? Slip it into your shoe. You can get your own for $45. Liquid of your choice not included.
