Semi Reverse Innovative Design of Insole Shoes Orthotic for Patient with Club Foot

Club foot is one of the foot deformities caused by genetic factors. Patients with this characteristic have abnormal foot shape. Daily activities cannot be carried out by patients properly. The most important difficulty is finding shoes as the right footwear, precision and comfortable to use. The number of patients who are not small in Indonesia is an important topic discussed in this paper. Semi-Reverse innovative design (RID) is a Reverse Engineering application with 3D mesh data and able to get the precise and accurate surface contours of the club foot patient. Computer Aided Design (CAD) PowerShape 2019 was used in this paper to get a variation of the design of an orthotic ankle foot insole that fits the club foot patient's foot. The resulting output is in the form of three types of insole designs with geometric error tolerance of 0.08 mm.
