Designed for quickness and control during competition on hard courts, the NikeCourt Air Zoom Ultra React Hard Court Women's Tennis Shoe features ultralight materials and responsive cushioning. ULTRALIGHT DURABILITY High-wear areas of the shoe are layered with moulded details, a lightweight material that adds durability without the extra weight. DYNAMIC LOCKDOWN Flywire technology is made of ultralight, super-strong cables that integrate with the laces for support when you cut and sprint. MAXIMUM RESPONSIVENESS Nike Zoom Air cushioning in the heel and forefoot is lightweight, low-profile and incredibly responsive, designed to bounce back after every landing and power your next move. A full-length Pebax® plate distributes the compression force of your foot over the cushioning units to amplify their response.
