Dynamic Flywire Support
The Nike Free Flyknit uses Dynamic Flywire support similar to that of other Nike models. This technology is seen by the thread that pokes out of the upper and doubles as eyelets. When the wearer tightens the laces, the Flywire hugs the foot for a more snug and supportive fit.
Mesh Insole
Mesh-lined insoles play to the minimal and lightweight theme. They are removable, breathable and aid the durability and washability factors that allow wearers to go sock-less.
