The region of interest is bounded by part of the arch of the foot and the ball of the foot (joint of metatarsal heads and phalanges). This model does not include the toes. The model is shown as assembled for the surface contact calculations. The plane, marked as the floor, is a rigid surface that is moved towards the forefoot model during the finite element model calculations. The finite element model of the forefoot includes material properties for the bones, skin (epidermis and dermis), fat, and muscles. The skin was represented with the first layer of elements around the forefoot and is marked by an orange element. The second and third layers of elements were fat, marked by a yellow element. The outer boundaries of the five metatarsal bones are shown in green. The rest of the elements are considered part of the muscles (blue).
