Moon Shoes are like mini trampolines for your feet! The shoes have anti-gravity effects, so as kids walk and jump, it feels like they’re walking on the moon. These lightweight shoes are made of high-density plastic with adjustable Velcro nylon closure straps. Moon Shoes feature a self-centering shoe platform with non-skid grip surface. The Moon Shoes come with two bases, two shoe platforms, 50 rubber bands, and an instruction sheet.
