Good to know

With fitness regimens constantly evolving, Nike delivers a host of updates to the Free TR Flyknit 3 that would allow women to cope up with the intense demands of today’s workouts.

The midsole of the Nike Free TR Flyknit 3 doubles as its outsole. This foam compound is engineered to be lightweight and durable.

The outsole features a honeycomb tread pattern that facilitates multidirectional traction. It also has sipings that extend to the sides of the sole unit to facilitate natural foot flexion. Both features are concentrated in the forefoot area where bending of the foot occurs.

As for the heel, it is constructed to be flat to give stability to the rearfoot. Rubber pods are strategically placed in the high-wear areas but are more prominent in the heel for improved durability, traction, and steadiness.

The Nike Free TR Flyknit 3 employs a full-length foam midsole. This type of cushioning platform is developed to attenuate shock. It is also responsive to prepare the foot for toe-off. It is devised to wrap around the sides of the foot, particularly in the midfoot section to lend lateral stability to the upper.

Inside is a molded sockliner. It is fashioned to follow the natural contours of the underfoot for maximum coverage. It also complements the shock absorption of the midsole.

The upper of the Nike Free TR Flyknit 3 is made of the Flyknit, a proprietary fabric engineered to fit like a sock. In this model, a combination of stretchy and tight yarns is used. The stretchy component is placed on the vamp and the tongue to facilitate flexibility. The tighter material is utilized around the perimeter of the upper and the heel to add structure, durability, and support.

The lacing system integrates with the Flywire technology. These thin yet strong cables amplify the support needed for side-to-side movements. The eyelets on this model are set wider apart for a more tuned-in fit when the laces are cinched.

Another popular women’s trainer which employs a combination of the Flyknit material and the Flywire cables is the Nike Air Zoom Fearless Flyknit 2.
