The Yonex Aerus Z2 is a very lightweight shoe. Perfect for players who want to be as fast as possible on the court. This is a wider version of the Aerus Z2.It's important to remember that a lightweight shoe will never provide as much support as other, slightly heavier models that are more focused on added stability or cushioning. This makes this shoe less suitable for players with weaker ankles. POWER CUSHION  - The Power Cushion system effectively absorbs impact energy from impact and transfers it to the next move, the take-off. Compared to traditional urethane, Power Cushion delivers three times more energy.POWER CUSHION ＋ - By adding a special insert made of flexible resin, the shock absorption of the existing Power Cushion system has been significantly increased by 25% and rebound by 12%.
