Shoe Spring

My space tool is a coil or spring to make astronauts jump higher. The tool helps astronauts when they are in space. Sometimes gravity is not helpful. So, then you need the shoe spring to attach to the heel of the shoe. Some astronauts need the extra jump to get to places they want to go. This tool is unique because it does not use any type of gas, electricity, or any resources other than 3D printing.
