Now that you're packing a cellphone with a vibrating touchscreen, have glasses that rattle your brain if you try to get a bit of shut-eye, and nod your head to the beat of your rumbling headphones, why not put a little shake in your shoes, too? The cleverly named Good Vibrations might sport a website that was probably built in Marky Mark's heyday, but the kicks it sells claim to be therapeutic in nature. The thick-soled shoes feature a non-stick grip, on / off switch, and a rechargeable battery that reportedly provides around five hours of feet shakin' therapy. Designed to massage away the aches and pains throughout the day rather than after the damage is done, these unisex slip-ons are constructed with Spandex, lined with suede, and just might cause fits of laughter if you're the ticklish type. The Good Vibrations shoes are strangely available in just four sizes, leaving most of you with a bit too much (or too little) room inside, but for just about 60 bucks, the fun factor here is probably enough to put aside the fact that they aren't likely to fit.
