Updates to Nike Free Flyknit 5.0

  • Nike offers very little changes in the Free Flyknit 5.0 to maintain the shoe’s high standards that hordes of people have come to love. What is quite noticeable is the lesser number of welded overlays, especially around the midfoot just where the eyelets end. It is a resounding fix to those runners with more than enough volume in their forefoot who have experienced irritations or hot spots.
  • The upper mesh is lighter and as breathable as before. As the Free Flyknit 5.0 is known for its sock-like fit, this more adaptable mesh takes personalized fit to a more comfortable level.

Size and fit

The Free Flyknit 5.0 has always been known for its amazing features as a casual footwear rather than as a trainer. Seeing that most people use this for everyday apparel, Nike changed the fit a bit. Although it is still fairly regular in the heel and midfoot, the forefoot has more room in volume and width for even more comfort. The available width is medium while sizes are still standard. Sizes are from 6 to 14 for the men’s and 5 to 11 for the women’s.


The outsole displays the sipes configuration for a full-contact underfoot. With a better platform during landing, runners have a very natural way of getting stability in a shoe with excellent minimalist features. The outsole design is also one way of adding flexibility and promoting a more natural running form. Providing durability in high-wear areas is the BRS 1000 carbon rubber. Nike’s use of a decoupled and beveled heel provides better ground contact, isolates shock, and helps with the transition.


The midsole is carved with the same sipes configuration in the outsole for a more natural running form and freedom of movement. A very durable foam that spans the midsole and the outsole is used in the shoe. It is a 40/60 mixture of solid rubber and the Nike-exclusive Phylon for excellent durability and more than adequate responsiveness.


The Flyknit is a seamless upper dominated by a very breathable mesh and a few welded overlays. This iconic technology adapts very well to the foot as it is directly connected to the sole of the shoe. With sock-like fit and no-sew interior, running sockless has never been better. The Flyknit material is also used in the Epic React Flyknit 2 and other Nike running shoes.

The Dynamic Flywire or lightweight and sturdy cables connecting the upper to the midsole provide comfortable security. An asymmetrical lacing wraps the second skin feel of the upper.
