3D Model of a Shoe Last


I am looking forward to model a special shoe for a disabled person who suffers from Charcot Marie Tooth disorder (an extremely rare genetic disorder)
for which i need a 3d model of a Shoe Last over which i would be able to model the structure i have designed to support his feet and Avoid Foot Drop AND
want to model Insoles that suits the users special requirements (following the contours of his feet).

It would be of great help for my project & the disabled person.
