As requested, these are similar to my Wu Ying sandals but without the drawer. I printed these with wood filament and then sanded and finished them. Pi...ctures of that are here: http://imgur.com/a/uAFjf
They are certainly wearable- at least as much as any store bought sandals the same height. Short video of them being worn here: http://sendvid.com/jkiis66m
Remember to “ungroup" the strap-holes before you resize it. Also by scaling on the Z axis alone you can lower them to a height you are comfortable with. After you are happy with the changes use the "Mirror" function to make the left shoe.
3d model print parameters
Wood filament .3 layer height, 20% infill but I would suggest .2 since it took forever to sand. Sanded with 180, 240, 320, 400 and 600 grit sandpaper.... Then finished. Two coats. Three would probably be better.
