A super interesting project is getting crowdfunded on Goteo, looking to create some sort of open platform to create ultra personalized shoes, in open source:
The Open Shoes project consists on creating a healthy, modular and open source footwear, that you may make for yourself, using new technologies, or can acquire it at a reasonable price. The rise of 3D printing allows us to take a first step in this direction.
Being open source, the user or a professional can modify standard designs and tailor it to some specific needs. Therefore, we aim to create a community around the project of interested users, both professional and private, that will be a key part to being able to offer alternative versions or upgrades.
