Abstract: This study presents and evaluates a new method for footwear insole customised design with a focus on computer-aided and ergonomic design. Prescribing orthopaedic insole is a way to prevent or treat musculoskeletal problems. The conventional design and manufacturing methods do not pay enough attention to the insole's design requirements mentioned in the prescription. Moreover, doctors do not have proper control over the treatment process. Thirty patients were studied, in a pre-design and post-design period at an orthopaedic centre. Results showed that using anthropometric data and the non-uniform rational basis spline (NURBS) system in footwear insole design improves foot treatment. Also, design accuracy leads to treatment improvement and in NURBS and anthropometric data with increasing design accuracy. It seems the customisation by focusing on anthropometric data and the NURBS system leads to better control and prescription through improved treatment modalities. It also helps doctors and designers to improve the design of the insoles.
