85 / 100 based on 12 expert reviews

  • 84 / 100 | Eric Kim Photography | | Level 1 expert

     It fits like a sock, is uber-flexible, and breathable for your long sessions on the streets.

  • 80 / 100 | One Up Reviewz | Level 1 expert

    Great for gym and running. A great workout shoe.

  • 86 / 100 | Running Shoes Guru | | Level 5 expert

    The auxetic construction in the Motion Flyknit is the most prominent, providing the most natural run that the FREE lineup has offered to date.

  • 90 / 100 | 9 Run | | Level 3 expert

    The prettiest thing about the whole shoe also happens to be the most effective: its sole.

  • 90 / 100 | Running Competitor | | Level 2 expert

    And yet the shoe didn’t feel minimal—the cushioning underfoot is enough so you don’t have to brace yourself for touchdown on any surface, but they don’t feel at all marshmallowy.

  • 83 / 100 | Pocket-lint | | Level 2 expert

    It is not a soft run by any means, and we wouldn’t feel comfortable running more than 10km in them for fear of our calves and an overall lack of ankle support, but there was plenty of spring to cope with bursts of acceleration

  • Nike comes up with an innovative and revolutionary design in the outsole that take free running to an even better level. It calls the new technology as having “auxetic properties” that allow the shoe to move laterally and medially with the foot. This is a technology that delivers custom-like support and structure to every part of the shoe.
  • Another new technology in the offing is a new midsole foam set up. The two layers of foam are molded together to give responsive cushioning with an element of on-demand stability.
  • The upper also features a new 3D Flyknit that hugs the skin with every stride and a Strobel that affords added cushioning and comfort without taking away ground feedback and the natural running principle of the Free RN Motion.

The fit of the Nike Free RN Motion from the heel to the forefoot is quite snug in a comfortable way. There is almost a sock-like feel that is in no way constricting. Runners can enjoy enough space in the forefoot for the toes to splay. Medium is the available width of the shoe. Sizes are accurate in options 6 to 17 for the men’s and 4 to 12 for the women’s.

The outsole looks ordinary in its siped configuration, which is known to add excellent flexibility. However, Nike uses an innovative geometric pattern to give the outsole almost a natural flexible movement that works in conjunction with every stretch of the foot through the gait cycle. It creates a new process that even the outsole really moves like a second skin.

The midsole is a mix of the responsive Lunar foam that is enveloped in an IU foam. Nike shapes the new midsole to form a wall, which is also elevated on the medial side. It creates a guide that only produces a corrective measure that is evident only when the runner excessively rolls inward after landing. This midsole configuration is also utilized in the Nike Free RN Motion Flyknit 2018 and other Nike running shoes.

There is stability for neutral runners as well, particularly those whose form suffers after long hours on the road. The new design works with the 8mm offset for a more effective and smoother heel to toe transition. 

A 3D Flyknit upper covers almost the entire shoe that it feels like a sock with a midsole and an outsole. Nike’s natural running principle behind the Free line is substantially displayed in this Flyknit. The heel is quite pliable and completes the second-skin feel of the Free RN Motion. Traditional laces keep the fit secure all through the run.
