Currently foot impressions are scanned via a photogrammetry scanner attached to an iPad.
Curious to see how expanding foams would interact with our 3d printed structures, we tried out several different density foams in small samples.
In order to save ourselves time and money, we often remove the soles from existing shoes, and use the upper just to test our new outsole/midsole designs. This requires heating the shoes in a toaster oven to soften the heat activated glues commonly found in mass produced footwear. We then add acetone which dissolves the glue, and allows us to pull them off without much effort.
