3D printing my own sandals/zori

I got some TPU to print a phone case, which went pretty well, so I started looking around for other things to print. I've seen people print entire shoes out of TPU, but none of the designs I've seen appealed to me, so I decided to just go for a sandal. TPU unfortunately, doesn't have much traction, so I'm gluing strips of foam rubber to rhe bottom.

Next step: creating insoles and straps! Since this is a prototype, these straps are just for testing how grippy I can make this and in which conditions.
