Nike G.T. Jump Academy Basketball Shoes The spring-loaded G.T. Jump Academy helps cushion your landing from skying for those boards. With a pair of soft foams stacked on top of each other and a curved heel, you can leap and land with confidence on any court. Two stacked midsole foams provide a cushioned landing after takeoff. Tall height and shape of the collar give you extra coverage and support when jumping high and often. Carved heel helps cushion your landing once you’ve gone skyward. Durable rubber outsole wraps around the sides of the forefoot for added stability and durability. Textured upper is structured and stable, yet soft and breathable.
