According to one barefoot-running advocate, “The foot is the greatest disciplinarian. You can’t overpronate, can’t overstride. If you do anything wrong, the foot will tell you, ‘Uh oh, don’t do that.’” Still, if you’re not ready to give up your running shoes, then the X-Talon 190 from Inov-8 might be the next best thing. This ultralight barefoot cross-trainer puts only 3 millimeters of material between you and the ground, so your feet can always feel what they’re doing. It’ll help train your stride to land on the midfoot rather than the heel, better for long-term foot health. Great stability, comfort and stylish good looks make them fine for walking around town, too. $110 at www.zappos.com.
