The Yonex Aerus Z2 is a very lightweight shoe. Great for players who want to be as fast as possible on the court.It is important to note that a lightweight shoe will never provide as much support as other, slightly heavier models that are really focused on extra stability or cushioning. This makes this shoe less suitable for players with weaker ankles. RADIAL BLADE SOLE - Designed for confident change of direction. New outsole design for increased grip in vertical, horizontal and diagonal movements.DURABLE SKIN LIGHT - Combining the flexibility of rubber with the stiffness of hard plastic, the polyurethane-based Durable Skin Light lets you play lightly on your feet while maintaining a solid fit.TOE ASSIST SHAPE - The system provides additional support for the big toe, as well as the metatarsal and heel. Prevents the foot from shifting during sudden foot movements and changes of direction.3D POWER GRAPHITE SHEET - The 3D Power Carbon plate has been placed in the midsole, which reduces weight and increases stability during landing.SYNCRO-FIT INSOLE - Reduces the distance between the foot and the shoe, providing additional support around the heel, which guarantees maximum traction, comfort and efficiency.POWER CUSHION + - A raw egg can be dropped from a height of 12 meters above the POWER CUSHION+ mat, bouncing to a height of 6 meters without cracking.DOUBLE RASCHEL MESH - Double Raschel Mesh is an ultra-thin mesh that is extremely lightweight and durable.
