Free is Hard to Beat If your running style leans toward the shorter-distance sprinter's end of the scale, the lightweight Nike Free RN 5.0 running shoe was made for you. Its stripped-down design includes a single-layer, stretch mesh upper with a second-skin feel and minimal foam in the midsole to provide a tangible ground-contact sensation. The absence of a heel counter adds freedom of movement while maintaining a firm fit. Nike Free RN 5.0 features: Ultralight mesh upper provides maximum flexibility. Offset lacing system reduces pressure on instep. Bootie with integrated tongue gives a seamless fit. Low-density foam midsole promotes a ground-connected feel. Heel-to-toe grooves allow multidirectional flexibility. Precision cuts on outsole and side of midsole optimize flexibility. Rubber pods on forefoot and heel enhance traction.
