    Nike Flex RN 2017: Minimalist feel with flexible support

    Let me introduce you to one of my new favorite running shoes. Ever wanted to try minimalist shoes but feel apprehensive about the lack of support?

    Here’s a nice compromise that won’t break the bank.



    The Nike Flex RN 2017 feels a bit bulky at first, especially if you are used to less drop. The 7mm drop seems to be a comfortable compromise for my current running style and light to medium mileage.

    The stable platform provides a surprising amount of flex, which has served me well for my short to middle distance runs. Great rotation shoes for all runs outside of an end of the cycle marathon training run.


    The midsole has a quirky footbed and I logged a few sessions without the insoles just to get an understanding of the support it adds. Taking the insole out cuts out a few millimeters for an even more minimalist feel, but it also gives you a sense of the extensive support from this bit of criss cross magic. A little too rough to go without, however.



    I recommend taking it for a spin sans insole and then adding back in the foam cushioning that completes the smooth ride. Definitely points for a nice execution on this aspect. I haven’t seen this used this way before and I have to say I’m a fan.


    Uppers are light and airy compared to many of the bulkier shoe and the toe box has ample room to stretch out those little piggies. The right balance between breathable and a secure fit helps you enjoy the shoe immensely.

    They might not hold up over the long run or really challenging terrain, but if you’re mainly a road, track or path runner, you’ve got to check this one out.



    After a number of shoes with bulkier soles and thicker treads, I was reluctant to run in soles with less grip and cushion. Yes, maybe not the best choice for a rainy day or a trail run, but it holds up very well on the road or track.

    Seems to be a solid option for keeping your body guessing and building out a shoe rotation. Plus they’re a nice option as a substitute for a 24/7 or gym trainer, as they’ve held up with consistent mileage so far.


    • Springy, responsive and lightweight trainer
    • Versatile and stylish, can definitely be worn for gym, errands, etc
    • Great features for price


    • Heel can feel bulky at first compared to the rest of the shoe
    • Upper, especially lacing system, is VERY minimal and prone to damage
    • Rocks easily get stuck in gaps of soles



    I have to admit I was a little skeptical at first, being a fan of a more solid feeling shoe with more tread like a Brooks Ravenna or Launch.

    Altra, it’s decidedly high in the drop category but somehow seems to have the right balance to keep me coming back for more.

    Add in the fact that it’s a sharp looking shoe that sports all around casual comfort AND style, you’ll be surprised it doesn’t cost more. Yes, the uppers are a little too thin and could break down along the line, but that’s the sacrifice you’re making for a minimalist shoe.

    In the end, if you are looking to transition from the more supportive shoe and don’t want to ditch all the protection, this is a great opportunity to try something different by Nike.

Updates to Nike Flex RN 2017

  • The Nike Flex RN 2017 is a 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 mid-sole 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.

Nike Flex RN 2017 size and fit

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 mid-sole 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.

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.
