The next best thing to going barefoot, the Vibram Five Fingers Collection ($75-$125) is designed to let you walk, run or hike at your most natural. Available in a number of different models, these hardcore kicks offer protection and comfort with breathable stretch mesh and polyamide upper, TC-1 performance rubber sole for added traction, and a layer of antimicrobial microfiber footbed to minimize your foot funk.
