Does a store with computer scanners make a better orthotic?
Furthermore, if the "scanner" actually "casts" your foot, a custom made functional orthotic is not one that comes out of a box or that you receive a few minutes after being scanned. The "scanners" placed in various shoe stores, drug stores and supermarkets simply measure your foot in the same way that your foot is measured with a typical measuring device found in any shoe store in America.
Shoe store "scanners" simply measure the relative dimensions of your foot and steer the clerk to a pre made orthotic that they have on hand that most approximates your foot and shoe size. That is the simple truth of it.
