Visitors to Sky Zone must remove their shoes, but they won't need them anyway—their feet rarely touch the ground. An expanse of wall-to-wall trampolines lets kids and adults jump, flip, and literally bounce off the walls, thanks to angled trampolines that enclose the entire court. But that's only the beginning of what visitors can do on this springy foundation. At Sky Zone, classic activities get an antigravity twist: players leap feet into the air to avoid an out during games of ultimate dodgeball and slam-dunk basketballs with ease on the court's built-in hoops. SkyFit classes merge gravity-defying fun with fitness during instructor-led workouts that include calisthenics, core exercises, and strength-building aerobics to help guests shed calories without hurting their joints or taking a wrong turn on a treadmill. The springy terrain continues in the Foam Zone, where visitors plunge and hurtle through a pit of giant foam blocks.
