Ready for Performance! The adidas TenZone features a new pore structure of the sponge providing it with additional energy that will make the difference in tight matches. That extra energy transfers your wrist and forearm acceleration into ball speed and turns your topspins into even more dangerous weapons in your game. The compact structure of the top layer is the key to the increased spin capacities of the TenZone. Even on thin contacts the ball cleanly docks onto the surface without friction increasing the control over the ball during offensive topspin play. Technically versatile players with higher training volumes will get the full performance of the new adidas TenZone.
