Abstract. The work presented in this paper is part of a research project which focuses on the development of cost-effective and accurate computer-aided design and engineering (CAD/CAE) tools for the determination and optimization of design parameters used for the production of comfort footwear (project acronym: OPT-SHOES). The evaluation of these parameters necessitates the development of (a) highly-accurate foot and shoe models, (b) appropriate FEM of the foot and shoe components, and (c) highly-accurate simulation tools based on human behavioral models for performing FEA. In the present paper, we focus mainly on the production of a bio-model of the human foot from dense CT scans. The produced bio-foot includes material properties for hard and soft tissues. We present a thorough overview of existing approaches and methodologies and the results of four reconstruction approaches. For the reconstruction process two commercial software and two methods based on Poisson surface reconstruction are employed. All produced foot bio-models are compared and discussed with respect to their application for FE analysis. For the simulation purposes between foot, footwear and the ground, we have developed a set of material properties for the footwear and ground structures.
