Kevin Durant has been recognized as one of the most versatile players in the game. His KD 9 signature shoe helps keep him fluid in his every move, “Once I seen the KD 9 I was like, ‘Wow. We could really do this,’” Durant said. “They presented this shoe to me last summer, along with the new Zoom bags. So it just worked out well.” and this colorway of KD9 is the most popular so far
Today we are talking about it .
It with a sock-like Flyknit upper and reimagined Nike Zoom Air cushioning to enable a natural motion every step of the way.
For the material : it utinilized the Flyknit which was backed by nylon
The flexibility of the material gives it its acute support while allowing the material to react the way when playing .this type of Flyknit that was utilized on the Nike Kobe 9 Elite or even the Nike Hyperdunk 2016 Elite. it is actually great and durability .it provide enough structure and support for the foot for this setup
For the supporting ,it is just so so , as my experience , it is not very good at for those who playing the guard . it is not enough for them .
For cushioning , it nice.Full length articulated Zoom Air used , it is really great . This cushion setup is everything anyone can want and ask for a lot of fans .full length Zoom returned to the Nike Lebron X and the KD6 Elite. For me , I like I every much . the court feeling is great . TPU bumps located towards the forefoot where the Zoom unit is segmented to provide flexibility
Swoosh did a superb job with the Nike Zoom KD9 is nice 
there is a ZOOM logo on the side 
The KD. logo on the heel
For the traction , it utilized the rubber traction which was super sticky at times caused my foot when I am playing .As good as the rubber traction compound was, it can be used outdoors, but it is not very great as my experience .
Overall .the KD 9 is great for cushioning and material , the size is true . flexibility of the material and so on .
