Let me tell you right off the bat…these shoes have the most flexible soles of any that I’ve tried. And by flexible, I mean it bends, squeezes, squishes, and moves in all directions with ease. For a fairly thickly padded shoe, this auxetic sole design that Nike invented is super effective. I feel that only VFFs can move in a similar manner.
When I first saw the preview for these shoes, I got really excited and hoped that they would be good or better than the Lunarepics. For one thing, Nike is advertising a 4 mm heel drop (20/16 mm) and while I realize that heel drop may not necessarily be such a big factor anymore, I do find that it makes a big difference to me. Additionally, the Lunarepics are on a 28/18 mm high platform, which I find is a touch too thick no matter how comfortable I feel in them.This Flyknit thing…it can be pretty and it can be pretty ugly. Take the Lunarepics, for example, I really like how they look, especially the Gyakousou colourway. On the other hand, they have made some stinkers in the past with the buy nike free shoes and Free 3.0.
I understand that beauty is in the eye of the blah blah blah but in this case, I don’t think anyone will disagree that the RN Motion is pretty dull and unassuming. The knit and design is laid out in a straightforward and simplistic manner. The Flyknit is ribbed providing it with a bot more texture without sacrificing its inherent sock-like quality. It feels thinner than what they used for the Lunarepic.
Inside, there is no tongue or any kind of a removable insole so what you see is what you get. The laces are a bit redundant but I suspect they will come in handy during faster paces to prevent slippage.
Nike refrained from embedding any kind of fancy designs or patterning into the knit other than straight lines originating from the base of the shoe towards its laces.The prettiest thing about the whole Mens Nike Free 3.0 V3 also happens to be the most effective: its sole.
Nike applied an Auxetics design concept that allows the shoe to expand at least a size length-wise and cross-wise as the foot moves. The “Free” concept has always been about mimicking the natural movement of our feet but so far, Nike really hasn’t come close. Even with flex grooves cut in all directions, the thickness of the sole always made it feel stiff and clunky.
In using this design, they feel that they have stumbled onto the right formula. Interestingly enough, auxetics has already been used in shoes before with the introduction of the UnderArmour ClutchFit albeit on the upper only.
