A model for describing the complex movement of foot and ankle joint is crucial to correctly understand the regular motion of the foot. This study constructed a kinematics model based on the movement mode of the supratalar and subtalar joints and the morphological characteristics of talus. Assuming that the trajectories of the subtalar joint axis conducted are spherical logarithmic helixes, a ball-and-socket combining with a hinge joint was adopted to simulate the motion and the foot movement is restricted by the morphological components design of the model. According to the related data in the references, the range of the parameters and the characteristic of the foot movement simulated by the model was discussed. A series parameters of the model were set and the angles output of foot were obtained. The motion capture of foot was carried out to collect the dynamic data of the foot. The comparison between the complex kinematics simulation and the detected data showed that the motion of the foot and ankle joint could be conveniently described by the present model.
