Video reviews and unboxing

  • The Nike Free RN Flyknit 2018 now uses a Tri-Star pattern outsole to replace the auxetic structure found in the 2017 version. It helps the foot to expand naturally without compromising cushioning.
  • The Spandex laces are utilized in the shoe. It aims to create a more personalized fit to suits the preference of the runner.
  • The Dynamic Heel Fit System has been updated. It hugs the ankle and heel to promote a snugger fit.

When it comes to the sizing, the Nike Free RN Flyknit 2018 follows the standard running shoe length. This shoe is designed for runners who prefer to take any long and short-distance running activities to the next level. Available widths are D-Medium for the men’s version and B-Medium for the women’s version.

The outsole section of the Nike Free RN Flyknit 2018 utilizes the Tri-Star pattern, which is also used in some shoes from Nike. It allows the foot to expand naturally without sacrificing its lightweight cushioning and protection. It provides additional traction as well.

Inside a slightly firmer carrier system is a soft Phylon foam core. These features of the shoe make up the Co-molded midsole. This component of the shoe offers additional protection and comfort. It provides the runner with a hassle-free running experience.

The upper is made up of a one-piece Flyknit material which is essential in conforming to the natural shape of the foot.

Its updated construction features a more open weave which results in the better flow of air. It also provides adaptive support and a glove-like fit.

The shoe's laces and the feather-light Flywire cables work together to provide the runner with a more customized fit. These little cables are strategically designed to tighten the laces quickly. As a result, the rest of the upper unit tightens as well. Runners are in control of adjusting the amount of midfoot lockdown by loosening or tightening the laces depending on their needs.

A snugger fit is encouraged by the Spandex laces. It provides a locked-down fit without any feeling of restriction.

The updated Dynamic heel fit system is integrated into the Nike Free RN Flyknit 2018. It stretches and hugs the ankle and heel area to deliver a more secure fit.

Utilized in the shoe is the Anatomical heel. It uses a rounded construction to encourage a more natural heel-to-toe transition. This component of the shoe is made to roll with the ground as the runner strides.

Textured and solid rubber segments are integrated under the heel and toe sections for added durability in the high-wear areas.
