The moment lever arm is a predictor of the pronation in running

The over-pronation of foot in the running stance phase is a major factor of running injury. Therefore, running shoes need feature to prevent over–pronation in stance phase. Many earlier studies about foot pronation focused on kinematic parameters such as pronation angles (Nigg 1999). Going through biomechanical predictor is necessary in designing pronation control shoes. Basically pronation is occurred as the results of such forces acting at foot caused by the ground reaction force (GRF) etc. Therefore, in this study, the moment produced by GRF around the ankle joint center is calculated from experimental results and it is discussed how the factors of the moment can affect.
