A finite element models to (FEM) of the human foot, especially the experience of foot deformities such as pronation, Metatarsalgia, Flat Feet, Neuroma, Plantar Fasciitis, Arch Pain, and diabetes can be quickly developed and dealt into 3D solid .STL file using foot scan IQube 550. Solid abnormal human foot model consists of plantar facia and encapsulated soft tissue (indenter feet) with EVA rubber insole will be built into a 3D solid orthotic shoe insole in PowerSHAPE CAD 2015 then imported into the software ABAQUS 6:13 into 3D meshes FE analysis. Contact interactions that occur and be studied is between the indenter foot with shoe orthotic insole designed in various sizes. Abnormal foot contour obtained by the scanning process. Strategy curve-based surface modelling (CBS-modelling) was applied in this paper to obtain surface and solid models of shoe orthotic insole. 3D will be made some orthotic shoe insole to provide the size of the gap between the soles of the feet to the width of the insole designed. EVA rubber is used as an insole material. FEM analysis is used to obtain von misses stress from loading that varies on each insole with a predetermined gap width. The prediction results with FEM Abaqus 6:13. The result of the 3D solid with optimal insole shoe orthotic peak of 1,190x10 3 MPa von misses stress on the heel bone to the gap width of 1.75 mm.
