    Nike has done a good job here and keeping this off your feet  when you’re not running is probably going to be the hardest part of putting this shoe in your closet.

    The Free Run sole is just as flexible as previous usages of the technology, although the foam content is softer for a more cushioned ride

    The Free Rn Flyknit is in line with what Nike Free’s have looked like in the past but with the added Flyknit technology on the upper and unique cushioning on the sole.

    They have more cushion, springier sole which is really good for the average runner going for 3 to 5 miles of running.

    While the latter is great for those looking for a natural ride, I personally prefer the more cushioned ride that the Lunarepics offer.

Updates to Free RN Flyknit

The major update of the Nike Free RN Flyknit is in its midsole. It is redesigned to enhance flexibility. It utilizes the IU002 carrier system that provides a soft cushioning while enhancing flexibility.

It also features the Auxetic Tri-Star outsole that is designed to give added traction and flexibility in each step. With this outsole, the foot moves more naturally and comfortably.

Free RN Flyknit size and fit

The Nike Free RN Flyknit is ½ size larger than the standard running shoe size. It is narrow in the heel and has low volume in the midfoot. This shoe is available in standard D and B widths for men’s and women’s version. This shoe accommodates comfortably those with narrow to medium-size foot measurements.


The outsole of the Nike Free RN Flyknit is made up of durable rubber material that gives reliable traction while running on the road. Along with this is the Auxetic Tri-Star geometry that delivers maximum flexibility in each step.


The midsole utilizes the IU002 carrier system that is engineered to provide a soft cushioning and responsive ride. This works perfectly with the fused lunar that gives added cushioning for protection and comfort.


The Nike Free RN Flyknit features a single-seam Flyknit upper that provides a sock-like feel while giving maximum breathability. The Dyanamic Flywire cables are woven into the upper to provide necessary support in every step.
