跑步站立阶段足过度内旋是造成跑步损伤的主要因素。因此，跑步鞋需要防止在站立阶段过度内旋的特征。许多早期关于足内旋的研究集中在运动学参数上，如内旋角度（Nigg 1999）。在设计内旋控制鞋时，必须进行生物力学预测。基本上发生旋前的结果，这种力量作用在脚引起的地面反作用力（GRF）等，因此，在这项研究中，产生的力矩GRF周围的踝关节中心计算从实验结果，并讨论了如何的因素的时刻可以影响。
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.
