Nike Air Zoom G.T. Jump Basketball Shoes OWN THE VERTICAL. Feel like defying gravity? Meet one of Nike Basketball’s most responsive cushioning systems ever devised for game shoes. The double-stacked Zoom Air works in unison with an external jump frame made from PEBAX® that's lightweight, springy and strong. The woven exoskeleton-like upper helps you feel fully connected, so you can move with confidence and power and defeat the force that holds you down. Elevated Cushioning System This cushioning system is through the roof! The full-length, Air Zoom Strobel unit (right up under your foot) is double-stacked with Zoom Air in the heel and forefoot. Add to that an external jump frame that is super-lightweight and springy, and you've got yourself 1 gravity-busting sensation. Exceptionally Light and Strong The leno-weave upper uses a grid of twisted strands of composite fibers, making it extra strong but incredibly light. Together with the sculpted, slightly lowered midsole and jump plate, it's designed to help you feel stable and fully connected to your power. Lightweight Herringbone Traction The thin-web rubber outsole uses a zigzag herringbone pattern that is tried-and-true on the basketball court. A cutout under the arch and perforations throughout help reduce weight and keep it flexible. Flywire cables up the sides loop around the laces to anchor you down when you lace up. Cushlon in the midsole is a hollow frame of supportive, resilient foam. Air Tongue System provides cushioning over the top of the foot.
