Benefits of Barefoot

The benefits of walking and running barefoot have long been supported by scientific research, coaches, and athletes who've offered ample evidence that training without shoes allows you to run faster and further with fewer injuries.

Motion studies demonstrate that when walking and running barefoot, one naturally lands on the forefoot, directly below your center of gravity. This results in optimum balance, increased stability, less impact, and greater propulsion. According to Dr. Ivo Waerlop of the Vibram Biomechanics Advisory Board, "Running in Vibram Five Fingers" improves agility, strength, and equilibrium, plus it delivers sensory feedback that allows runners to make immediate corrections in their form. This greatly improves running efficiency." 

No footwear comes closer to recreating the experience and natural sensation of running barefoot than Vibram Five Fingers. It delivers all the health and performance benefits of barefoot running–with less the risk of injury. The patented Vibram sole acts like a second skin to protect you from elements and obstacles, so you can reap the rewards of barefoot running.
