My local Red Wing store had a gadget that mapped my feet in 3D. I've since seen links the company gave other people to profile pages showing their results. While the machine was doing its beepy-flashy dance, I told the sales guy I bet he could beat it. He did. The machine recommended a width they had in stock. Sales guy himself told me to order in a different one. There are old patents for electro-mechanical devices. The dream goes back a long time. Meanwhile, even bespoke makers in London do test fittings. They'll often start with mock pairs made of scrap leather, then investigate the fit destructively. It isn't just how the feet are shaped and how they move, but how the shoe will move with them, how the shoe materials will form over the last, how the shoe materials will stretch and sag over time, how the design of the shoe itself will affect the biomechanics. It's an incredible trade.
