In the KD 13, we’re doubling the spring in the form of the double-stacked forefoot Zoom, allowing you more travel in the system and more energy back.”įrom a looks standpoint, the KD 13 offers a sturdy 5/8 cut with a low-slung Swoosh that dips into the midsole.

“The essence of a spring is to return the amount of energy you put into it. “The intent behind a Zoom Bag is similar to that of a mechanical spring underfoot,” says Ross Klein, Senior Creative Director for Nike Basketball. This encourages movement off the ball of the foot and pushes the wearer to quite literally play on their toes, while the doubled-up cushioning units work in tandem for a level of responsiveness that could not be achieved by a single piece of Zoom. Where the KD 12 used double-stacked Zoom in the heel, the KD 13 moves the doubled-up tech to the forefoot, placing a second kidney-shaped cushioning piece under the aforementioned Zoom Strobel.

Zoom Strobel tech - a full-foot Zoom Air unit placed directly under the insole - introduced on the KD 12 returns, but there’s one notable difference.
