Wouldn’t it be great to be a 8 and have shoes, not just the usual kind that are powered by air but, shoes that light up belch out smoke or fire with each stomp and also warm the feet so no cold feet and a loud programmable sound mommy can control with a remote. In the concept, these are like dragons or elf shoes. Inventors have devised machines that use slices of wheel that move in flip flop, zig zag motion, not the entire wheel, so the inertia is aimed where mommy wants to move the shoes of the elf. All mom and the kid may need is a good power pack like a foam battery they have to make the kid walk to where mommy wants, or for saving the kids if he walks too close to danger, and he would be able to kick like a martial artist if a dog tried to bite him. Power pack and motor science  has improved to where they can throw a rope over the side of a 40 story site and use a motor of James Bond type to lift you up to the roof about more than twice or more on just a charge of the Visa. And for older kids like Mommy and Daddy, the inventors say these wheel slices and the power pack machines could be used at high speed, avoiding rocks and other hazards at high speed by way of the machine, how fast were you going when you passed that Maserati? Finally a real use for a odometer you got built in when you bought your vamps!
