Abstract

The shoes selection as the right footwear is very related to the feet comfort, especially in the selection of shoe materials. The shoe consists of three parts: insole, outsole, and upper shoe. The right outsole material will affect the comfort of feet during activity. This paper demonstrates a mechanical testing method on optimization of outsole material based on computer aided engineering (CAE). The outsole design on milutes diabetic patients in previous studies used as the basic design for mechanical testing at CAE. Three types of mechanical testing on Abaqus software 2016: bending, torsion, and plantar plessure used in this paper to determine the optimal outsole material as outsole material shoe orthotik. The test results showed that the material EVA rubber type declared with optimum characteristics of the von mises stress 0.0013 MPa, maximum principal stress 0.0036 MPa and features shock absorption of 5.01562 mJ. This data can served as a basic reference for the process of manufacturing the outsole of shoe on CNC machines.
