Updates to Nike Free RN Motion Flyknit 2017

  • The Nike Free RN Motion Flyknit 2017 is designed for long and short-distance training runs. It features the innovative and flexible Free Sole for a naturally flexible and responsive underfoot experience. This design basically provides the feeling of a minimalist shoe.
  • Because of the elimination of the traditional laces, the two-strap system acts as both the fit adjustment component and a visual element to the shoe. Its mid-sole unit has two foams that provide a good combination of support and comfort. The whole platform aims for a better and smoother ride.

Size and fit

When it comes to sizing, the Nike Free RN Motion Flyknit 2017 has a standard shoe length. This shoe is best for runners who prefer any type of long and short-distance running activities. Available widths are D – Medium for the men’s version and B – Medium for the women’s version.


The outsole unit of the Nike Free RN Motion Flyknit 2017 has an Auxetic Tri-Star pattern. This design causes the entire platform to follow the runner’s movements in an attempt to deliver a smooth and natural underfoot experience. This material is also used in the Free RN Motion Flyknit 2018 and other running shoes from Nike.

Rubber is sparingly added to the heel and forefoot sections. The purpose of this material is to provide traction and to stave off wear and tear.


The midsole of the Nike Free RN Motion Flyknit 2017 is made up of a Dual Density Fused Lunar Core. It is primarily where the foot relaxes. It essentially offers responsive cushioning to the foot of the wearer.

The ‘core’ foam unit is actually placed inside a carrier system. Called the IU002, it responsibly cradles the rest of the mid-sole and keeps it in its robust form. It’s strong, but it’s not stiff, so it still allows the runner to naturally flex the foot.


The upper is connected to a 4-Way Stretch Strobel. This allows the Auxetic pattern of the outsole to flex naturally with the runner’s foot.

The Nike Free RN Motion Flyknit 2017 has an Anatomical heel construction. It allows the base of the platform to go through the gait cycle in a smoother and more natural fashion.

This shoe also features a Flyknit Upper. This is an overlay-free, one-piece upper that results in a sock-like and seamless fit.

The Velcro Strap design offers an adaptive and customized fit. The need for laces is eliminated. The strap is used to ensure easy and pressure-free adjustments to the fit.

It has a Mid-cut collar that holds the lower portion of the leg like a sock would. The garter-like construction is meant to offer a more secure coverage.
