  • The 2016 version of the Nike Flex RN uses the proprietary Flywire cords as its most significant development. As most Nike fans know, the cords are directly attached to the midsole and then looped through the laces. The cords greatly help in holding the foot down without the use of too many overlays.
  • With the Flywire cords available, Nike also utilizes a very light single-piece mesh for breathability, support, and security that is not restrictive. The upper also sees the removal of the stitched overlay on the toe box and replaced with a thin, welded version. It gives more room in the forefoot and enhances breathability.
  • The heel gets a little help through the addition of welded overlays. These welded overlays are quite pliable, so there is just enough heel support without too much stiffness.

The fit of the Nike Flex RN 2016 continues to be snug from the heel to the forefoot. Runners should get more midfoot hold courtesy of the Flywire cables. There is just enough room for the toes to wiggle in the toe box. Runners with narrow to medium feet are built for this kind of fit. Sizing is accurate in the shoe.

The underfoot features the unique siped Nike outsole where the Tri-star configurations are scattered throughout. It gives the 2016 Flex RN plenty of flexibility as the pattern creates numerous cuts all over the outsole. The heel and the area beneath the big toe are covered with hard carbon rubber for durability while blown rubber makes up the rest of the outsole.

The no-fuss midsole is occupied by Nike’s patented Phylon foam for consistency in cushioning, responsiveness, and durability. As the foam covers the whole midsole, there is enhanced motion through the gait cycle.

This midsole material is also present in some Nike road running shoes like the Flex RN 2018 and Nike Downshifter 7.

The lightweight, engineered mesh offers exceptional breathability and a sock-like fit. Nike uses for the first time in this series the Flywire cords to help with midfoot security and locked down feel. Welded overlays also help with the support and structure. The ankle collar and tongue have decent padding. A traditional lace-up closure clinches the fit of the Nike Flex RN 2016.
