KD prefers comfort, with a shoe that feels somewhere between "a sock and a lightweight runner," which is why Nike made the KD 11 is his most comfortable shoe to-date. On the KD 11, the third consecutive KD signature to feature Nike's most adaptable textile technology, the Flyknit gets a little more plush, a little more "broken-in" and a thus a lot softer. The shoe itself has a rubber cup sole that houses the Nike React and Nike Zoom. The former cushions between court and body, while the latter sits just under the foot to provide response. A key component in the resulting system was identifying the correct thickness for the foam element, which Chang notes is taller than in typical basketball shoes.
