They're definitely not the best looking shoes around, but if your goal is to get as close as possible to a barefoot running experience, the Zemgear 360 Ninja Split-Toe Running Shoes ($50-$60) are a step in the right direction. Features include a split-toe design, phylon outsole, tech bands in the upper for greater stability, a round-toe pattern for increased flex, and Gecko-Grip rubber pods for traction. Overall, they weigh just 2.5 ounces, or just slightly more than some socks.
