Mizuno Lady Wave Inspire 9 Running Shoes SR Touch - A finer density cushioning compound in the heel which absorbs impact stress better than previous technologies. Mizuno Wave - 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. Double Fan Shaped Wave - This extended Wave plate offers pronation control support by activating the wave plate earlier in the running cycle. AP+ - Midsole cushioning compound which maintains lightweight effective cushioning through the cycle. Mizuno Intercool - An innovative full-length ventilation system which gives the runner outstanding breathability and comfort, keeping your feet dry and cool.
