Why don Posture Control Insoles® have to be custom made?
Posture Control Insoles® are not passive supports that are custom fit to the shape of the feet. Posture Control Insoles® provide a stimulus to the feet, and the amount of stimulus is less critical so long as it is within an appropriate range. Trying to fine tune the dimensions further is not cost effective, and can be distorted by other factors that vary from one pair of shoes to another.
