Here are the weird adhesive soles you never asked for (though they do appear to be useful).
Called Nakefit, this pair of freaky stick-on shoes adhere to the bottom of your feet to protect them from things like hot sand and rocks. They're waterproof, hypoallergenic, have anti-slip pads and, should you need an unusual way to cover your tootsies, available to pre-order on Kickstarter.
