Video reviews and unboxing

  • The Nike Flex RN 2017 is a very affordable running shoe that’s great for those who neutral pronation or supination. It’s designed to be lightweight and adherent to the natural movement of the foot. The façade has a clean and consistent look to it. Thin overlays line the forefoot and sides of the shoe, and they do not make it look bulky.
  • The midsole unit features a foam that has two planes of cushioning. The purpose of this design is to keep the experience as comfortable and as consistent as possible. A molded insole adds a bit of contoured support to the curves of the underfoot.
  • Durable rubber-pods are placed in areas of the outsole that are more prone to wear and tear. The rubber material is lightweight yet resilient against the potentially damaging nature of the asphalt. The Auxetic design makes sure to accommodate the natural flexibility of the wearer’s foot.

Standard measurements were used in the making of the Nike Flex RN 2017. The sizing schemes follow the natural choices of runners. The available width for the men and women’s versions is medium, so it accommodates those who have medium feet. The natural curve of the human’s foot is mimicked by this shoe’s semi-curved shape.

A rubber compound is used for the outsole unit of the Nike Flex RN 2017. It is placed in high-wear areas, particularly in the forefoot and heel. Its main purpose is to prevent abrasion, but it also provides reliable traction over the asphalt.

The auxetic tri-star design of the outsole basically makes the platform more flexible. Triangular grooves and spaces allow the sole unit to follow the natural movement of the foot as it goes through the gait cycle. It also assists the rubber in delivering traction.

Phylon is the main midsole unit of the Nike Flex RN 2017. Designed to accommodate the entire length of the shoe, it cushions the entire foot throughout the running session. Its responsive and flexible nature adds to its appeal as a comfortable platform for runners. Also, it has a dual-density nature, which potentially extends its lifespan by preventing early breakdown. The Phylon midsole material is also used in the Nike Flex RN 2018, Downshifter 7 road shoe and other well-known running shoes from Nike.

A minimal molded textile foot-bed is placed right above the main foam unit. It adds a bit more cushioning to the runner. It also mildly traces the contours of the underfoot, giving some semblance of support to areas that are not usually cushioned.

The upper unit of the Nike Flex RN 2017 utilizes Engineered Mesh. This material looks and feels like a woven cloth, which is good for the skin. It’s lightweight and it hugs the foot naturally. It also accommodates airflow.

Thin overlays are printed to the main fabric. They help the upper unit when it comes to hugging the foot and keeping it in place. Their inconsequential disposition doesn’t add weight or make the façade bulky.

A traditional lacing system is used in this shoe. The laces are flat, so they’re easy to loop and lock. The dynamic Flywire cables connect directly to the lacing system. They adjust in accordance with the tightness or looseness of the shoelaces, thus giving a fit that’s tuned to the preference of the wearer.
