Name: Mens Nike Free Everyoay shoes charcoal black grey
Nike introduced the Free concept in 2005 as a way of conjugating the principles and advantages of running barefoot to strengthen the feet and legs with the protection and traction of a training shoe. Nike Free shoes come in 3.0, 5.0, and 7.0 flavors. For people looking for a more barefoot running experience then the Nike Free 3.0 probably makes the most sense. For people who want to slowly transition into barefoot running by building up foot strength that where the Nike Free 5.0 or 7.0 makes sense.
