Updates to Nike Free RN Flyknit 2017

• The Free RN Flyknit 2017 has a few updates from its predecessor. The biggest improvement was made on the design of the upper. Replacing the ridged exterior of the shoe is a smoother, one-piece fabric that is overlay-free. This seamless design provides a sock-like fit, which follows the movement of the foot more naturally.
• The logo on the tongue was also updated into something slicker and reflective. Replacing the former logo which looked like it was just stamped on, the updated logo now goes well with the modern exterior of the shoes.
• The dynamic Flywire technology is still integrated into the lacing system of the shoes, delivering a more customized fit. But the system now has the addition of a single eyelet, found at the bottom, for added security. A set of cables has been removed from the top lace of the shoes to allow more flexibility and a look that’s less distracting.

Outsole

The outsole of the Nike Free RN Flyknit 2017 is unique. It has auxetic structures, which adjust to every step. These structures stretch and expand upon impact, keeping up with the foot’s pace and movement. The auxetic outsole also helps give the shoes moderate traction.

Midsole

The midsole of the Nike Free RN Flyknit 2017 uses a fused Lunar Core to deliver a responsive ride and soft underfoot cushioning to runners. This lightweight material is durable, protecting the shoe from early breakdown.

An IU002 Carrier system is also present in the midsole. This system mainly contributes to the soft cushioning and resilient ride of the shoes. It also gives optimal flexibility when needed.

Upper

True to its name, the upper is made up of Flyknit material which conforms to the shape of the foot. Aside from providing zoned stretches, it also allows the shoe to be breathable throughout. The material, which is used in the 2018 version of the Free RN Flyknit, also provides a snug fit.

The heel is rounded in order for the shoe to roll with the ground on heel-strike. There is also a single seam on the inside of the heel so the entire design of the shoe looks like a single piece.

Feather-light Flywire cables work together with the laces to provide the wearer a more customized fit. These tiny cables are strategically placed on the upper of the shoe so when the laces tighten, the rest of the upper tightens as well.
