The KPRSX system provides optimum cushioning in every phase of the game. The entire heel area is protected by EVA foam to absorb shocks whatever your stance. In addition, the rocker heel makes it easier for the foot to roll off the ground, making for a smooth transition from stopping to acceleration. The result: unmatched cushioning.

We've added ultra-lightweight mesh to the upper and extra responsiveness and buoyancy to the sole to help you run faster after every ball while enjoying just the right amount of support.

The sole is designed to respond precisely to the demands of the game: the tread surface is increased in areas with the highest abrasion and lightened in areas with the lowest. The JET MACH 3 Jr outsole, combined with Michelin technology, offers enhanced durability to reduce the wear and tear caused by tennis-specific movements.
