"The shoe of choice for arguably the most powerful athlete on tour, Rafael Nadal, the Air Max Courtballistec 1.3 is the perfect match for his blistering court speed. Nadal's amazing court coverage demands the highest level of support, stability and traction. In addition, the Courtballistec 1.3 is also designed to be extremely durable and cushioned. This particular colorway sports the "Bull" logo on the medial side of the upper. Nike has brought brand new technologies to the table with LunarLite in the midsole and DragOn X in the upper. LunarLite offers supreme light weight cushioning while DragOn X is up to 30% more durable than it's predecessor, DragOn. A new look, with new technology places this shoe one step ahead of the competition. Features a six-month outsole durability guarantee."
