They may not be the first vacuum shoes to emerge in concept form, but these so-called Foki shoes from designer Adika Titut Triyugo are certainly the most stylish -- at least in an ASIMO chic sort of way. They also boast a few new tricks not seen before, including an LED display on top that indicates how much dirt you've picked up, and a unique deign that allows them to be completely folded up when not in use. Of course, "concept" is the key word here, but we've got to guess there's an untapped market out there for wearable appliances. Dust Buster gloves, anyone?
