Last fall, in course of research for a related tech development for footwear, I had the good fortune to meet the team at 3D-Fit at the AOPA conference in Indianapolis. I used the app provided to scan my feet and sent off to the team. 

In only a few short weeks, the team at 3D Fit were able to build exact matched 3D printed models of my feet and built me the most comfortable footwear I have worn in my adult life.
