Nike Free Flyknit 4.0 review

The Nike Free Flyknit 4.0 is a great looking shoe. It combines a seamless upper with multiple colors with a sleek, low profile. I would consider the 4.0 a pseudo lifestyle shoe because of all the people I see wearing it while I'm out and about.

The knit pattern really stands out, and looks great while going for a run, or grabbing a bite to eat. It's no surprise that Nike has continued to make shoes that look very much like it.

Runs a bit small

Because of the Flyknit material, this shoe can be bought a tad bit small but will still fit fine. The Flyknit really stretches to fit your foot and is extremely comfortable once it breaks in a little bit. When I went shopping for a pair of these, they only had a half size smaller than my usual size in the color I wanted.

I decided to try them on, and although they fit a little snug, I decided to keep them. A week or so later, the Flyknit had stretched out to accommodate my foot and I had that sock-like fit that I wanted for this shoe.

No heel slip

Also, the back of the shoe really locks your foot in and doesn't allow for any heel slippage. The Flyknit 4.0 is a snug-fitting shoe that has a great fit due to the Flyknit upper.

Worth the price

Anything that Nike makes with Flyknit usually has a higher price point. The Flyknit 4.0 has a retail price of $165 CAD, and while that is a bit high, I believe that it's worth it for the shoe that you get.

It is a very versatile shoe and the Flyknit upper is a great addition. If not for the Flyknit upper, then the most I would pay for this shoe would be $120 CAD. The free midsole is lacking in cushioning compared to Zoom and Air.

The Nike Free Flyknit 4.0 is extremely flexible

Like any Nike Free Flyknit 4.0 is an extremely flexible shoe. It's flexibility makes it feel as though you are running with barely anything on your foot.

Feather-like weight

Combined with the sock-like fit and feather-like lightness, this shoe truly exemplifies barefoot running. Don't be fooled by the "barefoot running" advertising however.

Suitable for daily runs

This shoe has enough cushioning to get through those daily runs, unlike some other barefoot running shoes.

The Flyknit 4.0 is also a fairly comfortable shoe. While not as cushiony as the Zoom or Air midsoles, the Free midsole provides adequate cushioning that should last quite a while.

However, I personally found that this shoe isn't super responsive while I was doing some speed work with it. Nevertheless, the Free Flyknit 4.0 is a well-performing shoe for various purposes.
