Computer-Aided Design and Manufacturing of Customized Insoles

The authors developed a method for manufacturing customized insoles. It leverages advances in pressure analysis of the foot, including research on insole materials' mechanical properties and the design of insole components. Using a plan tar pressure measurement system and computer numerical control (CNC) or rapid-prototyping technology, it determines the distributed average pressure for each region of the foot, creates a model of the sole, and manufactures an insole. The method makes insole design much more precise, which enables rapid manufacturing and ensures more ergonomic and comfortable insoles.
