If you can keep a house in your pocket, why not store a tent in your sneakers? The Sibling Collective created a pair of sneakers called Walking Shelter that store a simple tent in mesh netting attached to the back. While the concept is functional, it's hard to imagine that people would actually wear these things… unless sneakers doubling as storage becomes a new footwear trend. ''Oh, you got a tent in your sneakers. That's cool. I got a blow up yacht in mine.''
