For players seeking a trusty and stable shoe, the Head Revolt Pro 5.0 Clay delivers the support you need when grinding from the baseline, while adding a comfortable and cushioned ride. The upper material remains supportive and durable, while providing increased flexibility for a comfortable fit and feel. Under the foot lies a bed of Dynafoam, which has been engineered to disperse shock, and keep you feeling fresh during long matches. What really stands out with this version 5.0 is the all new Core Control 3D sidewall, which gives the ultimate confidence on aggressive lateral cuts, and is beneficial for players who slide into their shots. Head's signature Hybrasion+ rubber has been formulated to increase durability and is formed into a full herringbone tread pattern for enhanced grip on clay courts.
