BenefitsTennis
Lightness without compromise
To help future champions stay supported as they hunt down every ball, we've added ultra-light mesh to the upper and a natural roll for extra momentum.
Comfort and support
The KPRSX system has been updated to provide maximum cushioning at all stages of the game. The entire heel is now protected with softer EVA foam for shock absorption in any position. And the heel rocker helps the foot transition from slowing down to powering up. This support is like nothing else.
Sole durability
The sole has been redesigned to meet the demands of the game more effectively. The tread is now bigger in the areas that wear the most, and reduced in places under less strain. The Jet Mach 3 Jr's sole and Michelin technology are more durable and less wear and tear is caused by specific tennis footwork.
