High End Performance Shoe for High-Level PlayersHEAD Duraforce Technology: HEAD's Duraforce cushioning technology consists of a unique interlocking coil structure encapsulated within a resilient polyurethane form. When the foot makes contact with the ground, the encapsulated coil fibres are compressed, absorbing shock. As the foot reaches the end of its stride, the heel waves of recoil rebound, producing an ipward force like that of a resilient spring. The benefits are excellent shock absorption, more comfort, decreased foot fatigue, and outstanding stability and motion control.HEAD Cooling System: HEAD Cooling System provides state-of-the-art moisture management, creating a dynamic "climate control" system within the shoe.
