Nickelodeon blew it. They really blew a golden shot they had with making super cool shoes that let you jump really high. Their “Moonboots” were just cheap plastic with some weak bunjee cables in them.
I’m proposing better elastic with a secondary springboard on the bottom of the shoes.
These would be good for kids because they would learn about balance and be getting great exercise! They would also be great for adults for transportation.
