This paper presents the biomechanical analysis of lower limb bone model delimited at foot. Virtual model of the foot has been obtained, from scans. These scans allow you to create solid models in a CAD package also presents the finite element study (biomechanical analysis) for the phases of propulsion and stabilization motion presented by the foot, where values were the stress distribution, displacement and strain of the foot for a weight and height range of 60-90 kg and  of 1.50 - 1.90 m respectivaly. The values of stress, displacements and strain obtained are important because they identify the bones that are subject to greater damage (critical). With these results we propose part of the problem of obesity, and people engaged in sport, to demonstrate the behavior and possible damage in the various bones that make up the foot. In addition to generating a new design of a prototype prosthetic foot with new materials.
