Mizuno Lady Wave Nirvana 9 Running Shoes Full-length Composite Double Fan Wave - Support style Wave plate which engages earlier to prevent over-pronation. Provides excellent cushioning by dispersing the force of impact across a larger surface area. The stability aspect of Wave technology is gained by the construction differing between the outside (lateral) and the inside (medial) of the shoe, therefore resisting the compression of the midsole in high pressure areas. Sensor-Point Technology - Mizuno's revolutionary suspension system which uses studs that connect the Wave plate directly to the ground, thereby enhancing stability and traction. SmoothRide Engineering - Smoothride components have been added to maximise the energy transition from heel to forefoot, giving you a smoother step and improved performance through optimal energy transferral through the step. NEW - SR Touch - A finer density cushioning compound in the heel which absorbs impact stress better than previous technologies. AP+ Midsole - Lightweight and responsive. A more resilient base for maximum responsiveness with every foot strike.
