External Design NIKE Free 4.0 Flyknit:NIKE Free 4.0 Flyknit

This model has really well-thought-out design.

The upper is not one single material. It’s actually woven together with different materials to make one single piece, which will work great, look really cool and make you feel comfortable.

The toe box area is more structured around the toe and very thin and stretchy overtop your toes, allow for that natural flexibility, nice breathability, and ventilation throughout the entire shoe.

The heel made of a non-stretch material, that provides great structure and support.

The upper has a tighter more like a sock-like fit on your foot.

Out laces down the middle are pretty straightforward.

Going down the sides you have a Flywire system, that provides you structure in the midfoot, so it’s going to lock everything in place and keep you nice and secure when you are running.

There is a new free 4.0 outsole for 2014 has that same hexagon cut out that you can find on the other 2 models (3.0 and 5.0), but has offset six mm.

That means that heel has 6 mm higher than the forefoot. Outsole made from the same kind of material.

It`s fairly dense but at the same time provides a nice amount of cushioning underfoot.

The insole is fully removable, it has mesh liner on top with and the insole is orthopedic.

Wearing Advantages NIKE Free 4.0 Flyknit:NIKE Free 4.0 Flyknit

  • Weight:

The Nike Free 4.0 Flyknit is an extremely light shoe that uses a lighter-weight upper material than traditional shoes called Flyknit.

And together with the Flywire system (strong filaments are applied to a minimalistic shoe upper, reducing weight), it creates Nike’s lightest footwear.

  • Enhanced Movement:

Hexagonal flex grooves offer six points of flexibility to let your foot move naturally in every direction.

Secondary cuts in the midsole enhance the natural range of motion.

  • Natural Stride:

With a 6mm offset between heel and forefoot height, the Nike Free 4.0 Flyknit features a very low-profile midsole and a rounded heel to encourage a more natural footstrike.

  • Support:

The strong, lightweight Flyknit upper provides a contoured, supportive fit with stretchy polyester yarn.

Flywire integrated with the laces delivers added support and an adaptive fit.

  • Durability:

Solid rubber under the toe enhances traction and durability.

  • Breathability:

The upper made with the woven material, which allows lightweight breathability and a personalized, much snugger, sock-like fit on both your forefoot and mid-foot.

Also, the construction of the upper is seamless so it ensures irritation-free sockless wear.

  • Sock Liner:

In this model applied the molded sock liner, which mimics your foot’s shape for added support.

  • Damping:

Another improvement of these shoes – waffle outsole pistons – absorbs impact and adds responsiveness.

  • Eyelets:

The model has asymmetrical lacing, which reduces lace pressure.

  • Another Know-How, That Supplied In A Model:

Flyknit – is a revolutionary new system, which uses state-of-the-art integral knitting techniques to create a one-piece upper which is virtually seamless.

The upper appears to use a combination of flechage (short row knitting), intarsia, jacquard, tuck stitches, and stitch transfer techniques to impart shape and function and employs a binding-off technique to close the selvages.

Flywire technology consists of strategically placed filaments that function like cables on a suspension bridge to offer support precisely where it’s needed.


NIKE Free 4.0 Flyknit Running Shoes are very comfortable shoes (even just from the box).

It provides a flexible, breathable, and soft, pretty much like sock-wearing experience.

It can be wearied with or without socks.

This model extremely comfortable and can be used for uptempo runs, recovery runs, hill workouts, gym, cross-training, soccer, casual wear, etc.

But it’s a running shoe, not training.

That means, that you probably not get the support that you would require from a pair of shoes, but this model will be great for straight-line running.

Also, this model tighter through the midsole and a half size smaller, so keep it in mind.
