The Zilch by Teva is a sport sandal for minimalists, and it lives up to its name. With a thin footbed and highly flexible design, you'll want them mostly for casual hiking and camping. Plus you can fold them away at a whim.
Don't expect to do anything too out of the ordinary in these, though. They're just a step above walking barefoot, even if they're more than your average flip-flop. $80. [GearJunkie]
