Designed for shorts runs, the Nike Free RN 2017 Men's Running Shoe is the most easy-going of the Free family. The innovative sole lets your foot flex and expand naturally. They're easy to pack in a tote or backpack and have a simple style that fits in with an everyday outfit—so you could get in a few unplanned miles. Breathability Soft, lightweight material has a more open knit stitch on the top of the foot for more breathability, helping your feet stay cool. It's thinner and closer to your foot than previous versions. Yet, still provides a secure and substantial feel for wear all day, all year, almost anywhere. Natural Movement The Nike Free sole provides the feel of a minimalist running shoe. It moves with you, mimicking the movement of your foot by expanding and contracting with every landing and push-off, for a natural feel. Ultralight Support Strong, yet feather-light Flywire cables work with the laces to provide more support as you tighten them. A set of cables has been removed from the top lace to allow for a smoother, less distracting feel when you bend at the forefoot.
