Almost every shoe has rubber out-soles. It is such a waste when people get rid of shoes, and that precious rubber goes to waste. Rubber is very expensive, so we should try our best to reuse them. For this idea, I thought that we should take the rubber from the shoes, and turn it into tires of all kinds. We would then give them to teachers throughout the world for free because of the work they have to do. They are teaching America's future, and they deserve the best.
