Development of inexpensive prosthetic feet for high-heeled shoes using simple shoe insole model

Margrit R. Meier, PhD, et al.

The large majority of prosthetic feet are made for low-heeled shoes. Only a few models allow a heel height of up to 5 cm. However, a survey by the American Podiatric Medical Association indicates that most women wear heels over 5 cm; thus, current prosthetic feet limit most female prosthesis users in their choice. Some prosthetic foot components let the user adjust to different heel heights. However, these feet change only the angle of the ankle without adjusting the shape of the prosthetic foot to match the insole shapes of the shoes. The aims of the study were therefore (1) to develop a model that allows prediction of insole shape for various heel height shoes and different shoe sizes and (2) to develop and field-test low-cost prototypes of prosthetic feet whose insole shapes were based on the new model. An equation was developed for the calculation of insole shapes that is independent of shoe size, thus applicable to all sizes. Field testing of prosthetic feet fabricated based on the equation was successful and demonstrated the practicality of the equation.
