Made for short runs, from your daily 5K to that spontaneous sprint, the Nike Free RN 2018 Women's Running Shoe is as flexible as ever. The innovative sole has an updated design, yet still delivers a comfortable, barefoot-like feel. Easily worn with your everyday outfit, or packed in a tote or backpack for a quick change, these are the most versatile in the Free RN family. So you can be up for anything. Better Fit The upper material has elastane for a more dynamic, improved fit than before. Still lightweight and soft, the upper is easy to collapse, so you can quickly slide the shoe into your tote or backpack. Upgraded Comfort A wide strap wraps your heel for added support, better structure and a more secure fit. Padding in the heel adds another level of comfort. All-Natural Movement The soft, lightweight sole mimics your foot's natural movement through its innovative pattern. It expands and contracts with every landing and push-off. This provides a natural feel and a barefoot-like sensation, kind of like an extension of your foot.
