Today we're hanging out with my friend Evan making shoe lasts with rapid prototyping sand. He's holding one of the completed molds. If you'd like to learn more about sand casting (aka-rapid prototyping), come to one of his Thursday night pours. Since these are the kids first custom shoes, we are using this method. If you are going to make a long-term last, you can have a great one made locally, in Virginia, California, or other last making companies out of Maple. Today we are using sand.
