A lightweight Nike Air unit at the bottom of the upper gives KD the cushioning and comfort he needs to thrive during a long season.KD loved the 15’s underfoot experience, so we took inspiration from the previous iteration and added a bottom-loaded forefoot Zoom Air unit for extra pop and snappiness when the game hits high speeds. Responsive full-length foam adds a soft, comfortable sensation.Grooves and ridges in the sole help provide multidirectional traction and court feel. A stiff piece under the arch helps keep the shoe stable and help you smoothly transition from heel to toe.Multilayer mesh in the upper is lightweight and dimensional with a broken-in feel. Added thickness in strategic areas helps to keep your foot in place by reducing small movements.Good preowned condition- some dirt marks and small “scuffs” {SEE ALL PHOTOS). Inner heal does have some light discoloring. SEE PHOTOS 8 thru 12. I don’t believe they were worn outside or on the court.
