This research details a procedure for the systematic design of foot orthotics based on simulation models and validation of the same with subsequent experiment. The present model may ultimately to replace the use of empirical tables for the designing of foot orthotics in accordance to the weight and activities of end-users. This present model is so general that it can simulate different kind of orthotics, loading conditions and material properties to give the desired output. Finally, the proposed model and the corresponding results may lead to the form of design basis for new generation foot orthotics. The methodical approach to the development of engineering analysis models using the FEA technique. Orthotic devices have been commonly made from plastics like polypropylene. However, insufficient mechanical properties, labour intensive preparation process, long client’s visiting times urge us to seek an alternative. Presently, two different advanced composite materials (Glassfiber, Basalt-fiber) have been chosen for the analysis purpose to achieve the low weight and High Strength.
