• LIGHTNESS WITHOUT COMPROMISE: To help future champions stay supported as they hunt down every ball, ultra-light mesh has been added 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 DURABIILITY: The sole has been redesigned to meet the demands of the game more effectively. The tread is now bigger and thicker in the areas that wear the most, and reduced in places under less strain. The Jet Mach 3 Juniors sole and Michelin technology are more durable and less wear and tear is caused by specific tennis footwork.
• ORTHOLITE COMFORT FOAM INSOLES: The OrthoLite insole is molded to hug the shape of the foot. The properties of the foam composition make for exceptional comfort, breathability and durability.
• MICHELIN PREMIUM TECHNOLOGY: Michelin Premium rubber is the most durable composition ever developed. It offers increased resistance and optimal grip to meet the extreme demands of tennis footwork.
