Patients affected by serious foot pathologies often require special orthotics to stand and walk correctly.

Abstract

Patients affected by serious foot pathologies often require special orthotics to stand and walk correctly. Skilled operators obtain such insoles on the basis of manual procedures and following the prescriptions of orthopaedic technicians. The process is handicraft and time consuming. The paper presents a virtual prototyping approach which is based on dedicated foot scanners, CAD-based design tool and milling machines to obtain the bespoke footwear orthotics. The major contribution is a geometric procedure to design complex insole shapes starting from the foot scan and highly customized shoe lasts which are required in case of important deformities. The approach has been tested on several patients thanks to the collaboration with a partner insole producer and some orthopaedic centres. Patients have generally reported positive feedbacks on the comfort and functionality of the insoles.
