A human foot model is developed and the biomechanical stress distribution is investigated. As foot is the lower extremity of the body, the contact surface area holds the weight of the complete body during activities such as walking, running, climbing etc. The study of the forces acting on the foot is important, as it helps us understand the different types of injuries. A 3D model from CT scans was generated relating the anatomical domains of bones and soft tissues using Comsol Multiphysics software tool. The computational model of the foot structure was utilized to evaluate the distributed vertical ground reaction forces. The contact pressure distributions will be generated between the plantar foot area and the ground support for different types of foot depending on the arch height and ankle alignment. Pressure distributions on the foot are dependent on the medial longitudinal arch height, corresponding arch index, the angle of transverse arch rotation, and the elastic properties of the skin, bone, and cartilage.  These parameters were used to classify and analyze different types of foot to study the mechanical load distribution.
