I decided to try making copies of Luke's feet using silicone casting. Here is the process casting one of his feet. It takes a very long time to make them, I now know how actors feel who have special prosthetics made.

These silicone feet are available to buy. They are custom made to order. They cost a lot to make as each pair is unique. $300 for one foot or $500 for a pair. Email me if you are interested.
