Once thought to be strictly reserved for psychopaths with little will to live, running barefoot, or as close to barefoot as possible, is now considered a great way to train. The Zemgear 360 Ninja Split-Toe Running Shoes ($50-$60) features include a unique split-toe design, tech bands in the upper for stability, and Gecko-Grip rubber pods for traction. At just 2.5 ounces, they also weigh less than the amount of mental anguish that most psychopaths carry around with them.
