Nike Free 4.0 Flyknit Review
Pros and Cons
Of course, this Nike Free 4.0 Flyknit review includes the advantages and disadvantages of this shoe.
- Sock-like upper
- Uncertain durability
- Sole picks up lots of stones/rocks
- Severely lacking in traction
This Nike Free 4.0 Flyknit review will tell you why many runners consider this pair to have one of the best uppers in a shoe that they have ever tried. It upper actually feels like a second skin and does not cause any discomfort even on long, rainy runs.
An entirely redesigned outsole pattern and the Flyknit upper are two new features of the Flyknit 4.0. The Flyknit upper truly does an amazing job on the shoe. Even when you just try it on for the first time, the feel and fit of the upper is incredible. This is a huge development from the Free Flyknit+, which was tight and narrow, and has a toebox that is entirely curved. This version of these running shoes fits true to their size.
The midsole of the Nike Free 4.0 Flyknit is made from Phylite, which is basically Nike’s version of blown rubber substance. It works as a foam that is a strong enough material for the outsole. It gives a quite firm, but reasonably cushioned ride, a standard ride for equally minimal and lightweight shoes.
Unfortunately, this Nike Free 4.0 Flyknit review discovers that Nike did only a little past the midsole. They just added the least amount of rubber pods below the outer corner of the heel and under the big toe. This means that 90% of the outsole of the shoe is only exposed midsole.
Also, although a blown rubber works okay in moderation, an actual rubber used at contact point can immensely help, particularly in improving traction. Nike failed to create a shoe that has minimal traction on any surface beyond the pavement. These running shoes would even slip on moist pavement, so do not bother to try to go up a hill with damp grass.
These exposed midsole materials also create issues on the durability of the shoes. Each run is taking off thin coatings of the cushioning material.
If the sole is somewhat disappointing, this Nike Free 4.0 Flyknit review proves that its upper is its redeeming attribute. It is easily the most comfortable upper that you will ever have on your feet. It has a little stretch, so the upper moves with your feet just like a stronger, thicker version of socks.
