This is the kind of 3D printing I'd love for shoes, at least early on in this kind of application... I'm taller than most women, so choosing the right heel height can be a challenge. It would also be so nice to have the option to swap that out for different events. Maybe just having the heel be 3D printed, rather than the whole shoe -- at least in the more immediate future. When 3D printing for shoes really takes off, there's some major potential!
