One big negative this year is that I wouldn’t recommend wearing them without socks. Historically, that has been something I really like about the Nike Free FlyKnit models but the 2017 model FlyKnit upper is a little more coarse and harsh on your skin so definitely make sure to wear socks. The other reason I wouldn’t wear them barefoot is that the heel has a new strip of material on the inside that can ultimately end up causing blisters.
The outsole is perhaps the most interesting part of the 2017 edition. It has a tri-star pattern that is cut into the foam—it looks exactly like a web of triangles. The 2016 shoe had a flexible interconnected geometric-design outsole pattern; the 2017 tri-star evolution improves on this, extending equally both vertically and horizontally to match the movement of the feet. It offers the same grip as its predecessor on most conventional surfaces, such as concrete, a sand track or the treadmill surface. There is extra protection on the front and back of the outsole, for your toe and heel.
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.
Nike Free RN Flyknit 2017 size and fit
The Free RN Flyknit 2017 is larger than the usual. Online retailers suggest getting one that’s half-a-size small in order to get a more comfortable fit. Widths for the shoes also come in standard measurements. Because of the cone-shape of the toe box, these shoes will best fit narrow and medium feet.
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.
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.
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 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.
