This project is directly inspired by the machine shop at Autodesk's Pier 9 workshop. A lot of the machinery here is supported on the ground by machine leveling mounts. These helps the machinery stay constantly level even if their legs or the floor is uneven.
I wondered to myself why this innovation had never been used for a piece of footwear before, at least not to my knowledge!
A shoe that enabled your feet to stay constantly level could also be an advantage in a city such as San Francisco that has a number of hills.
Maybe there is a good reason why these parts have never been employed on the soles of shoes before (sprained ankles?)...
Let's find out!
During group project day here at Pier 9 I began testing the level-mount theory by making a Geta inspired wooden sandal that included one level mount on each foot underneath the toe:
This used a heavy duty metal mount that had a quite a loose action and swivelled easily. I thought it would be more helpful to have a mount with a stiffer action so that it was easier to balance on. Also the metal was hard to attach a rubber grip to.
I found that you can buy mounts made from Acetal which a stiffer action and should be easier to add some grippy material to.
