The main problem I wanted to overcome was the availability of tools to create these shoes. I wanted it to be possible for anyone to create their own shoes even if they had no sewing experience.
In the end I was able to make shoes using only fused plastic and cardboard. The construction of the shoe is done with an iron. As the layers of plastic are melted together by the iron, they create a durable material which completes the sole and outer material of the shoe. All of this is wrapped around a cardboard insole.
