Used for about a year in middle school club activities. Slight yellowing and some loss of shape. Slight tear in the mesh part on the left side of the shoe. The outsole is still in good condition. This speed model further refines quick movements that go beyond common sense. Equipped with MIZUNO ENERZY for enhanced cushioning. You'll be surprised at the difference from the moment you put them on. Jumping, landing, footwork. Each movement will exceed your expectations. You'll want to challenge plays you couldn't do before. The Z7 will pioneer the next standard in volleyball.
