How the speedy greedy works
We invented speedy greedy to help kids get to school faster.
There are boosters on the side of each shoe .To start the boosters you press the button on the side of the booster.
There are wheels that come out of the bottom of the shoes .To make the wheels come out press the button on the boosters.
There’s a break on the outside heel on each shoe. There’s a wire coming out connected to the break it’s got a grabber on it.
It makes walking safer and fun.mostley for teen ages or over.easy to start.
