Nike Free RN Flyknit: Flexible is the name of the game

From the outsole to the midsole, the priority of the Free RN Flyknit from Nike is flexibility. For unrestrained foot bend, the Auxetic Tri-Star outsole features diamond-shaped cut-outs that make it pliable and natural-feeling.

Comfortable cushioning

Loads of runners have mentioned that the shoe has "generous" cushioning. The IU002 midsole (the shoe's most significant update) is great at dampening the impact and is so "soft," their strides were pain-free and enjoyable.

Supportive in all the right places

The Flyknit upper, apart from giving ventilation, also provides a "sock-like wrap." Road runners highly appreciate it, especially during sharp turns and uneven terrains. 

Working with the Flyknit upper are the Flywire cables. Not only are they light, they're also great at creating a lockdown fit.
