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. Ultra-light 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. Rounded heel is made to roll with the ground as you stride. Foam outsole with rubber the toe and heel for durability. Please read. Box is damaged.
