Supposedly nothing gets you springing about better than being barefoot. It's probably why kids are so active, and I've not left this desk-chair in six years. Owners of Vibram's Five Fingers shoes, like Sergey Brin, can attest to that.
These stickers grip heels of the feet, as well as toes or whatever other part is needed, to give better grip when playing indoor sports. Playing barefoot gives you more flexibility than wearing shoes ever does, allowing you to twist with ease. Designed by Frieke Severs, these Footstickers aren't real—but definitely should be.
