BUILT TO LAST. Tennis matches are fast, fierce and long. The NikeCourt Air Zoom GP Turbo combines an incredibly responsive, full-length Zoom Air unit with zones of durability so you can stay fresh longer. Revolutionary Responsiveness Full-length Zoom Air unit is stitched directly to the upper instead of being set into foam, so it responds to every step. Breathable Support Translucent textile breathes and shows off the Dynamic Fit system, which hugs and supports your foot during quick cuts and fast volleys. Durable Design Anatomically-designed toe box is reinforced on the medial side for added durability while sliding. Overlays are cut out in key places to enhance flexibility and breathability for an extra comfortable fit. Product Details Designed for wear on hard court surfaces
