The Nike Free RN 5.0 2020 is a huge leap forward in the evolution of the Free. Lighter and closer to the ground than previous versions, it gives you a "barefoot" feel for a more natural running experience. Secure Comfort A new lacing system helps keep your foot secure while you run. Non-stretch material throughout the upper holds your foot in place, while 3 foam pods in the heel add extra stability. Seamless Design The shoe's bootie construction is integrated into the tongue for a snug, seamless fit. A pull tab at the back of the heel adds easy entry.
